Description:
Neodymium (NdFeB) magnets are powerful rare earth permanent magnetic 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 Automobiles, electric vehicle, Servo Motor, magnetic separator, Wind Turbine Generator, Medical Equipment, Elevators, Audio Equipment, 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: sintered Neodymium Iron Boron (NdFeB)
● Neodymium 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
If you need customized neodymium magnetic material products, please provide drawings and samples, or tell us the size, grade, quantity, plating, tolerance requirements, magnetic direction, etc. We will provide quotation and customized production according to your requirements.
