Aviation Special AZ31B magnesium alloy

Compared with AZ31B magnesium alloy casting, deformation AZ31B magnesium alloy with higher strength and ductility, as plates, profiles and forging molded parts can be used in various fields of aerospace, automotive, 3C and military, to play its unique advantages . The use of wrought magnesium alloy proportion of small, specific stiffness, high strength ratio, which is widely used in some of the weight of the particularly sensitive hand tools, sports equipment, aerospace, automotive and other fields. The use of lightweight magnesium alloy, vibration, electromagnetic shielding and other fine performance, to make laptops, mobile phones and portable audio equipment such as the housing and other facilities, to achieve lightweight, attractive (metallic) and durable effects. . With the new magnesium alloy and forming process continue to study in depth, purpose and scope of application wrought magnesium alloys will continue to expand. AZ31B magnesium alloy is the lightest metal structural materials of aircraft, spacecraft and missiles used in the manufacturing industry. Magnesium is lighter than aluminum by weight, specific gravity of 1.8, the intensity is low, only 200 to 300 MPa (20 to 30 kg / mm 2), mainly for the manufacture of low load-bearing parts. AZ31B magnesium alloy magnesium alloy castings 3 easily in moist air oxidation and corrosion, and therefore parts before use, the surface needs to be chemically treated or painted. German first production and use of magnesium alloy containing aluminum on the plane. Magnesium alloys have high vibration resistance when subject to impact load can absorb greater energy, as well as good heat performance, so it is an ideal material for the manufacture of aircraft wheel. AZ31B magnesium alloy in gasoline, kerosene, and lubricating oil is very stable, suitable for the manufacture of engine gear casing, pump and tubing, because of the inertia force generated by the rotating and reciprocating motion is used to make a small rocker, flap , doors and control surfaces and other moving parts. Civilian aircraft and aircraft, especially bombers extensive use of magnesium alloy products. For example, B-52 bombers of the body part on the use of magnesium alloy sheet 635 kilograms, 90 kilograms extrusion, casting more than 200 kg. Magnesium alloy is also used in some parts of missiles and satellites, such as China's "Red Flag" air defense missile payload, the tail tank and engine mounts and so the use of magnesium alloys. China is rich in rare earth resources, has developed a magnesium alloy 70s plus yttrium, improve AZ31B magnesium alloy castings 4 room temperature strength, long-term use to 300 ° C, has been applied in the aerospace industry
