TROJAN is Columbia Metals’ ultimate super-strength copper nickel silicon alloy, specially developed to provide a unique blend of mechanical 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.

The alloy exhibits a remarkable blend of properties, characterised by superior strength coupled with good ductility and excellent wear and galling resistance. It also possesses good thermal and electrical conductivities and excellent corrosion resistance in many environments.

As with its sister alloy COLSIBRO, TROJAN is readily machinable and finds use in a similar range of high-performance automotive and motorsport applications that require superior mechanical properties.
