Aluminum Alloy 2219 block plate

The Aluminum Alloy 2219 block plate belongs to the heat-treatable-strengthened deformed aluminum alloy. After the solution aging treatment, the mechanical properties of the aluminum alloy are greatly improved, and the plastic deformation is accompanied by the deformation and strengthening of the aluminum alloy. It has the characteristics of high strength, good low temperature and high temperature mechanical properties, high fracture toughness, and good stress corrosion resistance.

Application of Aluminum Alloy 2219 block plate
In my country, the Aluminum Alloy 2219 block plate are mainly used in the production of the melon structure of the space rocket fuel storage tank. The melon parts are mainly formed by drawing large aluminum alloy sheets.
