Aluminum Alloy Die Forgings, 4.0Cu – 2.0Ni – 0.68Mg (2018-T61), Solution and Precipitation Heat Treated (Noncurrent: Aug 2009)
SAE International , 08/05/2009
This specification has been declared NONCURRENT by the Aerospace Materials Division, SAE, as of August 2009. It is recommended, therefore, that this specification not be specified for new designs. NONCURRENT refers to those materials which may have been widely used previously and which may be required for production or processing of existing designs in the future. The Aerospace Materials Division, however, does not recommend these specifications for future use in new designs.
This specification covers an aluminum alloy in the form of die forgings and forging stock.
This product has been used typically for parts for aircraft engines, but usage is not limited to such applications.
Certain design and processing procedures may cause these forgings to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions.
