Title
Aluminum Alloy, Hand Forgings and Rolled Rings, 6.3Cu - 0.30Mn - 0.18Zr - 0.10V - 0.06Ti (2219-T852/T851), Solution Heat Treated, Mechanically Stress Relieved, and Precipitation Heat Treated
Scope
This specification covers an aluminum alloy in the form of hand forgings and rolled rings.<p>These products have been used typically for structural parts subject to warpage during machining, but usage is not limited to such applications. Product may be welded in the -T852/-T851 condition but properties are improved by re-heat treatment to -T6 temper after welding.<p>Certain design and fabricating procedures may cause these products to become susceptible to stress-corrosion cracking; ARP 823 recommends practices to minimize such conditions.
Rationale
AMS4144G is a Five Year Review and update of this specification.
