Strong Heat Resistant Custom Samarium Cobalt SmCo Rectangular
Magnet ISO9001
SmCo magnets have a wider operating temperature range, superior
temperature coefficients and greater corrosion resistance. Special
high temperature neodymium magnet superior to 150℃. SmCo magnets
not only perform well at high temperatures but also remain magnetic
even at temperatures below absolute zero (-273 ° C), making them
very popular for low temperature applications. Since most grades of
samarium cobalt contain almost no iron, they have excellent
corrosion resistance.
Properties of samarium cobalt permanent magnets
1. Samarium cobalt permanent magnet has high magnetic energy
product and high coercivity. Its magnetic property is better than
Alnickel-cobalt permanent magnet and ferrite permanent magnet.
2. Sm cobalt permanent magnet Curie has high temperature and small
temperature coefficient, which can be used at 300℃.
3. Samarium cobalt has high permanent magnet hardness, high
brittleness, low bending strength, tensile strength and compressive
strength, and is not suitable for use as structural components.
4. The main component of samarium cobalt permanent magnet is cobalt
metal (CO ≥99.95%), so it is expensive.
Because of the properties of samarium cobalt permanent magnet, we
hardly see any samarium cobalt permanent magnet in everyday
products.
If an aesthetically pleasing or corrosion-resistant coating is
desired, nickel, zinc, gold, or epoxy or other coating may be used.

Note | For large bread products, no thin size is allowed, because SmCo's
huge brittleness will easily cause breakage during assembly |
