Surface Coating

Coating Layer	Typical Application Environment	图片
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 coating with relatively low resistance to corrosion)	Providing good corrosion protection against atmospheric 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 + Tin(multiple coating)	Suitable for soldering or electric contact on the surface
Epoxy coating	Providing good corrosion protection against atmospheric influences, humidity as well as chemicals.
Passivation	Protecting uncoated magnets temporarily, e.g. During transport or short term storage.
