C18200 - Zirconium Copper
The C15000 Zirconium Copper is the alloy with high softening temperature, which makes it good welding material. The addition of zirconium increases the strength of alloy and raises its softening temperature. The increased strength and softening temperature makes the alloy suitable for adapters, power semi conductor bases, spot welding electrodes and connectors.
