AMZIRC
AMZIRC is oxygen free copper plus zirconium.
It is an excellent resistance welding material with very high softening temperatures. A small addition of zirconium to copper improves resistance to softening and resists deformation at high temperatures where normal copper would soften rapidly. AMZIRC is used as an RWMA Class 1 electrode material to minimize sticking when resistance spot welding galvanized or coated materials.

NOTE: AMZIRC, C15000 Copper Zirconium and C18150 Copper Chromium Zirconium are both good replacements for C16200 Copper Cadmium. AMZIRC, C15000 Copper Zirconium is a good replacement because of its excellent thermal and electrical conductivity while offering moderate strength. AMZIRC strength properties are developed through cold working (similar to C16200) whereas C18150 strength properties are developed primarily from heat treating (precipitation hardening), which is an advantage for large parts.
