What is the difference between a cedar cobalt magnet and a neodymium iron boron magnet?

Cobalt magnets (SmCo magnets) and neodymium iron boron magnets (NdFeB magnets) are two rare earth permanent magnet materials with commercial applications and excellent performance. They are different in performance, price, etc.

Composition - The fir cobalt magnet is mainly composed of neodymium (Nd) and cobalt (Co).

Neymium iron boron magnets are mainly composed of neodymium (Nd), iron (Fe) and boron (B).

Magnetic properties:

1. The neodymium iron boron magnet has extremely high coercive force and residual magnetic induction strength at room temperature, which is one of the most widely used permanent magnet materials at present.

The magnetic performance of the fir cobalt magnet is relatively low, but it still has high coercive force and residual magnetic induction strength.

Thermal stability:

2. Cedar cobalt magnets have good thermal stability and can work at higher temperatures in some high temperature environments.

The thermal stability of neodymium iron boron magnets is poor, and the magnetic performance is easy to decline at high temperatures.

Manufacturing difficulty and cost: - The manufacturing process of neodymium iron boron magnets is relatively mature and easy to produce, so it is low.

3. The difficult shan cobalt magnet has high magnetic properties and is widely used in the field of electronic products; while the shan cobalt magnet has good thermal stability and is suitable for high-temperature environments. The material should be selected according to the specific application scenario and decision.
