SM-03152030 Cylinder Neodymium Ndfeb Magnet High grade with NiCuNi Coated
Features
High Magnetic Performance: NdFeB magnets are the strongest commercially available permanent magnets, with energy products (BHmax) ranging from 35 to 55 MGOe (N35 to N55 grades). This high magnetic strength enables compact and efficient designs in various applications, including electric motors, wind turbines, and automotive systems. For instance, a cylindrical N48-grade NdFeB magnet with a diameter of 20mm and height of 10mm can generate a surface field exceeding 2,000 Gauss, making it suitable for high-torque motor applications.
NiCuNi Coating for Enhanced Corrosion Resistance: The NiCuNi coating consists of a triple-layer structure of nickel-copper-nickel, providing superior protection against corrosion compared to single-layer nickel coatings. This makes NiCuNi-coated magnets suitable for harsh environments, such as marine or automotive settings, where exposure to moisture and salt can cause rapid degradation. The coating also enhances the magnets' aesthetic appeal with a shiny, metallic finish.
Thermal Stability: High-grade NdFeB magnets, such as those in the N42SH or N48H series, retain their magnetic properties at elevated temperatures up to 120-150°C. This thermal stability makes them ideal for applications involving high temperatures, such as electric vehicle traction motors or industrial generators. The NiCuNi coating also aids in thermal management by dissipating heat generated during high-speed operation, preventing demagnetization.
Customization Options: Manufacturers offer tailored solutions for cylindrical NdFeB magnets, including varying diameters, heights, and magnetizations (axial or radial). The NiCuNi coating can also be customized based on specific application requirements, such as thickness or surface finish. This flexibility allows for precise integration into various mechanical and electronic systems.
Mechanical Versatility: The cylindrical shape facilitates secure mounting on shafts or rods, enabling precise alignment and rotation in applications such as robotics, conveyor systems, and magnetic bearings. The hole in the center also reduces weight without significantly compromising magnetic strength, optimizing efficiency in weight-sensitive applications like aerospace components.
