Pure copper is a very ductile metal. For many applications this is an advantage, but not when copper is to be machined. However, the cutting properties of copper can be significantly improved by alloying copper with tellurium. The addition of tellurium has a minimal effect on the thermal and electrical conductivity and ductility of the copper.

The introduction of tellurium to copper has the effect of cutting the chips into short pieces thus enabling a much higher machining speed than is possible with pure copper. As far as machining is concerned, this material can machine up to 4 times the speed of copper and a greater life expectancy is also found on the tooling. Tellurium copper C109 / C14500 / CW118C is suited to those components that require extensive machining.

A typical application is gas cutting nozzles, which involves drilling small holes and swaging to the final shape, electrical applications and various other electrical switches on power semiconductors.
