Product Description:
Bonded Neodymium Magnet is a kind of permanent magnet made of neodymium iron boron material. It has the advantages of high performance, high magnetic energy product, high coercive force, low temperature coefficient, excellent corrosion resistance, strong shock resistance and low cost. It has been widely used in many applications, such as spinder motor, stepping motor, synchronous motor, DC motor, brushless motor, etc.
Bonded neodymium magnet is a kind of permanent magnet with bonded arched NdFeB magnet. It can be customized into different shapes, such as disc, block, cylinder, ring, etc. The surface of magnet can be coated with epoxy, nickel, parylene, etc. to protect the magnet from corrosion or other environment factors. The minimum order quantity (MOQ) is 100 pieces.
Bonded neodymium magnet is a high-performance and cost-effective product for many applications. It has strong magnetic field with high coercive force, which can be used in many industrial applications. It is also an excellent choice for small-scale projects due to its low MOQ requirement.
