China leading magnesium alloys, aluminum titanium alloys, aluminum titanium boron, aluminum strontium alloys manufacturer NJYH Rare earth magnesium alloys produced by are used in aerospace, automotive, electronics and other fields.
The performance advantages of rare earth magnesium alloys are mainly reflected in high temperature resistance and high strength. By alloying with rare earth elements, the strength and heat resistance temperature of magnesium alloys can be significantly improved. Abroad heat-resistant rare earth magnesium alloys have been applied to aircraft skins, missile cabins, satellite space structural parts, spacecraft frames, engine hoods, engine cylinder blocks and gearbox shells. With the social and economic development, there has been greater expansion in the military and civilian fields.
At present, magnesium alloys are mainly used in non-load-bearing or sub-bearing parts of weaponry. With the improvement of magnesium alloy strength, heat resistance and corrosion resistance, the exploration of the application of magnesium alloy engine box, medium and high speed missile cabin, airborne equipment and individual weapons and other important structural parts has begun, and efforts have been made to weapon equipment Transition of main bearing structure.
Magnesium alloy is an ideal structural material for reducing the quality of weapons and equipment, realizing the lightweighting of weapons and equipment, and improving the performance of weapons and equipment. The needs of weapons and equipment have promoted the development of high-performance magnesium alloy materials and application technology development. In the military industry, ZM6 cast magnesium alloy with rare earth metal neodymium as the main added element has been used in important parts such as helicopter reducer cases, fighter ribs and rotor lead pressure plates for 30kw generators. With the progress of smelting and processing technology, the price The reduction in the weight of weapons and equipment is increasing, and the demand for magnesium alloys in weaponry is increasing.
In order to reduce the weight of weapons and equipment, on the one hand, we must fully tap the potential of lightweighting of existing materials from the perspective of integration of design and materials. On the other hand, from a development perspective, we must actively explore the lightweight characteristics of new materials and grasp New material development provides opportunities for lightweighting. Therefore, my country's aerospace, defense and military industry, rail transportation, automobiles and other fields have put forward urgent requirements for lightweight materials. As far as aircraft are concerned, the economic benefits and performance improvements brought by lightweight materials are very significant. Experts point out that the fuel cost savings of reducing the same weight of commercial aircraft and automobiles are nearly a hundred times that of the latter, while the fuel cost savings of fighter jets are nearly ten times that of commercial aircraft, and more importantly, the improvement of their maneuverability can be extremely It is of strategic importance to greatly improve its combat effectiveness and survivability. Experimental research proves that for every 1g weight loss of the spacecraft, it can save 4kg of launch fuel, and the economic benefit of reducing the weight of the aircraft by 1 pound; commercial aircraft is $ 300, fighter aircraft is $ 3,000, and spacecraft is $ 30,000.
The materials used in aerospace and weaponry are in harsh working conditions and often need to serve in harsh environments such as vibration, sand, corrosion, and high temperature. This is the rare earth magnesium alloys such as WE43, WE54 are widely used in new aero engine gearboxes and In the helicopter's variable speed system, such as a company's S-92 helicopter and Bell BA-609 tilt rotor aircraft and the European NH90 helicopter.
Magnesium alloys are widely used in the manufacture of aircraft components, such as engine components, seats, pedals, landing gear, aircraft cabin frames, turbojet engine covers, and various radio equipment bases. From the perspective of medium- and long-term development, the weight reduction of weapons and equipment in the world is the main driving force for the application research and development of lightweight structural materials such as magnesium alloys. Research and development of high-strength and high-toughness magnesium alloys, heat-resistant magnesium alloys and their surface protection technologies and The future development trend of lightweight weapons and equipment is consistent, and the development and application of high-performance magnesium alloy materials in the field of defense and military industry is irreversible.
