Tellurium Copper C14500 Machining
Tellurium Copper C14500 Machined Parts
Sunhy has a reputation for machining quality parts from Tellurium copper alloy 145. We can machine intricate parts on our CNC Swiss machines and CNC turning centers.
Tellurium copper alloy 145 (TeCu) is considered a free-machining copper alloy, ideal for parts that require extensive machining, corrosion resistance, or high conductivity. It produces short, clean chips that are easily removable. Tellurium copper machines more quickly and efficiently than pure copper.
TeCu has a machining cost factor of 0.8 when compared to steel 12L14. It is good for hot and cold working, forging, brazing, and soldering, but is not ideal for welding. TeCu can be annealed.
