AlloyAlloy SeriesMain featuresΣb Value /MPaWorking temperatures /ºC2214Al-Cu-Mg-SiThe heat treatment can strengthen the aluminum alloy, the main varieties are rod and forgings. The iron impurity content in the alloy composition is lower than that of the 2014 alloy, and the toughness is improved. The strength of solid solution treatment plus artificial aging is higher, and the co - worker has medium plasticity. It is suitable for manufacturing high load parts with thick section. The alloy has high copper content and poor corrosion resistance. Other properties are equivalent to 2014 alloy.
