Tellurium copper, also known as telco or telco copper is frequently used in products and applications that require a high electrical conductivity and a high machinability. The copper makes it fairly easy to machine. As a result, the material is used in electrical discharge machining applications, especially when an electrode requires a higher electrical conductivity than the workpiece. Tellurium copper is also frequently used in soldering applications, brazing applications and a select number of welding applications.
