Rare-Earth Permanent Magnet in the National Defense and Military Industry 20161105
Neodymium and SmCo Permanent Magnets Manufacturer China Rare Earth Magnet Limited
The Patriot missile is superior to Scud thanks for approximate 4kgs SmCo and neodymium magnets in the guiding system; the supersonic cruise function of Raptor Fighter is dependent on the powerful motor that consists of special rare earth materials; and both the navigation system of Abrams tank and radar of AEGIS system used a great number of
SmCo magnets. From above cases, we can see that how significant of rare earths magnet in the national defense and military industry.
With rare earth
permanent magnet, the performance of armor steel improved about 70%, and the lethality of mortar that consists of rare earths also advanced greatly. In addition, the rare earth elements can also be used in fire-controlled aiming system to be ahead of the enemy in the war. And commonly, the rare earths added in the Night Vision Goggles can strength fighting ability at night.
All of the 17 rare earth elements can be used in this field, such as Thermal Barrier Coating, colored fluorescent material, and PMG. The characteristics of powerful and durable of permanent magnet not only make it available of supersonic flight of plane, but also reduced the weight of it. And the PMG made of Sm-Co and
NdFeB magnets plays a key role for weapon operating. Furthermore, the core components of the new electric engine, including super power built-in Starter, Active magnetic bearing systems, and electrical actuators, are consist of high temperature permanent magnets.
The PMG used in vessel can provide stronger power and lower fuel cost, and as for the submarine, it accomplished the advantages of silence and light. For example, there are more than 2 tons of neodymium iron boron magnets in the advanced hybrid electric drive system of American Destroyers, and more than 1 tons Sm-Co magnets in the Advanced Induction Motors of German Silent Submarine.
In the Attitude control and Orbit control system of satellites and spacecraft, rare earth materials are mainly used in different locking valve. The permanent magnetic valve is light, reliable and energy-saving, which become the core component of propulsion system. Besides, for the ion thruster, the axial magnetic field produced by permanent magnets make ions accelerate, thus to push spacecraft ahead. Therefore, numerous nations have paid high attention to permanent magnets.
What’s more, rare-earth material also plays a great role in precise guidance and electronic control field. Thus, as a whole, rare-earth permanent magnets mean a lot to the development of a country.
