C14530 (CuTe0.02Sn0.02) Copper Coil

Short Description:

C14500, or tellurium copper, has similar mechanical properties to unalloyed, pure copper but with a higher machinability. The cutting properties of C14500 are enhanced significantly by creating a copper alloy with the addition of tellurium. Tellurium copper is also known for its high electrical conductivity characteristic.
