AMPCO® M4: High‑Performance Sand‑Cast Alloys with Superior Mechanical Properties

AMPCO® 25 is a patented alloy which displays outstanding mechanical properties. The extreme hardness, linked with an excellent compressive strength and very good friction properties, makes it ideal as a forming and drawing die material. As the elongation of the material is nil, thin sections should

AMPCO® 22 is a duplex structure alloy of approx. 50 % of each phase - gamma 2 and beta. It is remarkable because of its hardness, its excellent compression and wear resistance and by its sliding properties. As the elongation of the material is very low, thin sections should be avoided and the materi

The increase in the Al and Fe content results in a material in which the hard gamma 2 phase (about 400 HB) is present. By proper metallurgical control this hard constituent is uniformly distributed giving this alloy its ability to resist wear.PropertiesGeneralPropertyTemperatureValueDensity23.0 °C7.

The patented process gives AMPCO® M4 mechanical properties beyond the range of commercial nickel-aluminium bronzes, comparable to beryllium copper at a lower cost and without the beryllium copper industrial hygiene requirements.PropertiesGeneralPropertyTemperatureValueDensity23.0 °C7.45 g/cm³Recycle
