	NdFeB Rare Earth Magnet

	Permanent - Ferrite Magnet

	Plastic & Rubber Magnet

	Alnico

	SmCo

NdFeB, the third generation of rare-earth permanent magnet, has the high remanence, high coercive force, high-energy product and high performance/cost ratio, It is easily formed into various sizes and widely used in many fields such as aviation, electronics, instruments, meters, machine, medical instrument and the like. It is especially suitable for the development of high-performance, compact and light products.

The below - mentioned data of magnetic parameters and physical properties are given at room temperature. The maximum service temperature of magnet is changeable due to the ratio length and diameter and environmental factors.
