Material Properties (T2Y2 Red Copper Contact)
High Electrical and Thermal Conductivity: The copper material of the fuse terminal boasts a conductivity of ≥98%, low oxygen content, and minimal impurities, ensuring stable current conduction.
Excellent Machinability and Weldability: No tendency to hydrogen damage, suitable for machining and brazing in reducing atmospheres.
Alloy Strengthening: A small amount of silver added increases the softening temperature and creep strength while maintaining high electrical conductivity and ductility.
Corrosion and Wear Resistance: Surface electroplating provides protection, enhancing long-term reliability.
Strong Cold Work Hardening: Cold working improves mechanical strength and bending resistance.
These properties ensure the Fuse Terminal Contact maintains long-term stable mechanical and electrical performance in high-load, high-temperature, and high-shock electrical systems.
