AMPCO® 22 Sand-Cast Duplex Alloy: Superior Hardness & Wear Resistance

Sand casting is a metal forming process in which a mold is first formed from a three-dimensional pattern of sand, and molten metal is poured into the mold cavity for solidification. As part of the process, castings may undergo a series of heating and cooling processes to ensure they meet th

AMPCO® 26 is a patented hard grade aluminium bronze. Its exceptional hardness makes it a unique material. However, this extreme hardness means fragility and machinability difficulties. This alloy has very limited uses and machinability, but it gives exceptional results.PropertiesGeneralPropertyTempe

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

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.
