NdFeB Bonded Neodymium Magnet

Neodymium Bonded Magnets For Stepping Motor Carton Box Packaging

Product Description:

Bonded Neodymium Magnet is a high-performance magnet made from neodymium bonded with other metal alloys. It is a versatile and cost-effective solution for a variety of applications requiring high magnetic force. Bonded Neodymium Magnet is available in five grades: BN-4, BN-6, BN-8, BN-10, and BN-12L, all made with NdFeB alloy powder. It can be magnetized in three directions: axial, radial, or multi-poles, and can withstand temperatures up to 150°C. Bonded Neodymium Magnets are commonly used in various motors, including spinder motors, stepping motors, synchronous motors, DC motors, and brushless motors. As a reliable and cost-effective alternative to traditional rare-earth magnets, Bonded Neodymium Magnets are an ideal choice for applications requiring superior magnetic performance.

 

Features:

Advantages
