Form: This specification covers an aluminum alloy in the form of hand forgings and rolled rings. Application: Primarily for structural parts subject to warpage during machining. May be welded in the -T852 condition but properties are improved by re-heat treatment to -T6 temper after welding. Certain design and fabricating procedures may cause these products to be susceptible to stress-corrosion cracking; ARP 823 recommends practices to minimize such conditions.
