Magnet Materials

China Magnets Source Material Limited specializes in supply magnet materials: neodymium magnet, samarium cobalt magnet, AlNiCo magnet and ceramic (ferrite) magnet.

They are objects made from a material that is magnetized and creates its own persistent magnetic field and don’t require a continuous supply of electrical energy to maintain its magnetic field. So they are also called permanent magnets in contrast to electromagnets.

Meanwhile, NdFeB magnet and smco magnets also are rare earth magnets because of using alloys of rare earth elements. Rare earth magnets are strong, but expensive permanent magnets that use on many applications. Their greater strength allows smaller and lighter magnets to be used. Thus, the volume of end products is also smaller and smaller.

The Comparison of Different Magnet Material:

1. Neodymium Magnets, the Last development in the high energy magnets (33-56 MGOe) but not the final, very poor corrosion resistance (coating: NiCuNi, Epoxy, ABS, Parylene); there are range of operating temperatures 60°C to 220°C) which can sufficient for most application. If you need higher working temperature, smco magnet is a good choice.

2. Samarium Cobalt Magnets, higher energy product values (9.5-32 MGOe) and greater temperature stability (250-350℃) and excellent resistant to oxidation. Smco magnet is a good replacement of neodymium magnet when higher working temperature is required.

3. Alnico Magnets: high maximum operating temperature 550℃, very good corrosion resistance, but low Energy Product (BHmax) about 1-11.5MGOe. They can be made into different complex shapes; horseshoe and cylinder are classical alnico shapes.

4. Ceramic Magnets, excellent in peak magnetic product and greater resistance to demagnetization, good resistance to corrosion and cheap in price. Only when making some shapes and sizes, mold fee is necessary. They are good balance of magnetic strength, resistance to demagnetizing and economy.
