Aluminum Alloy, Extrusions 4.4Cu - 1.5Mg - 0.60Mn (2024-T8511) Solution Heat Treated, Cold Worked, Stress-Relieved by Stretching, Precipitation Heat Treated, and Straightened
|Publication Date:||1 January 2019|
This specification covers an aluminum alloy in the form of extruded bars, rods, wire, profiles, and tubing produced with cross sectional area of 32 in2 (206 cm2) maximum.
When no Type is specified, Type I shall apply.
These extrusions have been used typically for parts subject to excessive warpage during machining due to residual stresses and for parts requiring high strength and whose fabrication does not normally involve welding, but usage is not limited to such applications
Certain processing procedures may cause these extrusions to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions.
