CuCrAgFeTiSi alloy is a high conductivity copper based alloy with aging precipitation strengthening, which combines high conductivity and thermal conductivity. It also has unique and excellent hot and cold working performance, high wear resistance, high electroplating performance, resistance to high temperature stress relaxation and electrode ablation. In recent years, it has been gradually applied in connectors such as automotive power assemblies and power battery charging.
