AMC 4632 is a high-quality hypereutectic aluminum-silicon alloy. This alloy is manufactured by a proprietary powder metallurgy method that refines the microstructure and provides enhanced mechanical properties. AMC 4632 is used to replace conventional aluminum alloys such as AA4032 and AA2618 in a range of components from automotive to aerospace. When using this alloy to replace existing materials, it aids in weight reduction and improves stability at elevated temperatures. AMC 4632 is available in billet, forged and extruded forms.
