Tellurium Copper

Tellurium copper is suitable for the turned parts industry. It has a remarkable aptitude for machining parts that require a high electrical and thermal conductivity. This alloy is also suitable for hot stamping.


Applications include welding (plasma nozzle), electrical connections, heating systems, bolts...


Thanks to its high ductility, this alloy exhibits an excellent aptitude for cold working by bending or crimping for example.
