Product Description

Erose Sintered NdFeB Rare Earth Magnet
1, These Sintered NdFeB rare earth magnets are particularly suitable for high volumn production of a wide variety of shape and size ranges
2, Precise dimensional control is achieved in both processed and usually the component does not require futher machining.
3, Injection moulded NdFeB does not normally require coating due to high corrosion resistance, however coating is recommended for compression moulded NdFeB.
