In order to increase the corrosion resistance and to meet the designated surface demands of the magnets,Shenghua Magnet can provide customers with magnets of following coating layers.

Zinc(Zn coating with relatively low resistance to corrosion):
Providing limited corrosion protection such as humidity-proof ,weak corrosion or temporarily stain-proof.

Zinc(Zn coation with relatively high resistance to corrosion):
Providing good corrosion protection against atmodpheric influences,humidity as well as chemicals.

Nickel(multiple coating copper +nickel):
Safely exposed to environment possibly with dew,and remaining stability for a long lifetime both in appearance and performance.

Nickel+Sn(multiple coating):
Suitable for occasions repuiring soldering or electric contact on the surface.

Epoxy-coating:
Providing good corrosion protection against atmospheric influences,humidity as well as chemicals .

Phosphated-coating:
Protecting uncoated magnets temporarily,e.g. During transport or short term storage.
