Sintered NdFeB
The fast development in loudspeakers, earthphone or other audio equipment require very high energy neo magnet which has stable performance at high temperature. Our 38SH ring magnets are proved to be the one of best choices. Our 38SH material is used widely by JBL Professional in US.
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.
