GMX 96 is NGK's high strength copper nickel tin alloy, with excellent resistance to stress relaxation. 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 both families against your specification.<

NGK Berylco alloys go into aerospace, automotive, electronics, telecommunications, energy, defence, medical, hydrogen, home appliances, watchmaking and oil and gas applications. Wherever strength, conductivity and reliability have to work together, these materials earn their place.

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.

Every coil, rod and component is backed by certified systems: ISO 9001, the aerospace standard EN 9100, ISO 14001 and ISO 45001. In-house testing and inspection keep properties consistent from batch to batch.
