This paper explains the similarities and highlights the differences between the two joining processes to help determine which joining method is most desirable. • We strive to measure quantities ordered as closely as possible; however, due to manufacturing tolerances at the mill, please allow for a ±10% variance when ordering. As a wholesale supplier to jewelers and other industry professionals, Rio Grande wants to avoid presenting wholesale pricing to retail consumers. The most commonly used brazing filler metal types, used to join copper tube and fittings fall into two distinct categories: Whether the joining process being utilized is soldering or brazing, there are certain basic steps that should be followed to consistently obtain strong joints. Accessories. While a brazed joint is demonstrably stronger than a solder joint, the Rated Internal Working Pressure, that is the 24/7 allowable working pressure of the system, is lower for annealed tube (see Copper Tube Handbook, Tables 3a through 3e). Both lead-tin and silver-tin material can be soldered. Within our extensive range, you will find an Alpha flux cored solder wire that meets your specific needs.

The depth of overlap or socket depth in a lap type or capillary joint fitting is specified in manufacturing standards ASME/ANSI B16.18 and B16.22 for solder pressure fittings. See current pricing on all products based on published daily metal markets. Is It True That Electrolysis Can Cause My Copper Tube To Fail? Although 100% penetration and fill of the capillary space fitting is desired, a solder joint fill of 70% fill (or no greater than 30% voids) is considered satisfactory to obtain joints that can withstand the maximum recommended pressures for soldered copper tube and fitting systems. Consequently, this must be taken into account when deciding whether to solder or braze. As such, the filler metals for soldering and brazing copper and copper alloy tube and fittings must have melting temperatures below this temperature. Can Copper Tube Be Used in Steam and Steam Condensate Piping Systems? This does not appear to be a valid customer number for Rio Grande. Safe Flo 1 lb. Be sure to thoroughly clean & wire brush the adjoining pieces. It is important because 700°F/371°C is the temperature at which copper begins to anneal, or be changed from hard temper (rigid) to annealed temper (soft). Please call or chat. Since brazing temperatures must exceed the melting point of the brazing alloys, between 1,150°F/621°C and 1,550°F/843°C, the process of making a brazed joint causes the base metals to anneal or soften, resulting in a reduction in the overall strength of the assembly. MST. The overall amount of annealing that occurs, and thus strength that is lost, is determined by the temperature and the time the material spends at that temperature. Process recipes will differ depending on the alloy composition. This standard and its procedures deal with end preparation, cleaning and the proper application of heat and filler metal. Iron tips are cheaper and durable. Manage and update your account information, including contact and payment information, at your convenience. Tube and fitting are then solidly joined using a filler metal that is melted into the capillary space and adheres to these surfaces. Soldering creates fumes and smoke. Creation of the fillet when fabricating the brazed joint greatly minimizes this possibility. Keep in mind that hardness is changeable (by annealing or heat-hardening) and is relative among metal types (each temper will feel and handle differently from one metal to another). The spring on the stand holds the hot soldering iron. Therefore, other elements are added to alloy with the tin to provide strength and make the filler metal easier to use. The melting point of copper (Cu) alloy UNS C12200 is 1,981°F/1082°C. The basic difference between soldering and brazing is the temperature necessary to melt the filler metal. In addition, the U.S. Patriot Act requires all suppliers of precious metals to maintain full contact information for all of its customers. How to Prevent Corrosion of Copper Tube in Underground or Buried Applications. Besides the strength of the filler metal in the joint, the overall strength of the joint or assembly (tube, fitting and joint) following the joining operation must also be considered when choosing whether to use soldered or brazed joints. This solder kit comes with the basics you need to solder copper water pipes. Note that the wire will get hot, so you should consider holding it with some tweezers or similar. Our teams are available and continuing to accept orders between. High end soldering tips come with iron coated copper tip which provides the best of both options. However, they cannot hold or transfer heat as effectively as copper tip. The soldering wire included for your soldering tip is made from brass and helps with getting rid of excess solder.

After all, VOBst wire … Check out our free online jewelry videos and Wire Wrap Jewelry Patterns! Safe-Flo Silver Wire Solder This Oatey 1 lb. Riveting. This fillet, or cap as it is often referred to in the trade, permits the stresses developed within the joint (by thermal expansion, pressure or other cyclic reactions such as vibration or thermal fatigue) to be distributed along the face of the fillet. Create and update a 'wish' list of products you have selected but are not yet ready to purchase. Because of the increased strength of brazing alloys, even this rather small amount of fill penetration will result in a properly fabricated brazed joint stronger than the tube and or fitting themselves. However, this increased strength generally comes from filler metals made of materials that melt at higher temperatures. The basic difference between soldering and brazing is the temperature necessary to melt the filler metal. Tinned copper wire is very easy to solder making it useful for connecting components and internal contacts. The cable is also responsible for extending the lifespan of your suggestions by holding the iron being worked on. To accomplish this, filler metals stronger than those composed primarily of tin must be used. All rights reserved. This dead-soft, 20-gauge copper round wire is the bread-&-butter of jewelry making; it is ideal for creating components and for a wide variety of techniques. The melting point of copper (Cu) alloy UNS C12200 is 1,981°F/1082°C. ; 26-24 gauge are good sizes for stringing pearls and beads with small holes. Heating is often achieved electrically, by passing an electric current (supplied through an electrical cord or battery cables) through a resistive heating element. The price for higher quantity price breaks will appear in your shopping cart. The filler metal is a metal alloy that has a melting temperature below that of either the tube or fitting. With this change in temper comes an inherent loss in strength - hard temper copper is stronger than annealed temper copper. For starters, you need wire wrap (most commonly 30 AWG silver-plated copper wire with Kynar™ insulation in a variety of colors), a wire wrapping/stripping tool, and preferably some machine tooled wire wrap sockets. A major difference between brazed and soldered joints is in the amount of joint overlap or fill necessary to develop full strength of the joint. SAFETY DATA SHEETS: View the SDS(s) for the information you need to use this item. These tried and true methods are in a number of ways similar, yet there are also several distinct differences that set them apart. © 2021 RioGrande.com. Corrosion of Mixed Metal Fire Sprinkler Systems, Why Do I Have Blue/Green Staining Of My Bathroom Fixtures. In order to ensure any equipment ground continuity, you must bond (clamp on each copper pipe and a wire connected to each clamp) the copper pipe pieces together over the PEX and shark-bite fittings. Spool, 20-Ga., Dead Soft, SDS. It has not occurred to me that soldering brass and copper looks so rewarding. Beadsmith EZ-Rivet Tool.

Safe-Flo Silver Wire Solder is made from a lead-free alloy specifically formulated for use on lines that carry drinking water. Key to success with this product is proper preparation of the copper pipe. The tin around each of the copper strands makes soldering the wire a breeze and, moreover, prevents the copper from oxidizing, especially in salty coastal environments. For many years the two most common methods of joining copper tube and fittings have been soldering and brazing. The most common method of joining copper tube is with the use of a socket-type, copper or copper alloy fitting into which the tube sections are inserted and fastened by means of a filler metal, using either a soldering or brazing process. Access and print your order history and invoices any time you need them. Am I Getting Quality Copper Tube & Fittings? This solder requires the use of flux (not included) and features a wide melting range, from 415 degrees Fahrenheit to 455 degrees Fahrenheit. Please allow 3-5 business days for a response. Soldering Tools. Prior to 1986, the most common solder filler metal used to join copper alloy tube and fittings was 50/50 solder, which is 50% tin (Sn) and 50% lead (Pb). Place the tip of the iron on the wire and let it heat for a few seconds. According to the American Welding Society (AWS), it is suggested that the brazing filler metal penetrate the capillary space at least three times the thickness of the thinnest component being joined, which is usually the tube. While there are other elements found in BAg alloys besides silver, the majority of BAg alloys may contain silver content of anywhere between 24% and 93%. The brazing temperatures for most of the brazing alloys used to joint copper piping systems (BCuP and BAg alloys see below) are roughly between 1,150°F/621°C and 1,550°F/843°C. This is an important dimension because ideally the filler metal should be melted into the capillary space so that it flows completely to the back of the fitting cup and completely bridges (fills) the space between the tube and the fitting. If you want to join two wires with solder, the first thing you should do is to tin the two wires. Material used for soldering iron tips is also an important factor to consider. Commissioning and Disinfecting Copper Plumbing Systems, Copper Piping Systems and Acoustical Sealants. The higher the temperature, the less time it takes to change from hard temper to soft temper. 9. The tinned-copper braided strands are what make the wire so extremely flexible. Tinned Wire is a copper wire that has had a thin layer of tin applied to the outer surface of the material. Whether the joining process being utilized is soldering or brazing, the tube should be fully inserted into the fitting to the back of the fitting cup. Use it to cut long component legs, or to strip the end of a wire.. Solid and hollow rivets in brass, copper, and aluminum. Ceramic and charcoal soldering boards, annealing pans, jewelry soldering stands and third hand tools. If you need a quicker response, please call or chat with one of our Rio Grande agents. While brazed joints are stronger, and in general are more resistant to fatigue (vibration, thermal movement, etc. When finishing your pieces, also keep in mind that the harder the metal is, the brighter a finish it will take.This wire is sold on 1-lb. The solder in this picture is coiled inside a plastic tube; it is pulled through the top as needed. With the prohibition for the use of 50/50 (Sn/Pb) solder, many new and stronger lead-free alloys have been developed and are in common use today for all soldering applications. 2020-2021 Tools and Equipment Catalog p. 815. American Welding Society: Soldering Handbook - 3rd Edition, American Welding Society: Brazing Handbook - 4th Edition, AWS A5.8/AWS A5.8M: Specification for Filler Metals for Brazing and Braze Welding, ASTM B32-04: Standard Specification for Solder Metal. Push the … The best option is to use hollow soldering wire with a rosin core; rosin is a flux chemical that helps the solder flow and reduces the effects of oxidation. A Berkshire Hathaway Company.

This dead-soft, 20-gauge copper round wire is the bread-&-butter of jewelry making; it is ideal for creating components and for a wide variety of techniques. This temperature is much more important than just an arbitrary definitional threshold. For soldering 44-pin chip carriers to a board using soldering preforms, power levels were on the order of 10 watts and solder times approximately 1 second. However, the use of pure tin (Sn) would make a very weak joint, and as with any pure metal would be very difficult to work with. As such, the filler metals for soldering and brazing copper and copper alloy tube and fittings must have melting temperatures below this temperature. The Benefits of Signing Up For a Rio Grande Account, Copper Round Wire, 1-Lb. Cleaning Sponge Soldering Procedure Specification CDA-2001 for Soldering Copper and Copper Alloy Tube and Fittings Using a Manual Air-fuel Torch and ASTM B 828 Procedures. ; 22-20 gauge are good all-purpose, versatile wire sizes, thin enough to be able to string on most beads. That temperature is defined to be 842ºF/450ºC by the American Welding Society (AWS) but is often rounded to 840ºF. the challenge to date has been making the physical connection between the magnet wire and #22 solid copper wire that goes to the ADC. spools.The color of copper is popular for a variety of mixed-metal and alternative metal designs; its affordability adds an additional facet to its popularity for both maker and clients. SCOPE This procedure is applicable for the soldering of copper tube and copper alloy fittings in the range of 0.375” nominal to 8.0” nominal. It is suited for purposes such as DIY soldering projects, electronics repairs, home crafts-making, and many more. In a brazed joint fabricated without the well-developed concave fillet, all stress would be concentrated at the sharp point of contact between the tube, braze alloy (filler metal), and the fitting, possibly leading to development of a stress fracture in the tube at that point. The Plusivo Soldering Kit 21-in-1 set: The Plusivo Soldering Kit is a full set of soldering tools for hobbyists, electronics and electrical learners, enthusiasts, beginners, and professionals. Sign up for our email list for the latest jewelry-making updates from Rio Grande, including news about sales, product releases, events and more. Then add some solder until the wire is soaked with solder. The damp sponge is used to clean the tip of the iron.Solder braid is used to remove solder; solder is "soaked up" into the braid when it is heated by the soldering iron. This is known in the industry as the AWS 3-T Rule. The wire cutter is a very handy little soldering tool. Above that temperature, the process is brazing. This type of joint is known as a capillary or lap joint because the socket of the fitting overlaps the tube end and a space is formed between the tube and the fitting. If the filler metal melts below 840ºF the process being performed is soldering. BAg Alloy (pronounced bag) - where the B stands for Brazing and Ag is the chemical symbol for Silver. The primary element used in solder filler metals is tin (Sn), because tin has affinity for copper and wants to adhere to the copper alloy tube and fitting. Soldering a joint in pipes that contain even tiny amounts of water is nearly impossible. Figure 1. Therefore, a BCuP brazing alloy is primarily a copper-phosphorous brazing alloy that may contain from 0%-30% Silver (Ag). This space is called the capillary space. In a brazed joint, full insertion of the tube to the back of the fitting cup is still highly recommended; however, complete fill of this joint space throughout this entire length is not necessary to achieve full joint strength. Soldering Two Wires. Most of the heat from the torch goes into turning the water to steam, so the copper won’t get hot enough to melt the solder. These consist of alloys that are still primarily tin with the addition of various combinations of other elements, such as nickel, bismuth, antimony, silver and even copper. Because of nationally mandated requirements set forth in the Safe Drinking Water Act, lead bearing solders were prohibited for use in potable drinking water systems. Tinning the wire strengthens the coppers natural properties making it more resistant to high temperatures, humid and wet conditions. —Ship all back-ordered items when available. Apply a coat of the water based flux to both pieces, assemble and heat with a torch. We have sent you an email with instructions on how to reset your password. Your password needs to be updated. They also go under the names flush … The surfaces of fitting and tube that overlap to form the joint are known as the faying surfaces. Soldering equipment and materials. ), system working pressures must conform to the allowable limits of annealed tube. Dead soft copper wire is easy to bend, shape and hammer; it is an ideal starting point for forming, shaping and wire-wrapping. BCuP Alloy (pronounced b-cup) - where the B stands for Brazing, Cu is the chemical symbol for Copper, and P is the chemical symbol for Phosphorous.
