Abstract

Alcoa EverCast (C862F) is a proprietary, heat-treatable, Al-Zn-Mg-Cu casting alloy (7xx.x series) that also contains small amounts of vanadium and zirconium. Compared with conventional 3xx.x alloys, 7xx.x alloys eliminate brittle silicon particles thus allowing for the highest fatigue strength. The result is significantly higher tensile and fatigue strengths compared to the traditional A356 alloy with properties equal to or better than most 6xxx alloy forgings. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fatigue. It also includes information on corrosion resistance as well as casting. Filing Code: Al-471. Producer or source: Alcoa Corporation.
