Magnet is not human invention, is a natural magnetite. The ancient Greeks and Chinese people find nature a kind of natural stone magnetized magnet, called "magnet." This stone can magically pick up small pieces of iron, but after swinging freely always point in the same direction. Early sailors put this magnet as its earliest compass to identify the direction of the sea. The earliest discovery and use magnets should be Chinese people, which is the "compass", is one of China's four great inventions. After thousands of years of development, today has become a magnet strong material in our lives. Alloy synthesis by different materials can be achieved with the same effect as the magnet, but also can improve the magnetic force. In the 18th century there have been man-magnet, but the manufacturing process of a stronger magnetic material has been slow until the 1920s to produce aluminum-nickel-cobalt (Alnico). Subsequently, the 1950s produced the ferrite (Ferrite), 70 years to create a rare earth magnets [Rare Earth magnet includes neodymium (NdFeB) and samarium cobalt (SmCo)]. Thus, magnetic technology has been rapid development toys with magnets, magnetic materials also makes components more compact metal alloy magnets include neodymium magnets Nd2Fe14B magnet), samarium cobalt magnets (SmCo magnet), Alnico magnets (ALNiCO magnet) iron-chromium cobalt magnets (FeCrCo magnet) sintered iron boron Ru: was developed in 1983 after a new permanent magnet material, it has a very high magnetic properties, is widely used in a variety of permanent magnet motor, engineering machinery, electro-acoustic, appliances and medical devices. Sintered SmCo permanent magnetic material is a superior tool magnet that has a high magnetic measurements, and also a strong anti-corrosion, oxidation resistance, low temperature coefficient, high Curie temperature, in a relatively high environments, are widely used in motors, sensors, detectors, radar and other high-tech fields. Alnico suitable for the production of complex shape. Light, thin, small products, widely used in instrumentation, communications, magnetic switches and various sensors. Iron-chromium cobalt magnets (FeCrCo magnet) is a permanent magnet in the Transformers, the most deformable permanent magnet alloy can drawing (0.2-0.3mm) trombone strip and various mechanical processing. A.FeCrCo (Fe-Cr-Co) distortion permanent magnetic alloy with high magnetic AlNiCo permanent magnetic alloy with comparable, but it contains about 50% Co amount lower than the AlNiCo. B.FeCrCo alloys have excellent ductility and ease of processing plastic magnet, which is a permanent magnet alloy casting unmatched features, and a higher operating temperature of the alloy is about 400, and is not, and NdFeB rare earth permanent magnets. C.FeCrCo alloy processing can be made by adding wire, rods, tubes, and forgings lighting with magnets, by turning, milling, planing, drilling and punching and other machining, can be made into a variety of complex shape of the permanent magnet elements, In particular, small, long thin element exhibits unique characteristics. Thinnest strip can reach 0.05mm, the finest silk material can be processed into the 0.1mm.
