Sintering Process of Magnets First:Melting The materials are exposed to mid frequency and melted in an induction furnace. Second:Jet Milling After completion of various process steps, the ingots are pulverized into particles that are several microns in size. In order to prevent oxidation from occurring, the small particles are protected by nitrogen. Third:Pressing […]

The Diference between each Peramenent Magnets When purchasing magnets you will see two major types, rare earth or ferrite magnets. Sometimes, under the rare earth magnets, there are sub types like neodymium or samarium. Alnico is another type of magnet you might see listed. Rare earths tend to me more expensive, but why? What’s the […]
Neodymium Magnet Plating and Coating Options The following is a list and description of available coating options for custom magnets. Note: Magnets can only be electro-plated before magnetization. if the plating is compromised after magnetization via abrasion or deliberate machining they cannot be re-plated. Some coatings such as plastic may be done after magnetization, If the […]

Uses Of Neodymium Magnets Neodymium magnets are used for many purposes. They are used in industries, commercially and can even come handy around the house. Neodymium magnets are also used in the Medicine and Health fields for a large number of purposes. Industrial Uses Of Neodymium Magnets Neodymium magnets are often used in machines made […]
Neodymium Magnet Information Neodymium magnets are the strongest permanent magnets commercially available, anywhere in the world. They provide unparalleled levels of magnetism and resistance to demagnetisation when compared to ferrite, alnico and even samarium-cobalt magnets. HISTORY OF NEODYMIUM MAGNETS Neodymium magnets were first developed in 1982 by General Motors and Sumitomo Special Metals following the […]
Neodymium Magnetic Health & Safety Important health & safety information regarding Rare Earth Neodymium Magnets. Liability UMAGNETICS (UMAG) does not accept responsibility for damage that has been caused by the improper handling of magnets. With the purchase of these magnets, you confirm that you have read and understood the following warnings. A health and safety warning […]
Magnetization Direction for Neodymium Magnets Disc neodymium magnets About 95% of our discmagnets are axially magnetized. That is to say the magnetic poles are located on the two circular surfaces Some of our disc magnets are also diametrically agnetized axial diametrical Rod neodymium magnets Usually the magnetization in the rods is by the height. Our rod […]
