Products Introduction
Our Service
2A12 or 2A11 aluminium sheet is a 2 series Al-Cu alloy, which mainly contains the alloy component Cu, and belongs to the heat-treated alloy sheet. Therefore, the 2A12 aluminium alloy strengthened by heat treatment has high strength. And the corrosion resistance is not high, need to carry out surface treatment or aluminium coating to improve its corrosion resistance. Now, 2A12 aluminium sheet is mainly used for making various parts and components with high load (but not including stamping parts and forgings).
