2A70 aluminum alloy is an aluminum alloy with high plasticity, easy forging and punching.
Features and scope of application:
High-strength forged aluminum has high plasticity in hot state and is easy to forge. Stamping; it can be strengthened by heat treatment, and its strength after quenching and artificial aging is similar to that of hard aluminum; process performance
Good, but there is squeezing effect, so the longitudinal and lateral properties are different; the corrosion resistance is better, but there is a tendency of intergranular corrosion; good machinability, resistance welding, spot welding, seam welding
Good performance, poor arc welding and gas welding performance.
2A70 aluminum forged ring is used to manufacture internal combustion engine pistons, and complex forgings that work at 200-250°C, such as compressor impellers, blower impellers, etc.; plates can be used for structural parts at the above temperature, and its use is more heat-resistant than another Forged aluminum 2A80 is more extensive.
