This type of magnet achieves the highest magnetic energy of all permanent magnets now in practical use. The main phase of the magnetism of rare-earth magnets developed conventionally was a two-component alloy. However, neodymium magnets combine neodymium with iron and boron to constitute a three-component, anisotropic-sintered rare-earth magnet with an atomic ratio of Nd 2 Fe 14 B 1.
The neodymium magnet exhibits excellent performance in terms of size reduction, thinning, weight reduction and enhancing the efficiency of applied equipment. However, its magnetic characteristics and corrosion-resistance performance require caution in use of the product at high temperature. For the dynamic characteristics of the product at high temperature, the Br temperature characteristics of the magnet must be sufficiently considered.

– The main characteristics of neodymium magnets are as follows:
a) Its maximum energy product (BH max) far exceeds that of ferrite (4.5 MGOe) and samarium-cobalt magnets (30 MGOe). Some models even exceed 48 MGOe.
b) Since it consists mainly of relatively inexpensive neodymium and iron, it offers better cost performance than samarium-cobalt magnets that contain much cobalt, and poses no concern over availability.
c) Although these magnets have temperature characteristics inferior to those of samarium-cobalt magnets, heat-resistant materials have been developed with higher magnetic coercive force for the following: NF-H series, NF-SH series and NF-UH series.
d) Of the main components, iron accounts for nearly 70%. To ensure rustproofing, these magnets are equipped with Ni electrolytic plating as standard.

Huge Block N45M Magnets For high-temperature demagnetization, refer to the Hcj temperature characteristics of the magnets. For the NF series, we therefore provide different materials with various Hcj levels. Even with the same material, these magnets vary in demagnetization characteristics according to shape. These materials also make the magnets prone to rusting.
Therefore, the products should undergo surface treatment
