Since 2002 , focus on manufacturing and supplying various kinds of bonded ferrite magnets

     

The long history of the magnet

Magnets found in a long time ago, the ancient greeks and Chinese nature, there are a variety of natural stone, magnetization is called 'tool'. This stone can be magic little pieces of iron absorption, and at a random wobble is always point to the same direction. Early voyager the magnet as the compass of its first to identify the direction in the sea. After one thousand years of development, the magnet has become indispensable in our life today strong material. Through the synthesis of different material alloy can also achieve the same effect as the tool, but also can improve magnetic force. As early as the 18th century has seen artificial magnet, but the process of making stronger magnetic material is very slow, until the 1920 s produced aluminum nickel and cobalt. Then, in the 1950 s and created a ferrite, successively make rare earth magnets in the 70 s. At this point, magnetism obtained the rapid development of science and technology, strong magnetic material also makes the components more miniaturization.
