Description

2.0857 (CuNi3Si) ultimate super strength copper nickel silicon alloy, specially developed to provide a unique blend of mechnical and physical properties for high performance engineering. It has similar characteristics to Colsibro®, although Trojan is produced with increased levels of nickel and silicon in order to further increase the mechanical strength. It shows the following features and properties:

Ultra-high strength

High electrical and thermal conductivity

Excellent wear and galling resistance

Extremely low magnetic permeability

Excellent general corrosion resistance

Outstanding bearing properties

Spark resistance

Good machinability and dimensional stability

Outstanding low temperature mechanical properties
