145 Copper Product Guide

 

Applications | Mechanical and Chemical Data | Tolerances

 

Overview

Also called Tellurium copper, c145 copper has similar mechanical properties to unalloyed, pure copper but with significantly higher machinability. C145 also maintains good corrosion resistance and excellent electrical conductivity. For hot and cold working, c145 is rated as good, and it can be easily brazed or soldered. Oxyacetylene welding, gas shielded arc welding, and butt welding are just rated at fair. Typically used in high-speed automatic screw machines as well as electrical applications like circuit breaker terminals, hot forged, studs and transformers.

 

Common Trade Names

UNS C14500, CDA 145, C145, ISO CuTeP, Tellurium-Bearing Copper
