Determine Strong Magnet Quality

NdFeB magnets are popular word products in the market. At present, the demand in China’s market is getting bigger and bigger, and the bidding is getting bigger and bigger. Many magnet manufacturers have better competitive advantages in the market. Will reduce the cost by using inferior raw materials. Therefore, when buying a powerful magnet, you must know how to distinguish the quality of the powerful magnet, so that we can buy a better quality powerful magnet.

Strong Magnet Quality

Strong Magnet Quality

Identification method:

Judging the quality of a powerful magnet is mainly analyzed from two angles: magnet performance, magnet appearance

Strong magnet performance:

The standard for the performance of strong magnets is that there is no uniform standard. When distinguishing, it is only necessary to investigate the relevant parameters of the powerful magnet, such as magnetic energy product, coercive force and residual magnetism. It is impossible to distinguish the magnetic energy product of a powerful magnet with a Gauss meter or a flux meter in a powerful magnet of different specifications. Only the static magnetic characteristic tester can be used at this time.

NdFeB magnet appearance:

The inspection of the appearance of strong magnets mainly includes five categories:

1. There are scratches on the magnet (including scratches, line marks, knife marks, etc.)
2. There are pitting on the magnet (including pitting, pockmarks, bubbles, scars, slag layer, partial over-thickness, electroplating)
3. There are cracks on the magnet (including cracks, cracks, etc.)
4. There are edges on the magnet (including edge, chipping, material residue)
5. Blisters (including sand holes, pores, pinholes, particles, etc.) to see if there is a missing corner, whether the plating is intact, whether the size meets the design requirements; NdFeB generally has a plating layer to protect it from corrosion, Rusty. In general, magnets of the same specification are placed on a flat surface that can be adsorbed to distinguish the magnitude of the magnetic force.
