GMX 215's elasticity is greater than copper beryllium alloys, giving springs more working range. NGK Berylco France has been one of Europe's leading high precision processors of beryllium copper strip since 1971, and UK customers are looked after from the NGK Berylco UK office in Salford.

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 you

Electronics designers need spring contacts that stay springy, conduct well and survive millions of cycles. Connectors, switches and relays all depend on materials that keep their contact force, and that's exactly where NGK Berylco alloys are specified.

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.

Quality is not left to chance. NGK Berylco holds ISO 9001, EN 9100 for aerospace, ISO 14001 and ISO 45001, and runs its own testing and inspection laboratory alongside an active R&D programme.
