Detailed Introduction of Nd-Fe-B Square Magnet

Size introduction of Nd-Fe-B square magnet:
When purchasing Nd-Fe-B square magnet, the manufacturer should give specific size and performance data, so that the manufacturer can customize it accurately. The size of Nd-Fe-B square magnet is length (l)*width (w)*height (H). Usually, the manufacturer uses F as the beginning to represent the square magnet. For example: F10 *6 *4mm, which means that its length is 10mm, width is 6mm, thickness (height) is 4mm, generally the default last number is the magnetization direction of the magnet. For example, the NdFeB square magnet of F8 *4 *2mm is magnetized in the direction of 2, that is, in the direction of thickness (height). The N S pole is on two large surfaces, i.e. 8 *4mm, one side is N pole and the other side is S pole.

Introduction of magnetism of Nd-Fe-B square magnet:

At present, N35 performance is a widely used and cost-effective material in the market. If the size of the material can not be changed, it needs to improve the performance of the material to meet the requirements of the product. GME magnet also has a very strong advantage in the high-performance material: "high magnetic performance, magnetic stability, resolute." Do not use low-performance materials instead of high-performance materials to deceive customers.

Introduction of Nd-Fe-B square magnet surface coating:
If the surface requirements are not high, zinc plating is usually used, because the price of zinc plating is cheaper than that of nickel plating. If the magnet is used in a humid environment or with salt spray requirements, then nickel, copper and nickel plating, epoxy plating and so on should be adopted. The maximum salt spray resistance test of epoxy plating is 96 hours.
