Presently, sintered neodymium magnets possess the strongest magnetism in permanent magnets, the grades range is from N35 to N52.
Neodymium permanent magnet is a kind of hard and brittle material and susceptible to be oxidized and corroded. Currently the most effective way to prevent sintered neodymium magnets from oxidizing and corroding is surface treatment, like nickel, zinc, gold, black epoxy etc, among which nickel coating the most commonly used material.

Nickel-coated neodymium magnets look silver color, with a smooth surface and strong antioxidant properties. What shown in the above picture are nickel-coated magnets produced by our company.

Adopts advanced production technology, our company are specialized in producing various shapes and sizes of nickel-coated neodymium magnets according to customer requirements. These shapes include disks, magnetic ring, magnetic bar, pentagon, ball, convex as well as slotted permanent magnet products.
Besides, we can produce a variety of magnetic devices, such as magnetic lifter, magnetic plate, magnetic filters, magnetic tool holder, magnetic albums, magnetic hook, magnetic toys, etc.

Generally different shapes and sizes have different applications. For example, the pentagon, the wafer and the beads are often used to magnetic jewelry and magnetic health products; the pyramid shape and diamonds can be used in interior decoration and magnetic toys; Magnets with big sizes like the cylindrical magnet and cubic magnet in the picture are generally applied to industrial field.

Big nickel-coated magnets need to be separated from each other by gaskets. But due to their strong antioxidant capacity, vacuum-packing is not needed.
