2A70 aluminum aluminium tube pipe is a kind of high plasticity, easy forging, stamping and other characteristics.
Material Name: 2A70
Standard: YS/T 439-2001
Characteristics and scope of use of
2A70 aluminum aluminium tube pipe
2A70 aluminum aluminium tube pipe belongs to high strength forged aluminium with high plasticity in hot state, easy forging and stamping;
2A70 aluminum aluminium tube pipe can be strengthened by heat treatment, and its strength after quenching and artificial aging is similar to that of hard aluminium;
2A70 aluminum aluminium tube pipe’s technological performance is good, but it has extrusion effect, so its longitudinal and transverse properties are different;
2A70 aluminum aluminium tube pipe’s corrosion resistance is better, but it has the tendency of intergranular corrosion; its machinability is good, resistance welding, spot welding and seam welding. Good performance, arc welding and gas welding performance is not good.
