Profile: S G Magnets Ltd. specializes in producing sintered & plastic bonded magnetic components and assemblies. We manufacture a range of silicon iron components for automotive and industrial solenoid applications. The material gives a combination of soft magnetic properties with the added benefit of high resistivity. Our sintered alnico magnets are manufactured by a powder metallurgy process which utilizes controlled atmosphere, high temperature sintering to produce near net shape parts. These may range in weight from as little as 0.05g up to 150g
