Neodymium Iron Boron disc magnets

A neodymium magnet (also known as NdFeB, Neodymium Iron Boron magnets Neo magnet), is a type of rare-earth permanent magnet. It is made from an alloy of neodymium, iron, and boron to form the Nd₂Fe₁₄B tetragonal crystalline structure. This material is currently the strongest type of permanent magnet in the world.

Pic shows the Neodymium Iron Boron disc magnets with Zinc coating,the magnetized direction is through the diameter.

Nd-Fe-B permanent magnet is manufactured in a wide range of shapes, sizes and grades according customer's demand.

NdFeB has a very high energy product and coercivity, can pick up 660 times of own weight of heavy objects.

The advantage is high cost-effective, with good mechanical properties, easy cutting; according customer's demand to manufacture in a wide range of shapes, sizes and grades.

Mostly of rare earth permanent magnet always work do not at room temperature or under vacuum, in order to keep the accuracy of shape size and avoid the Corrosion and oxidation, we must make the coating on the surface,such as zinc, nickel, silver, gold, etc., can also be done phosphorus treatment or spray epoxy resin to slow down the oxidation rate.

Sometime, the customers have high demand of NdFeB anti-corrosion, antioxidant, we can design the magnet,add some elements, such as: niobium, vanadium, cobalt and other metal to replace part of the iron to catch the customer requirements of the acid and alkali resistant,antioxidant level, however, because of special material, we need MOQ for it.

The main physical properties of Neodymium Iron Boron disc magnets

The magnetic properties of compare NdFeB and SmCo

The application of Neodymium Iron Boron disc magnets, we are easy to only pay attention to the magnetic properties of materials, the stability of its great importance is not enough, the stability of the material used, including stability, temperature stability, external magnetic field under the action of stability, and ironmagnetic material exposure to the role of stability, stability under mechanical action, the stability of the-ray irradiation, chemical stability and so on.

So when you choose the magnet, pls consider more.
