Zinc and Nickel Coating Magnet in Hardness, Life and Price The most commonly used coatings for NdFeB magnets are galvanized and nickel-plated. They have obvious differences in appearance, corrosion resistance, service life, price, etc. The following are the key points. Polishing difference: Nickel plating is superior to galvanizing in polishing, and the appearance is brighter. [...]
Magnetic Coatings Samarium Cobalt, Alnico, and Ceramic materials are corrosion resistant and do not require to be coated against corrosion. Alnico is easily plated for cosmetic qualities and Ceramics may be coated to seal the surface which will otherwise be covered by a thin film of ferrite powder. NdFeB magnets, both sintered and bonded, are [...]
Neodymium Magnet Plating & Coating Neodymium magnets are much more susceptible to corrosion than Ceramic, Samarium Cobalt and Alnico, and would need to be coated and protected, particularly in harsh settings. They can be easily oxidized if exposed to air and moisture in atmosphere, and would become structurally vulnerable leading to breakage. To prevent this, [...]
Diamagnetic Levitation, Magnetic Levitation- Everyone is familiar with magnets that attract ferrous objects like iron and your fridge. A steel nail will be attracted to a magnet. But what is less known is that there are materials that are REPELLED by a magnetic field. In fact, almost everything is diamagnetic. The only reason you don't [...]
