Product Details, Specifications, and Technical Information

See Copper Tolerances

Copper Round Bar 145, also called Tellurium Copper, has excellent thermal and electrical conductivity, good corrosion resistance, goor malleability, and excellent machinability. 145 is mechanically similar to pure copper, but significantly easier to machine. It is typically used in high-speed automatic screw machines, circuit breaker terminals, hot forged studs, transformers, and other elextrical components.
