2A12 aluminum sheet is a 2 series AL-CU alloy. It mainly contains alloy component Cu and belongs to the heat treatment alloy plate. So, 2A12 aluminum plate has higher strength after heat treatment.

2A12 aluminum plate has good machinability and spot welding performance. But it is easy to produce intergranular cracks in Gas metal arc welding and argon arc welding. And corrosion resistance is not high. To improve its corrosion resistance,, it needs surface treatment or aluminum plating.

JC Metal China is a 2000 Series Aluminum Sheet Supplier. The main type is 2014,2017,2024,2A11,2A12,2A14 aluminum sheet.

2A12 aluminum sheet Chemical Composition


2A12 Aluminum Plate characteristics

2A12 aluminum alloy plate is a kind of high-strength hard aluminum. It can be strengthened by heat treatment.
When 2A12 aluminum plate is annealed, just quenched and hot, its plasticity is moderate.
Spot welding has good weldability. There is a tendency to form intergranular cracks when using gas welding and argon arc welding.
The machinability of 2A12 aluminum plate is still good after quenching and cold work hardening.
Poor in the annealed state. The corrosion resistance is not high.

Anodizing and painting methods are often used, or the surface is coated with aluminum to improve corrosion resistance.


2A12 aluminum plates are mainly used to make various high-load parts and components. But not stamping forgings. Such as plane skeleton parts, skins, bulkheads, ribs, spars, rivets and other working parts below 150°C.

It is mostly used in molds, transportation vehicles, compressors, rivets, truck wheel hubs, propeller components and various other structural parts.
