2618 and 2618A

Abstract

This datasheet provides information on composition limits, key metallurgy, fabrication characteristics, processing effects on physical, tensile, and creep-rupture properties, and applications of Al-Cu-Mg-Ni alloys 2618 and 2618A. The influence of prolonged holding at elevated temperature on tensile properties and the influence of temperature on compressive yield strength of alloy 2618-T61 hand-forged billets are illustrated.
