Magnesium is one of the lightest structural metal materials and has the advantages of higher specific strength and specific stiffness, good damping and cutting capacity, and easy to be recycled. Magnesium is added to other elements as a matrix to form an alloy, which is characterized by small density, higher than strength, large elastic modulus, good shock absorbency, high impact load capacity than aluminum alloy, and good corrosion resistance of organic matter and alkali. The main application fields of magnesium alloy are mainly divided into four aspects.
Applications in transportation
With the world energy crisis and environmental pollution, energy saving and light weight have become important problems in the automobile industry. The motorcycle engine, wheel hub, reducer, rear handrail and damping system of magnesium alloy can not only reduce the quality of the vehicle, improve the acceleration and braking performance of the vehicle, but also reduce the vibration, pollutant discharge, noise, and fuel consumption, which can improve the comfort level.
Applications in the electronics industry
Magnesium alloy has excellent properties of thin-wall casting and good ratio strength, stiffness and anti-collision ability, which can fully meet the requirements of high integration, lightness, miniaturization, anti-collision and electromagnetic shielding, heat dissipation and environmental protection requirements of 3C products. At present, the 3C products such as mobile phone, notebook computer, digital camera, camera, PDA and other industries have also set off a boom in the development and application of magnesium alloy shell and parts.
Application in aerospace industry
In terms of aviation materials, structural weight loss and structural bearing and functional integration are important directions for the development of aircraft structure materials. Currently, its applications include components of engines for civil and military aircraft, helices, gearboxes, support structures, and components for rockets, missiles, and satellites.
Applications in chemical fields
The Magnesium alloy sacrificial anode, as one of the effective method of preventing metal corrosion, is widely used in the extended family or industrial water heater, underground iron pipes, cables, Kentucky, oil tank, water distiller, the ship-shell, and the life of the steel pile in the Marine environment.
