Product Description

 

Neodymium NdFeB Magnet

 Neodymium (NdFeB) magnets are rare earth magnet materials with high remanence, high coercivity and high energy. It can be easily made into various sizes and shapes, and is widely used in applications such as Electric Motors, Sensors, Meters, Audio Equipment, Magnetic Separators, Automobiles, Packaging, Toys, etc. It is easy to corrode in a humid environment, so surface treatment is usually required. Surface electroplating or coating treatment can be carried out according to customer requirements.
 

• Size: customized according to customer requirements
• Tolerance: usually ±0.1mm, it can also be made according to the tolerance required by the customer according to different sizes
• Material: NdFeB sintered Neodymium Iron Boron
• Grade: N35-N52; M series; H series; SH series; UH series; EH series; AH series
• Coating: Nickel-copper-nickel, Gold-plated, Zinc-plated, Silver-plated, Nickel-plated, Chrome-plated, Epoxy black-plated, Epoxy resin, PTFE, etc.
• Magnetic field direction: according to customer requirements
