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. [...]

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, [...]
NdFeB Magnet Stripping Operation (Strip Casting), Vacuum strip casting furnace rapidly solidifies NdFeB magnet material to create very small grains Sintered NdFeB magnets manufacture process's Four Step is Strip Casting, also called NdFeB Magnet Stripping Operation Alloyed NdFeB is now ready for melting and strip casting. It is heated in a vacuum furnace and a [...]
