How to judge the quality of NdFeb magnet?

First of all, you can start from the appearance, the surface should be smooth and smooth, no cracks, bubbles, these defects. The coating must also be uniform and dense with strong adhesion. The dimensional accuracy can not be sloppy.

Performance testing is also critical. Look at the magnetic parameters, such as remanence, coercivity, maximum magnetic energy product, etc., the higher the value is usually the better the performance. Also pay attention to temperature stability, magnetic properties can not change too much at different temperatures. Corrosion resistance can not be ignored, otherwise it is easy to rust and corrosion.

In addition, the manufacturer is also very important, to choose a qualified and reputable manufacturer, Tecomag is a good choice oh!

When choosing Ndfeb magnets, we must pay more attention to these aspects, so that we can choose a good quality magnet.
