2A11 aluminum rod bar is a copper-aluminum alloy, one of the earliest types of hard aluminum, commonly known as standard hard aluminum. It has medium strength among the 2000 series aluminum alloys. Its plasticity is still good in annealed, as-quenched, and hot states, and it can be strengthened through heat treatment..

2A11 aluminum bar features
- 2A11 aluminum bar has high strength and good heat resistance, suitable for components operating below 150°C.
- At temperatures above 125°C, 2A11 alloy has higher strength than 7075 alloy.
- The alloy has good formability in hot, annealed, and newly quenched states and can be strengthened through heat treatment, though the process is strict.
- 2A11 aluminum alloy has poor corrosion resistance but can be effectively protected with pure aluminum cladding.
- While welding may cause cracks, it can be welded using special techniques and can also be riveted.
2A11 aluminum bar heat treatment specifications
