Characteristics of 2A12 aluminum tube
High strength and hardness: After heat treatment, the strength of 2A12 aluminum tube can reach more than 470MPa.
Strong heat resistance: Suitable for use in working environments up to 150℃.
Good weldability: 2A12 alloy has excellent spot welding and seam welding performance, which is very suitable for the manufacture of complex structural parts.
Poor corrosion resistance: Due to the weak corrosion resistance of 2A12 aluminum, users must perform anodizing or other anti-corrosion treatment when using it outdoors or in humid environments.
Poor processability: In the annealed state, the material has low processability and requires the use of specific cutting tools and processes.
Application of 2A12 aluminum tube
Aerospace: 2A12 aluminum tube has high strength, toughness and corrosion resistance. It is widely used in the aerospace field to manufacture aircraft structural parts, fuel tanks, wings and other key components. For similar high-performance options, you can also explore our 2024 aluminum tube and 7075 aluminum tube, both known for their excellent fatigue resistance and strength-to-weight ratio.
Automobile Manufacturing: 2A12 aluminum alloy is also used in the automotive field for body structures, chassis parts and engine components to achieve lightweight vehicles. For enhanced corrosion resistance or better extrusion formability, consider 6061 aluminum tube or 7005 aluminum tube.
Shipping and Railways: Commonly used in large molds, mechanical parts, and pressure vessels. If your project requires higher corrosion resistance in marine environments, 5083 aluminum tube is a preferred marine-grade option.
Sports Equipment: Thanks to its lightweight and high strength, 2A12 is widely applied in sports equipment like bicycle frames, golf clubs, and skis. Depending on the shaping complexity or required hardness, alternatives such as 6063 aluminum tube and 2A14 aluminum tube may also be suitable.
