Features

High Performance Conductive Spring Material GMX96

NGK Copper-Nickel-Tin alloy "GMX96" is an age hardening type copper alloy, using spinodal decomposition. GMX96 has excellent characteristics such as high strength and heat resistance comparable to beryllium copper alloy, and electrical conductivity equivalent to phosphor bronze. GMX96 is widely used as contact springs in various applications like connectors, switches, etc.

High Performance Heat resistance Material GMX215

NGK Copper-Nickel-Tin alloy "GMX215" is an age hardening type copper alloy, using spinodal decomposition. GMX215 is a high performance heat resistant spring material with high strength comparable to beryllium copper alloy, and the highest level of superior features such as corrosion resistance and heat resistance among conventional copper alloys. GMX215 is a high-performance spring material suitable for parts used in severe condition such as automobiles and industrial equipment.

Features, applications and specifications of GMX96

Features

  • Tensile strength

    GMX96 can achieve a strength of 1,200N/mm2 through age hardening (Spinodal decomposition) and can withstand very high bending stress.

  • Bending formability

    Age hardenable material can be formed into complicated shapes and be heat treated afterwards. Mill-hardened material, which does not require heat-treatment after stamping or forming, has well-balanced performance in strength and formability.

  • Thermal stability

    Due to less stress relaxation at elevated temperature, GMX96 can be used in a wide range of temperature with little loss of mechanical properties and spring performance.

  • Corrosion resistance

    GMX96 has good corrosion resistance and can be used even under severe conditions.

  • Heat distortion

    Due to less deformation (heat distortion) after age hardening treatment, dimensional variance after heat treatment is small.

  • Electrical conductivity

    Electrical conductivity is equivalent to that of phosphor bronze.

Applications

  • Connectors
  • Switches
  • Sockets
  • Ground terminals
  • Motor brushes
  • Jacks
  • EMI shields
  • Watch gears

Features

  • Tensile strength

    GMX215 can achieve a strength of 1,200N/mm2 through age hardening (Spinodal decomposition) and can withstand very high bending stress.

  • Bending formability

    Age hardenable material can be formed into complicated shapes and be heat treated afterwards. Mill-hardened material, which does not require heat-treatment after stamping or forming, has well-balanced performance in strength and formability.

  • Thermal stability

    Due to far less stress relaxation at elevated temperature, GMX215 can be used in wider range of temperature than GMX96 with little loss of mechanical properties.

  • Corrosion resistance

    GMX215 has excellent corrosion resistance and can be used even under severe conditions.

  • Heat distortion

    Due to less deformation (heat distortion) after age hardening treatment, dimensional variance after heat treatment is small.

  • Electrical conductivity

    Electrical conductivity is approximately twice that of stainless steel.

Applications

  • Connectors
  • Switches
  • Sockets
  • Spring washers
