Product Details

The core microalloying agent for high-strength, high-conductivity copper alloys. This product is a key additive for developing copper alloys that combine high strength with high electrical conductivity. Zirconium (Zr), through its unique precipitation strengthening effect, can significantly enhance the strength of copper alloys while maintaining excellent electrical conductivity, perfectly solving the technical challenge of the mutual constraint between strength and conductivity in traditional copper alloys.
