  • Micro Magnets

We supply micro magnets in Alnico, NdFeB, SmCo, Ceramic FeCrCo with very tight tolerances as well as NdFeB micro magnets with high quality parylene cating, Ni, Ni black and gold-plated. These magnets are used many applications include industries as diverse as medical applications, medical devices, micro motors, and sensors.

We can provide magnets in Neodymium Iron Boron, SmCo, Alnico, or any other magnetic material, and offer coatings and platings that are biocompatible, including Parylene and Titanium cases.

One of our most technologically sophisticated magnets is a Micro Magnet designed for a medical application. This magnet is offered in Neodymium Iron Boron with energy products up to 52 MGOe, and coated with an inert biocompatible protective coating.

In addition to medical applications, uses include micro sensors for use with Hall Effect Chips, and reed switches, wrist watch movements, and micro motor designs.

The diameter can be supplied as small as 0.010” [0.25 mm], with tolerances after coating or plating as tight as ±0.0003” [±0.008 mm], depending upon material.

We offer a wide variety of micro magnet products and services. We are good at micro magnet, normly very small and precise magnets. We can supply Alnico, NdFeB, SmCo, ferrite and other materials with very good tolerances. The size(diameter or length) could be at 0.1-10mm, and the tolerance could be +/-0.005~+/-0.02mm with various shapes.

high-temp resistant ring magnet for mobile phone, vibration motor. It is applicable for mobile phone, vibration motor featuring high-temp resistance, with high-temp resistant and corosion resistant Sm2Co17 as raw material, can be tooled according to customers’s drawings, have been applied to many famous brands of mobile phones based on a batch quantity. We are specialized in precision machining of magnets. in micro-appliances including deep-hole thin wall ring magnet elements, enjoying a high competitiveness within market both at home and abroad. The specific shape and size can be available by producing according to different drawing designs from customers.

The various magnet can be widely used to make into super hard micro magnetic precision parts for timekeeper, micro-motor, optical communication electronics, electroacoustics, digital camera etc. SmCo magnet is a kind of permanent magnet mainly made of Rare Earth  samarium, metal Cobalt and other elements. It features high energy product, very low temperature coefficient, and a relatively stable magnetic property under high temperature. Besides, with strong anti-corrosion resistance, generally it doesn’t need any electroplating at all, it can widely applied in motor, meter, sensor, radar, magnetic drive and other high-tech areas. Holding Systems Grip Fast Magnets
