Chemical composition (mass fraction) % (Cr:0.1-0.8, Zr:0.3-0.6) hardness (hrb78-83) conductivity 43ms/m. Chrome-zirconium copper has good electrical conductivity, thermal conductivity, high hardness, abrasion resistance, explosion resistance, crack resistance and high softening temperature, less electrode loss during welding, welding speed, welding total cost is low, suitable for welding machine electrode related pipe fitting, but electroplated workpiece performance is general.
This product is widely used in automobile, motorcycle, barrel (can) and other machinery manufacturing industry welding, conductive nozzle, switch contact, mold block, welding machine auxiliary device with various materials. Quality requirements
1. Eddy current conductance instrument is used for conductivity measurement. The mean value of the three points measured is 44MS/M
2. Rockwell hardness standard is adopted and the mean value of three points is 78HRB
3. The softening temperature experiment, the temperature of 550 ℃ after two hours, compared with the original hardness after quenching water cooling can not reduce more than 15%
Resistance welding electrodes, chromium zirconium copper through the combination of heat treatment and cold working methods to ensure performance, it can get the best mechanical properties and physical properties, so to do the general purpose of resistance welding electrodes, mainly as a spot welding or seam welding of low carbon steel, coated steel electrodes, can also be used as a mild steel welding electrode rod, shaft and packing material, or as a mild steel welding electrode rod, shaft and packing material, or as a large convex welding machine mould, fixture, stainless steel and heat resistant steel mould or embedded electrodes.
