White Znic/Black Zinc plated
Zinc is a non-magnetic material, suitable for use inside the product. There is no strict salt spray test requirement, just as a decorative property, and it is generally used inside the product. The magnet is not exposed to the air.
3-5μm
No Standard Salt Spray Test
Colorful Zinc/Blue Zinc plated
Compared with white zinc, its anti-corrosion ability is obviously improved. It can pass the salt spray test for 24 hours when used in a relatively harsh environment.
6-12μm
24 hours
Nickel plated
The coating has a strong ability to withstand high-pressure accelerated aging tests. Suitable for the use of magnets exposed to room temperature and dry environment.
6-8μm
No Standard Salt Spray Test
Nickel-Copper- Nickel(NiCuNi)/Ni-Cu-Ni- Black Ni plated
Compared with single-layer nickel, it has better corrosion resistance, but the process is relatively complicated and the electroplating time will be longer.
10-16 μm
24-48 hours
Nickel- Copper-Nickel- Sliver plated
t has good decoration, the surface is not easy to change color, and the cost is high. It is used for products or occasions with strong decorative appearance. Salt spray resistance test is the same as NiCuNi
10-18μm
24-48 hours
Nickel- Copper-Nickel-Au plated
It has good decoration, the surface is not easy to change color, and the cost is high. It is used for products or occasions with strong decorative appearance. Salt spray resistance test is the same as NiCuNi
10-25 μm
24-48 hours
Chemical Nickel
Good corrosion resistance, the cost is high, suitable for products that are harsher to the environment.
10-30μm
96 hours
Epoxy plated
Generally the coating is black, the cost is high, with good corrosion resistance, suitable for humid environment
10-30μm
96 hours
