product name super Strong Neodymium Permanent magnet
To quote, we need the following information:
1) General magnetic properties
2) Nominal dimension
3) Direction of orientation
4) State of Orientation(need to be magnetized or not)
5) Quantity
6) Magnet size
1) Constitution: 35% Sm, 60% Co and 5% Fe & Cu
2)SmCo Magnet(Samarium Cobalt magnet) has superior resistance to high temperature(max temp reaches 350 degree centigrade).When working at above 180 degree centigrade, its maximum energy product BH and temperature stability are superior than NdFeB magnet.
2)Excellent resistance to corrosion, no coating is needed for the surface protecting.
3)SmCo is suitable for machines with high magnetic requirements and good for strict working environment requirements
General Description:
1. Two common compositions of SmCo magnets are SmCo5 and Sm2Co17.
2. Generally, the cost of Sm-Co magnets is higher than Nd-Fe-B magnets.
3. As a big advantage, Sm-Co magnets can operate at higher temperatures up to 300 degrees Centigrade.
4. Sm-Co magnets are widely used in applications in which higher operating temperature and higher corrosion and oxidation resistance are crucial.
5. We are high-tech enterprise based on the perfect combination of capital and technology, the main products cover Smco5 and Sm2Co17 magnets, samarium cobalt powder and various assemblies etc.
Comparison of NdFeB and SmCo Magnet
| Material | Energy Products | Mechanical Strength | Density(lbs/in3-gm/cm3) | Corrosion Resistance | Temperature Stability | Cost |
| NdFeB | 10 to 48 | Medium | 0.275-7.5 | Low | Low to Medium | Lower |
| SmCo | 15-32 | Low | 0.300-8.3 | High | High | Higher |
Features of samarium cobalt magnet:
1, High(BH)max, high Br and high Hc with high operating temperature, low temperature coeficient, counter-demagnetization, decay resistance,
2, which applied in the high tech fields of communication, automobiles, computers, medical treatment, electric machinery, military project and aerospace.
