Product Description

Product Description

Neodymium magnet is also called" NdFeB magnet, or rare earth magnets", which is based on Nd2Fe14B. The main components are rare earth elements Neodymium (Nd), iron (Fe), and boron (B). Its main raw material is rare earth metal neodymium about 30%, metallic element iron about 65%, non-metallic element boron about 1% and other elements.

There are usually several common shapes for these strong  Neodymium magnets, such as disc magnet, block magnet, ring magnet and arc magnet. Almost all products are customized per dimensions or drawings from customer, usually an inquiry shall include these content: grade, dimension, tolerance, coating and magnetization direction. About magnetic property, there are usually N33 to N52, N35M to N48M, N33H to N46H, N33SH to N44SH, N30UH to N38UH, N30EH to N35EH etc. About coating, there are usually Ni-Cu-Ni(Nickel), Zn and Epoxy coating etc. These coating can protect magnets from rust. There are usually axially magnetized and diametrical magnetized. Our standard tolerance is ±0.05mm and ±0.10mm.
