AMPCO® 25 Sand Castings – Premium Hardness & Compressive Strength for High-Performance Dies

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 be avoided and the material should be well backed up.
