SSD is a hi-tech civil enterprise, specialized in fabricating, custom producing, trading and after sales services of magnetic materials, mainly produces Sintered Alnico magnets,Cast Alnico Magnets and FeCrCo Magnets, Alnico magnet powder and assembled magnetic materials, with annual output of ten hundred tons of Alnico magnets. The products are widely used in all kinds of meters and instruments, acoustics and audios, motors, sensors and other electronic fields. The alnico alloys we produce are up to the international advanced standard. Especially the high performance of permanent alnico magnet, with its high coercive force and stability, lower coefficient of Br and excellent temperature stability, can be used in aviation and space flight that need relay, short circuiter, contactor, etc. Some of our products have been applied into Shenzhou spacecraft 占쏙옙nd 占쏙옙 and Chinese new airplane. And some are used abundantly in hearing aids.
