Extruded Magnesium alloy Billet WE43C T5 with high strength rare earth metal Y Nd

Magnesium alloys are mixtures of magnesium with other metals (called an alloy), often aluminum, zinc, manganese, silicon, copper, rare earths and zirconium. Magnesium is the lightest structural metal. Magnesium alloys have a hexagonal lattice structure, which affects the fundamental properties of these alloys. Plastic deformation of the hexagonal lattice is more complicated than in cubic latticed metals like aluminum, copper and steel. Therefore magnesium alloys are typically used as cast alloys, but research of wrought alloys has been more extensive since 2003. Cast magnesium alloys are used for many components of modern cars, and magnesium block engines have been used in some high-performance vehicles; die-cast magnesium is also used for camera bodies and components in lenses.

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.

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.
