Product Description

NdFeB ring magnets are mainly used in loudspeakers. The fast development in loudspeakers, earthphone or other audio equipment require very high energy neo magnet which has stable performance at high temperature. Our SH grade ring magnets are proved to be the one of best choices. As for high bonding power requirement for the magnets in assemblying to loudspeaker parts, surface tension of the coating is critical for magnet choice. Our trivalent chrome Zinc coating on neo magnets provide high surface tension and it is surely of environmental protection.
