8 12 Poles Magnetized Magnet
Product Description:
As formed, these magnets achieve high dimensional accuracy and
complex shaping.
These magnets are made by combining plastics with metal powder
having a combination (Nd-Fe-B) similar to that of sintered
neodymium magnets and then forming the mixture. Since the magnets
contain plastics, the magnetism is much lower. As formed, however,
these magnets offer the advantage of being processed into thin
products with high dimensional precision and products of complex
shaping. Moreover, isotropic magnets are easily magnetized radially
and can be magnetized in many varieties as well. Their temperature
characteristics are a little lower than those of neodymium magnets,
and are unsuited for use at 80°C or higher.
