Prodsuct Introdsuction


2A11 aluminum alloy sheet sheet Al-Cu-Mg Aluminum Alloy, is a kind of high strength aluminum alloy, heat treatment can be strengthened, and just in quenching hardened state plastic medium, spot welding, quenching, and cold hardening after the cutting performance are good, in order to improve the corrosion resistance of anodic oxidation treatment and ordinary painting method or with the aluminum surface layer, as the common military use of aluminum and aluminum aerospace.

Prodsuct Features


2A11 aluminum sheet is one of the earliest duralumin, generally called standard duralumin, with medium strength, good plasticity in annealed, freshly quenched and hot state, heat treatment strengthening, used in the quenched and natural aging state, spot welding Good performance, there is a tendency to crack when 2A11 is used as solder for gas welding and argon arc welding; the aluminum-clad sheet has good stability, and the corrosion resistance is not high when the aluminum is not clad, and there is a tendency to prodsuce intergranular corrosion when heated over 100℃.
