What's the difference between galvanized and nickel plated magnets?

The most commonly used coatings for ammonium iron boron strong magnets are zinc plating and nickel plating. They have obvious differences in appearance, corrosion resistance, service life and price. The following are the key points.

Polishing difference: nickel plating is superior to zinc plating in polishing, and the appearance is brighter. Nickel plating is generally selected for products with high appearance requirements, while some magnets are not exposed, and zinc plating is generally used for products with relatively low appearance requirements.

Difference in corrosion resistance: zinc is an active metal and can react with acid, so it has poor corrosion resistance; After nickel plating surface treatment, its corrosion resistance is higher.

Service life difference: due to different corrosion resistance, the service life of zinc plating is lower than that of nickel plating, which is mainly reflected in that the surface coating is easy to fall off after a long service time, resulting in magnet oxidation, thus affecting the magnetic properties.

Hardness difference: nickel plating is higher than zinc plating. In the process of use, collision can be avoided to a great extent, resulting in angle loss and fragmentation of qintieboron strong magnet.

Price difference: in this regard, galvanizing has advantages. The price from low to high is galvanizing, nickel plating, epoxy resin, etc. After reading, do you know which coating you want to choose?
