2014 aluminum sheet belongs to hard aluminum alloy and wrought aluminum alloy from the composition point of the view. 2014 aluminum alloy has good machinability, contact welding, spot welding and seam welding performance is good, arc welding and gas welding performance is poor, can be strengthened by heat treatment, has squeezing effect, the corrosion resistance is not high, and there is tendency of corrosion between inspections during artificial aging.

The chemical composition of aluminum sheet 2014 is:
Al: balance,
Si:0.6 ~ 1.2,
Cu:3.9 ~ 4.8,
Mg:0.40 ~ 0.8,
Zn≤0.30,
Mn:0.40 to 1.0,
Ti≤0.15, Nickel Ni≤0.10,
Fe:0.000～0.700,
The mechanical properties of 2014 aluminium sheet is:
Tensile strength σb (MPa) ≥ 440, elongation δ5 (%) ≥ 10
Aluminium sheet 2014 is applied to applications requiring high strength and hardness including high temperatures. Such as aircraft heavy-duty, forgings, slabs and extruded materials, wheel and structural components and spacecraft parts, truck frame and suspension system parts
