Sintered NdFeB Magnets
Product Description：
1.Max working temperature is only for reference which epends on the circuit what the magnet is applied for. 2.When L/D ratio of testing piece is eaqual to 0.7,the open flux irreversible loss at Max.Working Temperature less/eaqual 5% is guaranteed.(Lmeans magnetization direction length,D means diameter of magnetic pole surface.) 3.We suggest users to consult us on any application when the magnet’s temperature is near to 150℃.
