Properties of samarium cobalt permanent magnets
1. Samarium cobalt permanent magnets have excellent corrosion and
oxidation resistance, so they do not require any coating:
2, samarium cobalt permanent magnet has high magnetic energy
product and high coercivity, its magnetic energy product can be as
high as 239kJ /m3(30MGOE), magnetic performance is better than
aluminum-nickel-cobalt permanent magnet and ferrite permanent
magnet, is ferrite permanent magnet 8 times, aluminum-nickel-cobalt
permanent magnet 3 times. Therefore, the permanent magnet component
made of SMCO permanent magnet system has light weight, small volume
and stable performance, which can be used in electroacoustic
telecommunications equipment.
3. Samarium cobalt permanent magnet with high Curie temperature and
small temperature coefficient can be used at a high temperature of
300 degrees.
4. Samarium cobalt permanent magnet has high brittleness, high
hardness, low bending strength, tensile strength and compressive
strength, so it is not suitable to be used as structural parts.
5. The main component of samarium cobalt permanent magnet is cobalt
metal (Co99.95%), so it is expensive.
1:5 SmCo Magnet
SmCo1:5 Magnet is also called SmCo5, the highest working can be
250℃.Based on Sm,Co and some other metals. After processing of
melting, milling, compression moulding and sintering. To make work
blank with different levels of performance.
