Form:

This specification covers an aluminum alloy in the form of extruded bars, rods, wire, profiles, and tubing.

Application:

These products have been used typically for parts requiring good strength where fabrication does not usually involve welding, but usage is not limited to such applications.

Certain design and processing procedures may cause these extrusions to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions.
