Materion AMC4632 Aluminum Silicon Alloy, T6 (discontinued **)
Categories:	Metal; Nonferrous Metal; Aluminum Alloy
Material Notes:	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 alloy 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. Typical mechanical property data for cold water quenched T6 samples. Information supplied by Materion.
