CuCrlZr, ASTM C18150 C18200 c18500
Chromium zirconium copper has good electrical conductivity, thermal conductivity, high hardness, wear resistance, explosion resistance, crack resistance and high softening temperature, less electrode loss during welding, fast welding speed, and low total welding cost. It is suitable for use as an electrode for fusion welding machines. For pipe fittings, but for electroplated workpieces, the performance is average.
It has excellent electrical conductivity and good tempering resistance, good uprightness, and the sheet is not easy to bend. It is a very good material processing electrode.

Application: This product is widely used in various materials for welding, contact tip, switch contact, die block, welding machine auxiliary device in automobile, motorcycle, barrel (can) and other machinery manufacturing industries.
