A copper alloy for harsh environments must resist heat, corrosion and wear together. Copper nickel tin was developed for exactly these demands. With more than 50 years in high performance copper alloys, NGK Berylco supplies UK, Irish and Nordic customers through its Salford office, backed by the wider NGK Group.

NGK Berylco's GMX copper-nickel-tin range is a family of beryllium-free alloys built for demanding specifications on temperature resistance, friction and corrosion. Grades include GMX 96 (C72700), GMX 215 (C72950) and GMX 158 (C72900), supplied as strip and as rod and wire.

Copper-nickel-tin is worth a look when a design needs strength and heat resistance but conductivity is less critical, or when a beryllium-free material is preferred. For high current contacts, beryllium copper still leads. For springs that run hot, bearings and bushings, and parts exposed to friction and corrosion, the GMX grades often come out on top. NGK Berylco can compare b

Oil and gas sites bring corrosive fluids, high loads and explosive atmospheres. Non-sparking, non-magnetic and corrosion resistant copper alloys are a sensible choice for tools and components used in these hazardous environments.

GMX 96 offers very high mechanical strength and excellent resistance to stress relaxation. GMX 215, an NGK exclusive, brings thermal stability and heat resistance above 200 °C, with elasticity that exceeds copper-beryllium alloys. Across the range, the alloys combine mechanical strength, thermal stability, corrosion resistance and friction performance, though electrical conductivity is lower than the Berylco beryllium copper grades.

NGK Berylco also runs a scrap recycling and buyback programme. Recovered material is remelted into alloy of identical composition, which cuts waste and helps customers hit their sustainability targets. All of this sits under ISO 9001, EN 9100, ISO 14001 and ISO 45001.
