Description

COLDUR-B (CuSi1) is a high copper alloy that is renowned for its combination of strength, corrosion resistance and formability and for its attractive colour. It has a slightly lower silicon content than COLDUR-A®. Known as a high silicon bronze, COLDUR-B is renowned as being one of the easiest of all copper alloys to fabricate - by a wide range of techniques - and is readily formable by both hot and cold methods. It offers excellent forming characteristics combined with an attractive rich, reddish old gold colouration that makes the alloy highly desirable for many architectural and decorative applications. It shows the following features and properties:

Excellent hot and cold formability

High strength properties

Excellent general corrosion resistance

Low magnetic permeability

Attractive reddish old gold colouration
