4" diameter x 2" thick (101.6mm x 50.8mm)
There are more than 10 coating methods and coating is high temperature resistant, solvent resistant, and multi-colored. The common ways include Nickel-Copper-Nickel (Ni-Cu-Ni), Nickel (Ni), Tin (Sn), Zinc (Zn), Gold (Au), Expoxy, etc. Otherwise, magnets with high temperature resistance can be coated with rubber and silicon.
Although NdFeB magnet is a kind of hard and brittle material, we can customize some complex shapes according to customers requirements. We have produced some complex shapes such as different heads, convex, concave, slotted, side punched, cut corners, non-semi-circular and countersunk magnet.
The minimum thickness of ring magnet that AH Magnet makes is 1.5mm.The magnets has wide applicable temperature range from 80℃ to 230℃ and long service life.Highly stability under difficult environment conditions, high resistance to demagnetization, corrosion and oxidation.
Large neodymium magnets are composed of neodymium (Nd), iron (Fe) and boron (B) and are prone to rusting if exposed to these elements. To protect the magnets from corrosion and to strengthen brittle magnet materials, the magnets are often coated with nickel.
Neodymium (neo) magnets are part of the rare earth magnet family and are popular for their high strength in terms of compact size and weight as well as their high coercivity (they are permanently magnetized for use at temperatures below 590° F). the stronger the pulling power. Neodymium magnets are available in a variety of shapes, sizes and grades
