Product Overview
Sintered Neodymium Magnets are made of Neodymium-Iron-Boron (NdFeB) material, making them among the strongest permanent magnets available. Produced through a sintering process that compresses and heats the material in a mold, these magnets offer uniform structure and stable magnetic performance.
Key Features
High magnetic field strength and pull force
Nickel coating for corrosion resistance and smooth finish
Multi-polar magnetic orientation for precise field control
Customizable sizes and shapes to meet specific requirements
ISO9001 certified for quality assurance
