How to choose the specifications and types of coated magnets

When choosing a magnet, consider the standards and types of magnets from the following 4 aspects

1. Temperature

  Customers should choose their own magnet trademark according to their working temperature when choosing neodymium iron boron magnets. If the working temperature is higher than the magnet trademark acceptance temperature, the magnet will gradually demagnetize until it is non-magnetic. Please confess the working temperature and the trademark suitable for your own use before ordering.

2. Environment

If the magnet used is in a sealed condition, you can consider choosing a magnet with no plating or white zinc plating on the surface, which can save costs. If the magnet is exposed to humid air, especially under salt spray conditions, it is recommended to consider nickel plating on the surface. Magnet. Magnets should be stored in a monotonous, constant temperature environment, separated and wrapped with plastic, wood chips, cardboard, foam, etc. Keep away from ironware and objects that are easily magnetized, such as monitors, bank cards, computers, TVs, and mobile phones.

3. User goals

   Regarding environmental protection, users in relatively prosperous countries, such as North America, Europe, etc., should pay special attention to environmental protection issues. Export applications must pass the SGS EU six standards. Regarding users in China or some countries that are not prosperous, they don't think much about environmental protection. Flexible magnet

4. Transfer and stacking

  NdFeB strong magnetic material is hard, brittle, and has a strong magnetic field. It should be handled with care (except for large standards and thin sheets). When the strong magnet itself or other iron objects are attracted or separated, be careful not to operate. Otherwise, it is easy to damage the magnet or pinch your fingers due to knocks. Because NdFeB is classified as a multi-metal alloy material, the density is between 7.45, and it is heavy and brittle. Therefore, be extra careful when transferring to prevent magnetic shattering. During storage, the environment should also be monotonous, and not directly piled on the ground. It is recommended to use thick cardboard or place it on the shelf.
