Model 2A12 -Aluminum Rod

High strength duralumin, can be strengthened by heat treatment, can be welded. 2A12 aluminum alloy belongs to Al-Cu-Mg series aluminum alloy, main features and application: This is a kind of high strength duralumin, can be strengthened by heat treatment, in the quenching and hardening state of plasticity, spot welding is good, with gas welding has a tendency to form intercrystal cracks, the alloy after quenching and cold hardening its machinability is good, after annealing machinability is low: Corrosion resistance is not high, often using anodic oxidation treatment and painting method or surface coated with aluminum layer to improve its corrosion resistance.
