XULONG Magnetics MANUFACTURY Co., Ltd
founded in 1984, is a high-tech enterprise, We specialized
in producing neodymium iron boron rare-earth permanent
magnets, sintered ndfeb, sintered ndfebs such as: N30-N48,
N30M-N45M, N27H-N42H,N27SH-N40SH, N25UH-N33UH, N25EH-N33EH.
With most advanced manufacturing equipment and facilities,
tremendous strength and sophisticated testing equipment,
We can manufacture magnet, sintered ndfeb, sintered ndfebs
with a variety of shapes, sizes and dimensions at the
requests of customers, have nickel, zinc, tin, epoxy and
aurum coatings applied to magnet. Some of them are highly
anti-corrosive. Now we awarded with the ISO9001: 2000
certificate of SGS United Kingdom ltd. Take the advantage
of our competitive price as well as supreme quality, reliable
services and prompt delivery, Our products, sintered ndfeb,
sintered ndfebs have entered into the international market
and meet the ovation of customers, Our annual output is
more than 450 tons.

| NdFeB magnet
is mainly made of Neodymium Iron and Boron,with excellent
magnetic property abundant raw material and reasonable prices,NdFeB
Magnet can be used as an ideal magnet in mini-motor Permanent
magnetic resonance sound device magnetic suspension system,magnetic
transmission machine and iatrical apparatus and etc.For NdFeB,its
surface is usually treatd with some special methods.The surface
treatment method include Zine Nickel Tin Silver Gold plating
Phosphor and Spray Epoxy Resin etc. |
