2A11 T6 aluminum alloy belongs to Al-Cu-Mg series aluminum alloy, is a kind of high strength duralumin, heat treatment can be strengthened, in quenching and hardening state of plasticity medium, spot welding is good, quenching and cold hardening after its machinable performance is good, often using anodic oxidation treatment and paint method or surface coating aluminum layer to improve its corrosion resistance. For common mold, precision parts, fixture, etc. 2A11 T6 duralumin coil is an early application of duralumin, commonly known as standard duralumin. 2A11 T6 aluminum alloy coil belongs to Al-Cu-Mg series aluminum alloy, is a kind of high strength duralumin, heat treatment can be strengthened, in quenching and hardening state of plasticity medium, spot welding is good, after quenching and cold hardening its machinable performance is good, often using anodic oxidation treatment and paint method or surface coating aluminum layer to improve its corrosion resistance.
