Sintering SmCo magnets are circularly made by strict powder metal
technology and heat processing. This kind of magnet conveys
samariam for 35%, cobalt for 60%, element Fe and Cu. Through
altering proportioning of compositions and circulation of sintering
and heating, we can make two materials_ 1: 5 and 2: 17. The
difference lies in energy product, temperature coefficient and
coercivity. The most common material, 2: 17, has better property
and lower temperature coefficient, but it is more expensive and
should be magnetized in high magnetic field.
SmCo owns following advantages:
1. Possess strong magnetic properties - 5-7 times more powerful
2. Very steady in the conditions capable to cause corrosion.
3. Possess stable magnetic properties at high temperatures (to 350
4. Excellent corrosion resistance capability, no coating is needed
for surface protection
