N42 Permanent rare earth neodymium magnet ring diameter 20mm

neodymium magnet ring diameter 20mm

Neodymium magnet ring product feature:

1, High performance, demonstrating high remanence and coercivity, for high Br decide neodymium magnetic have high strength.

2, High operating temperature, adjust the material of Dysprosium and Terbium on the magnet, the operating temperatures up to 240°C

3, neodymium magnet made of iron, it depends magnets easy to process into the size of your need, shade magnets, ring, disc, rod, rectangle, a magnet with holes.

4, Compare to other magnets, the price of neodymium magnet more competitive.

Plated on Neodymium magnet :

Neodymium magnet made up of Neodymium, Iron and Boron.the material of iron decides if don’t plate, magnet easy get rust. Normally we will suggest customer choose the plated as follow:

1.Zinc: Its anti-corrosion ability is a little weaker. So it can be used in short term anti-corrosion environment. Its advantage is beautiful in appearance because of its color, its permeability is better than Ni-Cu-Ni.

2.Ni-Cu-Ni: It is the standard coating Unless requested otherwise, this NicuNi coating is always applied to the magnets.

3. Gold: Gold always used in electric and jewelry

4.Epoxy: Excellent viscose ability, good conductivity, high hardness, good flexible

If need other plated, please contact us.thanks.
