Permanent Magnet Stability The ability of a permanent magnet to support an external magnetic field results from small magnetic domains “locked” in position by crystal anisotropy within the magnet material. Once established by initial magnetization, these positions are held until acted upon by forces exceeding those that lock the domains. The energy required to disturb [...]
Briefing of Rare Earth Magnet Materials Price in 42 Weeks 2019 1. Briefing of Important News This week, the prices of PrNd, DyFe and Tb fell slightly.

In order to conscientiously implement the national and provincial requirements [...]
Permanent Magnet Materials Permanent magnet lodestones contain magnetite, a hard, crystalline iron ferrite mineral that derives its magnetism from the effect the earth's magnetic field has on it. Various steel alloys can also be magnetized. The first big step in developing more effective permanent magnet materials came in the 1930s with the development of Alnico [...]

Magnetrons Magnetic Assemblies, Sputtering magnetrons magnet materials, magnetic designs, FAQ 1, Help us designs Magnetrons Magnetic Assemblies - We do not make Magnetrons; we make the magnetic assemblies that enable these devices to operate effectively. In order to make a perfect magnet assembly, we would need to know the following: 1. What Type of magnetron is required? [...]
Sintered Ferrite magnet (Ceramic Magnets, Hard Ferrite Magnet) were developed in the 1960's as a low cost alternative to metallic magnets. Even though they exhibit low energy (compared with other permanent magnet materials) and are relatively brittle and hard, Sintered Ferrite magnet (ceramic magnets, Hard ferrite magnet) have won wide acceptance due to their good [...]
NdFeB Magnets Environmental Protection NdFeB magnets are generally divided into bonded NdFeB and sintered NdFeB. Bonding is actually injection molding. Sintering is vacuum forming through high temperature heating. It can be processed into different types according to various requirements. NdFeB Magnets Environmental Protection The advantages of neodymium-iron-boron magnets are their high performance-to-price ratio [...]
