1. Square size refers to length (L) × width (W) × height (H), generally using F to indicate the square. For example: F30×20×3mm, which means that the rectangular magnet is 30 mm long, 20 mm wide, and the thickness (height) is 3 mm. The default last digit is the magnetization direction of the magnet, F30×20×3mm. The square magnet has a magnetization direction of 2, that is, a thickness (height) direction. The N S pole is on the two largest faces, that is, the 30 × 20 mm face, one side is the N pole, and the other side is the S pole.

2. Magnet working environment:

When selecting a magnet, select the appropriate NdFeB grade according to its working environment. If the working temperature is higher than the temperature of the brand for a long time, the magnet will gradually demagnetize until it is non-magnetic. Please confirm the working temperature and the suitable use before ordering. Material.

3. Magnetic and surface coating:

At present, the performance of N35 is widely used and cost-effective. If the magnetic force needs to be increased if the size cannot be changed, the material performance can be improved to meet the product requirements. The magnetic magnetic industry is also very advantageous in high-performance materials. High energy, stable magnetic, and no need to replace low-performance materials for high-performance materials. Surface coating: If the surface is not high, galvanizing is generally used to protect the magnet. If the magnet is used in a humid environment or has salt spray requirements. It can be nickel-plated copper-nickel, epoxy-plated, etc. The epoxy-coated epoxy can be tested for up to 96 hours.
