Corrosion resistant alloys for hostile environments

For over 50 years we have been building healthy relationships with marine engineers and shipbuilders and have developed a dedicated stock of naval engineering alloys, duplex and superduplex stainless steels. These are supplemented by our own trademark alloys and traditional alloys such as the cupronickels.

All alloys for use in marine applications feature excellent corrosion resistance in offshore environments. They also offer anti-galling properties, high wear resistance and anti-biofouling properties.

Columbia Metals also works closely with major subcontractors to the defence industry to supply numerous grades of copper and nickel alloys.
