Our industrial strength magnets are used to adjust a variety of functions. We have all the sizes, styles and materials’s that you will need for your various applications. If there isn’t a stock size that meets your requirements, we can custom make industrial strength magnets for you.
A magnet grade is a measure of the strength of a magnet and in most cases a higher number indicates a stronger magnet. The grade number starts with the letter N for neodymium magnets. The number that follows is the maximum energy product of the magnet in Mega-Gauss Oersteds. This is the primary indicator of a magnets strength. The greater the number, the greater the magnetic field the magnet will generate in an application and represents the strongest point on the BH Curve (Magnet’s Demagnetization Curve).

Our factory focused on development and manufacturing of Neodymium magnet, has more than 10 years manufacturing experience in producing various sizes, different shape and surface coating.Over 45 different grades of neodymium magnet (strong magnet), they are widely used in automotive industry, clean energy, consumer electronics, sound device, home & office use, health care, separation filtration equipment, and other industry. Epoxy Plated Neodymium Iron Boron Sector Magnet, N55 Sintered Neodymium Segment Wedge Magnet For Electric Motor
Strong Neodymium Magnet has poor resistance to corrosion, in order to prevent neodymium magnet from corrosion, surface coating is needed. There is a variety of surface plating available, such as, Nickle plating, Nickel-Copper-Nickle plating, Epoxy resin plating, Zinc plating, gold coating, rubber coating and more. N50 Sintered Neodymium Aline Magnets , Nickel coating and Nickle-Copper-Nickle coating are the most common plating for most applications.
