7175 aluminum forged block ring bar cake
2A12 alloy is a heat-treatable and hardening alloy. It has high strength and plasticity in natural aging and artificial failure. It has been widely used in aircraft manufacturing. It can be processed into various semi-finished products, such as 2A12 Aviation aircraft aluminum sheet
, 2A12 Aviation aircraft aluminum plate, variable cross-section plate, pre-stretched 2A12 Aviation aircraft aluminum plate sheet, various profiles and bars, pipes, etc. Forgings and die forgings. Since 1957, Chalco aluminum has successfully manufactured various types of aircraft's main mechanical components with this alloy, such as skins, baffles, wing beams, skeleton parts and so on, as well as some non-main mechanical components. With the development of the aviation industry, the alloy products are also increasing. In order to meet the needs of new types of machines, thin sheets and profiles in the state of artificial aging, and thick sheets with partial specifications to eliminate stress, have been developed and installed successfully.
The alloy has short mechanical properties and stress corrosion resistance. Artificial ageing is generally recommended for products with δ> 6.4 mm, as high temperature ageing helps to eliminate residual stress during quenching. In addition, stable heat treatment (T7) should be used for parts that must be precisely fitted at long-term high temperatures.
