Our Permanent Neodymium Ring Magnets are mainly used in loudspeakers. With the fast development in the applications of loudspeakers, earthphone or other audio equipment, it requires very high energy Permanent Neodymium Ring Magnet which has stable performance at high temperature. Our Permanent Neodymium Ring Magnets in high grade like N38SH are proved to be the one of best choices.

As the corrosion resistance of the Permanent Neodymium Magnets is considered poor,the surface coating or plating is normally required for the Permanent Neodymium Magnets, Our trivalent chrome Zinc coating on Permanent Neodymium Magnets provide high surface tension and it is surely of environmental protection.
