Some Nonferrous Metals Electrode Material
【China Molybdenum Industry News Network】
Advanced Integrated Technologies Inc ( AIT ) supplies RWMA electrode materials used in the resistance welding and reflow soldering industries, including Glidcop and Molybdenum. Our business of manufacturing welding electrodes, reflow soldering thermodes, and hot bars has led us to stock various sizes and quantities of these exotic alloys. Glidcop is an alloy with a minimum mill order close to one thousand dollars. Many companies who wish to make their own electrodes don’t wish to buy that large a quantity of material from the mill. Many electrode compositions are in common use in resistance welding. The choice is usually determined by the materials to be welded. AIT offers an electrode material selection chart at below. Six different electrode compositions are described below and may be ordered from AIT. The user’s selection of welding metals is not restricted, however, to those listed here.
RWMA Class 1, Copper-Zirconium Alloy: suitable for welding aluminum alloys, magnesium alloys, coated materials, brass and bronzes.
RWMA Class 2, Copper-Chromium Alloy: (Glidcop is often substituted for this alloy) This welding metal may be used to weld iron-base, nickel-base, cobalt-base, and chromium-base alloys. Class 2 electrodes are the most versatile general purpose alloys. AIT still builds many class 2 electrodes, but most customers are switching to Glidcop due to its superior qualities.
RWMA Class 3, Copper-Cobalt-Beryllium Alloy: Having the same general applications as the RWMA Class 2 above, this metal sacrifices a small amount of conductivity for increased hardness. The characteristic hardness of Class 3 materials make them desirable for use as electrode-jigs and fixtures in high-production applications.
RWMA Class 11, Copper-Tungsten Alloy: This material is used only as an insert in copper shanks. Generally, this class is used on precious metals and copper-base alloys. If sticking is evident, change to a Molybdenum or Class 13 electrode material.
RWMA Class 13, Tungsten: Also used as an insert in a copper shank, Class 13 metals are used for copper, copper-base alloys and precious metals. The material is difficult to form into special shapes and fractures easily.
RWMA Class 14, Molybdenum Alloys: These are the most popular electrode metals for welding copper-base and other highly conductive alloys. They minimize the sticking often encountered with copper-alloy electrodes.
