High remanence neodymium block magnet at best price in China

block magnets are super strong magnets for multi-purpose. This set contains bar shape magnets with hole which are well coated, they are triple layer coated for good rust resistance.It looks shining on surface and could last long. These are permanent magnet and will not lose their magnetism even when close to other magnets or drop down.

Warning:1.Don't swallow, This product contains small magnet, Swallowed magnets can stick together across intestines causing serious or fatal injury, Seek immedicate medical attention if magnets are swallowd or inhaled

2. Don't put them in nose or mouth which are so super strong, And must be kept far away from Children

Production process chart of NdfeB:

1 The reversible temperature coefficient depends on the aspect ratio of the product, square graph (demagnetization curve), etc. Please note.

2 Under the premise of special process level, low weight loss products are corresponding to low temperature coefficient data.

3 For the magnetic generators such as wind turbine generators, tidal generators, biogas generators, and elevator hoists that require high reliability, we recommend the use of low-weight-loss LT series products. At the same time, the body's corrosion resistance can be improved and its life extended. Reduce equipment maintenance costs.

Production process

High-remanence-neodymium-block-magnet-at-best-price-in-China.png

1. Raw materials are prepared according to Nd2Fe14.

2. Put the prepared raw materials into the vacuum melting furnace (or flaking furnace) and conduct high temperature smelting to form alloy ingot (or flaking plate).

3. Alloy ingot (or slabs) is ground into magnetic powder particles only a few microns in size by air flow.

4. Press magnetic powder in magnetic field according to actual requirement.

5. After molding of billet in high temperature above 1000 vacuum sintering, and then to aging treatment in order to achieve the corresponding magnetic.

6. Magnetic performance testing.

7. Perform mechanical processing and surface treatment according to the size and shape required.

8. Visual inspection.
