2014A
Grade 2014A aluminium is a heat treatable high strength alloy with a 4-5% copper addition. Produced in bar and profile it is supplied in the fully heat-treated condition for the optimum mechanical properties.
Normally stocked in the T6 condition (stress relieved and artificially aged) the2014A offers a high strength vs. density and is commonly used in the aerospace and defence industries for the manufacture of aircraft structures, and truck frames. The general resistance to atmospheric attack is low, especially in marine environments. To improve the resistance against corrosion 2014A can be hard or protective anodised, coated or if in storage, lightly coat with Lanolin based protective Oil.
