Magnesium alloy bars have excellent properties such as low density, high specific strength, good electrical and thermal conductivity, corrosion resistance, beautiful appearance, and easy processing and forming. They are widely used in aviation, aerospace, automotive, construction, electrical, chemical, machinery manufacturing, etc. industry. High-strength magnesium alloy bar is an important structural material indispensable for many military and civil aircraft and transportation vehicles, and has an important strategic position in national defense construction and national economic development.

The corrosion resistance of magnesium alloys to petroleum and alkali substances can be used to manufacture oil pipes and fuel tank parts. When the aircraft works in the marine climate environment, its own materials are required to have good corrosion resistance, and certain measures can be taken to improve the corrosion resistance of magnesium alloys in order to be used in aviation products. In foreign countries, the method of improving the purity of magnesium alloys is mainly used to improve its corrosion resistance. For example, in the United States, by reducing the content of heavy metal impurities copper, nickel and iron in AZ91 magnesium alloys, AZ91D and AZ91E high-purity magnesium alloys have been developed, which can improve the casting performance and improve the corrosion resistance. sex. Experiments show that the corrosion resistance of AZ91E magnesium alloy is close to that of A357 cast aluminum alloy, which is of great significance for expanding the application of magnesium alloy in the aviation field. my country's chemical treatment of the surface of ZM6 magnesium alloy can greatly improve the corrosion resistance, which can be used to manufacture the main box of the helicopter tail reducer and can be used in the marine environment.

With the improvement of the temperature resistance of magnesium alloys, cast rare earth magnesium alloys such as ZM2, ZM3, ZM4, ZM5, ZM6 are widely used in the manufacture of various aircraft engine boxes, transmission boxes and power supply devices. The front and rear casings and the main casing of the domestic Turbojet-7 and Turbojet-13 engines are made of ZM2 magnesium alloy, the front cabin castings of the Turbojet-6 engine of the domestic J-6 aircraft and the centrifugal casing of the Turbojet-11 engine And other parts are made of ZM3 magnesium alloy; the shell of the aircraft hydraulic constant speed device is made of ZM4 magnesium alloy; ZM5 magnesium alloy is used to manufacture the accessory transmission casing and reducer casing of the turboprop engine.
ZM6 cast magnesium alloy has good mechanical properties at room temperature and high temperature, high tensile strength at room temperature and has certain plasticity. The creep strength, lasting strength and instantaneous tensile properties at high temperature below 250 ℃ are better than ZM3 and ZM4 cast magnesium alloys Alloys can be used for parts that work at high temperatures below 250°C for a long time and need to maintain a certain strength, such as the accessory drive rear casing of gas turbine starters.
