2219 aluminum round rod block ring cake

In the production of seamless 2A12 T4 aluminum alloy pipe, the production of thick wall pipe accounts for more than 50%. In thick walled pipe production, 2A12 aluminum alloy accounts for more than 60% of its weight, and its use state is basically T4. In most cases, the lower extrusion temperature and higher extrusion speed are adopted to improve the production efficiency. When the Mn content of the alloy is 0.3%-0.6%, the mechanical properties of the alloy can be controlled within a certain range by controlling the extrusion temperature according to the specific requirements of the product.

2A12T4 aluminium alloy plate with variable cross section is widely used in the cantilever structure skin of fighter, trainer, bomber wing, tail and so on. It is an important military aluminium alloy material. The development of aviation industry has accelerated the pace of aircraft renewal, and put forward higher requirements for the quality of 2A12 T4 aluminium alloy variable cross-section plate. Henan chalco aluminium has solved the problem of big wave in the production of variable cross-section sheet by changing the production process, and produced high quality 2A12T4 variable cross-section sheet of aluminium alloy.
