Title:Aluminum Alloy, Discontinuously Reinforced Sheet 2009/Sic/15w (T8p) Solution Heat Treated, Stretched, and Precipitation Heat Treated
Issuing Committee:Ams D Nonferrous Alloys Committee
Scope:This specification covers discontinuously reinforced aluminum alloy (DRA) metal matrix composites (MMC) in the form of sheet. This sheet has been used typically for structural applications requiring high static strength, moderate fatigue strength, and high elastic modulus, but usage is not limited to such applications.
