Haomei GB 2A12 aluminum plate dedicated to the aircraft wing
2A12 aluminum alloy is a kind of high strength hard aluminum, can be heat treatment to strengthen, in the annealing, just quenching and heat plasticity medium, 2A12 aluminum alloy spot welding good welding, gas welding and argon arc welding when the formation of intergranular cracks Propensity; 2A12 aluminum alloy in the quenching and cold hardening can be cut after the performance is still good, in the annealed state bad. Corrosion resistance is not high, often used anodizing treatment and coating method or surface coated with aluminum layer to improve corrosion resistance. Mainly used for the production of various high-load parts and components, such as aircraft on the skeleton parts, skin, frame, ribs, spars, rivets and other working parts below 150 鈩.
Aircraft wings can be made of , the main function of the aircraft wing is to provide lift for the aircraft to support the aircraft flying in the air, but also from a certain stability and manipulation. Ailerons and flaps are generally installed on the wing. The aileron can roll the airplane; the flap can increase the wing lift coefficient. In addition, the engine can also be installed on the wing, landing gear and fuel tank. Wing has a variety of shapes, the number is different. In the early years of low aviation technology in order to provide greater lift, the aircraft to wings or even multi-wing aircraft mainly, but the modern aircraft is generally a monoplane.
Aircraft wing in the overall structure of the aircraft occupies an important role in the use of 2A12 aluminum alloy wing, aluminum alloy low density, reduce the overall weight of the aircraft body, thereby reducing the aircraft's energy consumption; while 2A12 aluminum alloy has a very good Of the anti-corrosion properties, flying in high-altitude atmosphere to a certain extent, reduce atmospheric corrosion, extend the life of the aircraft.
Haomei Aluminum production "1 +1" ultra-wide, ultra-thick aluminum production line, test production of 2-series aluminum alloy has 2011,2014,2017,2A11,2A12, etc., have good mechanical properties, strength processing, small density , Can be used for light structural materials. With "1 + 4" production line and the new production of "1 +1" ultra wide, ultra-thick aluminum production line, Haomei Aluminum 2 Series alloy products will gradually enter the aerospace, automobile manufacturing and other high-tech fields.
