Description

  • Maximise tool speed and product quality.
  • Improve sliding properties.
  • Reduce production cost.
  • Minimum friction.
  • No seizing or scratching.

Through our patented production process, AMPCO® M4 has mechanical properties far beyond the range of conventional commercial nickel-aluminium bronzes. The increase in the Al and Fe content in the alloy results in a material in which the hard gamma 2 phase is present. By expert metallurgical control, this hard constituent is uniformly distributed giving the alloy its unique performance qualities and the ability to resist wear.

Best used

For higher technical properties at elevated temperatures, with corrosion-resistant properties.

Ideally suited for

Aircraft landing gear bearings and bushings, being dies (shoes and mandrels) for the tube bending industry, gear wheels and wear/guide planes.
