2 series aluminum alloy is a heat treatable strengthening alloy. Because of its good comprehensive mechanical properties, it is widely used in aerospace, automobile, military industry and other industries. Typical brands include hard aluminum aa20172024, 2A06 and other alloys on aircraft, of which 2024 alloy can be applied to aircraft skin, rib and other components.
2B06 alloy is an upgraded version of 2A06. By strictly controlling Fe, Si and other impurity elements in the alloy, it has good plasticity, fracture strength and other comprehensive properties. Because of its good hardness under high temperature conditions,
2B06 aluminum plate sheet is a typical heat-resistant structural material, which can be used continuously. When it is heated for 1000 hours at 175 ℃, its tensile strength basically remains unchanged. The cabin seat fuselage bearing parts, such as aviation port frame parts.
Compared with the quasi-static tension of
2B06 aluminum plate sheet, the plasticity of the material is significantly improved, and the maximum increase of elongation is 121%.
Deformation at low strain rate, 2B06 aluminum alloy shows ductile brittle composite fracture. At high strain rate, the size and depth of dimple increase with strain rate, and turn to ductile fracture.
2B06 aluminum plate sheet is widely used for sheet metal parts in aerospace.
