2A70 aluminum aluminium round bar rod for aircraft skeleton

2A70 is AlCuMg aluminum alloy, which is high-strength wrought aluminum with high plasticity in the hot state, easy forging. Stamping; heat treatment strengthening, similar strength to hard aluminum after quenching and artificial aging; good process performance, but crowded The pressure effect, so the longitudinal and lateral properties are different; the corrosion resistance is good, but there is a tendency of intergranular corrosion; the machinability is good, the resistance welding, the spot welding, the seam welding performance is good, the arc welding and the gas welding performance are not good. Poor in the annealed state. The corrosion resistance is not high, and the anodizing treatment and painting method or the surface is coated with an aluminum layer to improve the corrosion resistance.

 
Application:
 
2A70 aluminum aluminium round bar rod is mainly used for making various high-load parts and components (but not including stampings forgings) such as skeleton parts, skins, partitions, ribs, spars, rivets, etc. . With the development of the civil industry, 2A70 aluminum round bar has also been applied to various types of machining, machine tools, automobiles, construction and other industries with high plasticity, easy to forging, punching and so on.
