Description

2.1291 (CuCr) is a copper chromium alloy with the outstanding electrical and heat transfer properties of copper but without the drawbacks of being soft and ductile. The addition of a small amount of chromium ensures its high strength, especially after suitable heat treatment that achieves its good mechanical properties. It shows the following features and properties:

High electrical conductivity

High thermal conductivity

High strength

Resistance to softening at elevated temperatures
