What is neodymium magnetism?

Neodymium magnet was invented by Akihito Sagawa of Sumitomo Special Metals Company in 1982. It is mainly composed of neodymium, iron, boron and other chemical elements.

Neodymium magnet is the magnet with the highest commercial performance found at present, and it is called the magnetic king. It is extremely magnetic, and its maximum magnetic energy product is more than 10 times higher than that of ferrite. Its machinability is strong. The working temperature can reach up to 200 degrees Celsius. Hard texture, stable performance, good cost performance and extremely wide application. Neodymium magnet has strong chemical activity, so its surface must be coated.

Production technology: batching, smelting, ingot making/belt throwing, crushing, pressing, sintering and tempering, magnetic detection, grinding, pin cutting, electroplating and finished products.

Application: It is possible to replace the traditional pure ferromagnet, Al-Ni-Co alloy and Sm-Co magnet in many fields, such as motors, instruments, automobile industry, petrochemical industry, magnetic health care products and so on. Produce magnets of various shapes, such as disc magnets, ring magnets, rectangular magnets, arc magnets and other magnets.
