The 2A11 aluminum bar is a high-strength, easy-to-machine, medium-strength alloy bar widely used in aerospace, precision components, structural parts, and mechanical applications. It belongs to the 2000 series aluminum alloys, known for good plasticity in hot and annealed states and the ability to be strengthened through heat treatment.
2A11 Aluminum Bar
The 2A11 aluminum bar is a high-strength, easy-to-machine, medium-strength alloy bar widely used in aerospace, precision components, structural parts, and mechanical applications. It belongs to the 2000 series aluminum alloys, known for good plasticity in hot and annealed states and the ability to be strengthened through heat treatment.
This alloy’s combination of strength, machinability, and heat treatability makes it ideal for parts where load-bearing performance and dimensional precision are essential. Typical applications include frames, rivets, fasteners, shafts, structural fittings, and other aerospace or automotive components.
