China Neodymium And Ferrite Magnets Manufacturer & Supplier 
The nickel-plated ferrite circular magnet is a magnetic component that uses sintered ferrite circular magnets as the base material and adds a metal coating on its surface. Compared to conventional "bare black ferrite," this product exhibits significant differences in appearance, corrosion resistance, and certain application scenarios.
The following picture is not necessarily a neodymium circular magnet, but actually a coated ferrite magnet. Nickel plating on ferrite can enhance the appearance and texture, but the cost will increase.

Nickel-plated ferrite magnets are generally not used inside products; instead, they are more commonly used in the exterior components of consumer products as a low-cost alternative to some neodymium-iron-boron exterior components.
As for your options, ferrite magnets do not require plating unless absolutely necessary; they can be used as-is. However, if you do require plated ferrite magnets, please contact our customer service team for a quote.
