NdFeB and SmCo performance comparison

Hits:Updated:2016-05-12 14:05:08【Print】

How different operating temperature, select the appropriate magnet, reduce costs, improve product quality, has been plagued by many designers of a problem, not high temperature magnet selection, use will be problems, affect product quality; selection of high temperature magnet, there is no waste of magnet properties, to the product add unnecessary costs?
 
Let's do a simple comparison on NdFeB and SmCo performance under high temperature conditions.
At 150 degrees Celsius, is the strongest performance NdFeB magnet, its magnetic far stronger than the other rare earth permanent magnets.
At 150 degrees Celsius, the magnetic neodymium magnet weaker than samarium cobalt.
NdFeB maximum operating temperature is 230 degrees, and samarium cobalt can be stable job at 300-350 degrees Celsius environment.
