Tellurium Copper
Characteristics：
It is a low-alloyed tellurium copper alloy characterized by excellent electrical conductivity and enhanced machinability due to the addition of tellurium and phosphorus. It is widely used in electrical engineering and precision component manufacturing.
Typical applications:
It is mainly used in connector terminals, charging piles, nozzles of plasma cutting machines and power modules of communication base stations for new energy vehicles.
