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, [...]
Humid Environment Magnet Coatings In high humidity atmospheric conditions, standard nickel-coated Neodymium magnets will eventually succumb to corrosion and over time will stop performing at an acceptable level. Ferrite or Samarium Cobalt magnets may be viable alternatives. Ferrites and Samarium Cobalt magnets have excellent resistance to corrosion and will largely remain unaffected by moisture and [...]
Advantages of Neodymium Magnet Epoxy Coating On the strong magnet coating is common is galvanized, nickel plating. Epoxy resin is believed to have many friends do not understand, some may not have seen or heard of this coating for the first time, today small make up to give you a detailed introduction, hope to help [...]
