Big Ring Magnets of Neodymium

Specifications

Neodymium 

A neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron, with great performance and competitive price. 

Shape 

We can produce magnets of various shapes. 

Commonly used shapes include Disc, Cylinder, Block, Ring, Countersunk, Segment, Trapezoid, Irregular shapes and more. 

Customized Design (Design proper magnets for clients specific requirements)  

Main Grade for Neodymium

N33, N35, N38, N40, N42, N48, N50, N52 (M, H, SH, EH, UH,AH)

Coating 

Coating is an in alienable component of NdFeb magnets. It prevents these magnets from oxidation. 

Widely used coatings are Ni-Cu-Ni, Nickel, Zn, Gold, Silver, Copper, Epoxy, Chemical, PTFE, Parylene, Everlube, and Passivation.

 Properties Of Various Neodymium Magnets

- Remanence (Br), which measures the strength of the magnetic field;

- Coercivity (Hci), the material's resistance to becoming demagnetized;

- Energy product (BHmax), the density of magnetic energy
