3.Magnet Coating:

Ndfeb magnets plating include: nickel, copper, chromium, gold, black zinc, epoxy resin.different coating has different colours,also the hold time is different also. each has their advantages and disadvantages.

1) zinc: the surface looks is silvery white, can do 12-48 hours salt fog, can be used in some glue adhesive, such as AB glue.If electroplating good can be stored for 2-5 years, its advantage is low price.

2) nickel: looks like stainless steel color, if stay in the air, surface are difficult to oxidation, and good-looking appearance, good gloss, electroplating could pass 12-72 hours salt spray test.Its disadvantagecannot be used with glue adhesive,it will make the coating fall off,Accelerate the oxidation.now in the market , NiCuNi coating could be electroplating for 120-200 hours salt spray, but the plating cost is relatively higher.

3) copper: in hardware industry, ndfeb industry rarely used, its appearance is yellow.

4) Cr: chromium electroplating industry is rare, cost is very high, generally could not accepted by the c
