The Introduction of 2A12 aluminum round bar
2A12 aluminum bar, also known as high-strength duralumin, is a typical duralumin alloy in the AL-Cu-Mg system and can be strengthened by heat treatment. At the same time, its composition is relatively reasonable, and its overall performance is good. It is a hard aluminum material produced in many countries, and its usage is the largest among hard aluminum materials. It has certain heat resistance and can be used as working parts below 150°C. Widely used in aircraft structures, rivets, truck wheels, propeller components, and other structural parts. However, caution is required when using gas and TIG welding because it tends to form intergranular cracks. This alloy has good machinability after cold work hardening, but its corrosion resistance is not high, so anodizing and painting methods are usually required to improve its corrosion resistance.

The Product Features of 2A12 aluminum Round Bar
● High strength: 2A12 aluminum bar has high tensile strength and yield strength, can withstand large loads, and is suitable for manufacturing structural parts that need to withstand heavy objects and pressure.
● Good plasticity: 2A12 aluminum bar has good plasticity before heat treatment and can be used for plastic processing, such as stretching, bending, etc.
● Good corrosion resistance: Compared with other metal materials, aluminum has good corrosion resistance and can resist the erosion of air, water and acid.
● Low density: Aluminum has a low density, which can reduce the weight of structural parts and facilitate transportation and use..
● Good conductivity: Aluminum is a good conductive material and can be used to manufacture structural parts that need to conduct electricity.
