In the field of the arms industry
Magnesium alloy reduces the quality of weapons and equipment, realizes the lightweight of weapons and equipment, and is the ideal structural material to improve the tactical performance of weapons and equipment. Magnesium alloy military applications in the past is mainly in the field of aviation, in recent years, magnesium alloy and magnesium-based composite materials have been gradually in the weapons and ammunition on the successful application, the development is very rapid.
(1) The use of magnesium alloy and magnesium-based composite materials to replace the weapons and equipment of medium and low strength requirements of aluminum alloy parts and some ferrous metal parts, to achieve lightweight weapons and equipment.
(2) Substitute engineering plastics to solve the problem of aging, deformation and discoloration of parts. At present, light weapons, optoelectronic and communication equipment products, combat vehicle instrument panels, etc. are made of engineering plastics. Engineering plastics, especially fiber-reinforced plastics, have the highest specific strength, but the modulus of elasticity is small, the specific stiffness is much smaller than magnesium alloy, and it is difficult to recycle, poor environmental adaptability, easy to wear and aging deformation and discoloration, which affects the tactical performance of the weapon, but also affects the appearance of the weapon. This kind of parts using magnesium alloy and magnesium-based composite materials can fundamentally overcome these defects of engineering plastics.
(3) The magnesium alloy of missile and other aircraft parts. In the past, magnesium alloy has been used less in missiles, and only magnesium powder is used in flares. Magnesium alloy due to low density, in recent years in missiles, rockets and other structural components are widely used, mainly for tactical air defense missiles, the support cabin section and aileron skin, wall plate, strengthen the frame, rudder surface, spacer frame and other parts, the material for MB2, MB3, MB8 deformation of magnesium alloy. ZM5 magnesium alloy is used on the satellite to make tic-tac-toe beams and camera frame, as well as a variety of instrument brackets and shells, etc..
(4) The research and development of new magnesium alloy materials has promoted the magnesiumization of weapon parts. In recent years, the newly developed heat-resistant, wear-resistant, ultra-light (Mg-Li) and other new magnesium alloys and magnesium-based composite materials, as a result of a series of special properties, accelerated the magnesium alloying of weapon parts.
Nuclear industry
Metallurgical industry
By far the largest application area for magnesium is as an alloying element in aluminum alloys to improve strength and corrosion resistance. Aluminum-magnesium alloys are both light and hard, have good corrosion resistance, are weldable, and can be surface-treated, making them an important material in the manufacture of airplanes, rockets, speedboats, vehicles, and so on. In addition, magnesium is added to zinc die casting alloys to increase their strength and improve dimensional stability. Magnesium is also an important chemical component in other zinc products such as roofing sheets, photo-etched sheets, dry cell battery shells, and anodized pool structures. Magnesium is also used as an alloying element in nickel-based alloys, nickel-copper alloys, and nickel-copper-zinc alloys to improve the properties of the alloyed materials.
