    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 disadvantage : cannot 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 company.but it is very difficult to react with other substances.Mainly use where the PH is stronger, the domestic product prices are low, so people rarely use.

    5) Gold: now the industry is very popular, we saw some stalls gold-plated bracelet mostly yellow gold or copper.Gold-plated products appearance looks just like gold is very beautiful, more commonly used in hand act the role of industry, our products can be gold-plated, used for magnetic bracelet.

    6) epoxy resin: the product is  nickel plating+ a layer of resin paint,  its development is very fast these years, a lot of people are now used in all kinds of plating products, its biggest advantage is that can do the color you want.
