AMC4632
Material Grade:
AMC4632
Material Type:
Aluminium-Silicon Alloy
Description:
AMC4632 is a high quality hyper-eutectic aluminium-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 aluminium 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.
