Some customers have asked us whether neodymium strong magnet galvanizing can pass the salt spray test? Can you pass the 48-hour salt spray test? About this problem, Xiao Fu of Courage magnet, a permanent magnet manufacturer, will introduce it to you today.
Can neodymium magnet zinc plating pass the salt spray test for 48 hours?

Speaking of galvanizing, we should first understand the types of magnet galvanizing. At present, galvanizing is divided into many kinds, including white zinc, blue zinc, blue zinc, color zinc and black zinc. It can withstand 12 - 48 hours neutral salt spray test.
If the magnet needs 48 hours of salt spray, customers are generally recommended to use nickel plating. At present, the basic process of nickel plating is nickel-copper-nickel, and the appearance is brighter than zinc.
Guess your concern: Nd-Fe-B magnet galvanizing and nickel plating have an impact on magnetism? It doesn't matter. Magnet coating mainly from corrosion and rust, and then is the use of the hand is not easy to cut, will not affect the magnetic force.
