Form: This specification covers two tempers of aluminum alloy in the form of bars@ rods@ and wire. Application: Primarily for parts requiring good strength and whose fabrication does not involve welding. Certain design and processing procedures may cause these products to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions.
