INQUIRY

3A21 aluminum sheets belong to AL-Mn alloy, which are widely used as anti-rust products. 3A21 aluminum sheets are non-heat treatable, so the mechanical property is improved by cold processing: it has high plasticity at annealed condition, good plasticity when semi-cold hardening, while low plasticity during cold hardening. It has good corrosion resistance, excellent weldability, but poor machinability. It is mainly used on low load parts working in liquid or gas and require high formability and weldability, such as oil tank, gasoline or lubricate pipe, liquid container, and other low load parts made by deep drawing. Wire rods are used to make rivets.

Application:

3A21 aluminum plate can be applied to parts or components that require high formability and corrosion resistance, such as kitchenware, storage units for food or chemical products, troughs or tanks for liquid transportation products, pressure vessels or pipes, cooling fins, make-up boards, photocopier rollers, or ship materials.

Performance：

1) 3A21 aluminum is a typical anti-rust aluminum alloy with excellent corrosion resistance;

2) Good weldability and tensile strength; the elongation property is better than 3003 aluminum ;

3) The surface is smooth, and it can work well under pressure.

Packing & Transportation Details:

1) Interleave paper between each sheet. (Optional for Cold Rolled Sheet).

2) Plate/coil is placed to the iron or wooden pallet, wrapped by water-proof craft paper and fixed by iron belt.

3) Port: Qingdao port or other main ports in China

4) Container: 20ft GP:5898mm (Length)x2352mm (Width)x2393mm (Height), loading 18~25 tons.

40ft GP:12032mm (Length)x2352mm (Width)x2393mm (Height), loading 20~28 tons.
