Product Code:SAE AMS4248
Title:Aluminum Alloy, Hand Forgings and Rolled Rings 1.0mg 0.60si 0.28cu 0.20cr Solution Heat Treated, Stress Relief By Compression, and Precipitation Heat Treated
Issuing Committee:Ams D Nonferrous Alloys Committee
Scope:This specification covers an aluminum alloy in the form of hand forgings and rolled rings procured to inch/pound units. These products have been used typically for complex shaped parts requiring moderate strength and good forgeability of the alloy and where stability is required during machining, but usage is not limited to such applications. Corrosion resistance of this alloy is superior to that of aluminum alloys having copper as the principal alloying element.【英文标准名称】:StandardSpecificationforSteelWire,HardDrawnforPrestressingConcretePipe
