AMC4632 ALUMINUM SILICON ALLOY

AMC4632 is a high quality hyper-eutectic aluminum-silicon alloy. It is manufactured by a powder metallurgy route to refine the microstructure and provide enhanced mechanical properties. 

This low density material offers a high tensile modulus (approximately 15% higher than AA4032), good strength and excellent fatigue resistance at ambient and elevated temperatures. It can be used as a replacement for conventional aluminum alloys such as AA4032 and AA2618 in a range of applications.  AMC4632 may be machined to fine surface finish and tolerances using high speed techniques.
