Features
High Magnetic Performance: Neodymium 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 example, a small fan-shaped N42-grade neodymium 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.
Zinc Coating for Corrosion Resistance: The zinc coating provides a protective layer that shields the magnets from corrosion caused by moisture, oxidation, and chemical exposure. While zinc coatings are less durable than nickel coatings in harsh environments, they offer adequate protection in mild conditions and are more cost-effective. The zinc layer also provides a smooth, matte finish that enhances the magnets' aesthetic appeal.
Cost-Effectiveness: Zinc coatings are a cost-effective solution for protecting neodymium magnets, especially in applications where high corrosion resistance is not critical. The lower cost of zinc compared to other metals like nickel makes these magnets an attractive option for budget-conscious projects.
Thermal Stability: Although zinc coatings have a lower melting point than nickel coatings, small fan-shaped neodymium magnets with zinc coatings can still operate effectively at temperatures up to 80°C. This makes them suitable for use in motors, generators, and other devices that generate moderate heat during operation.
Customization Options: Manufacturers offer tailored solutions for small fan-shaped neodymium magnets, including varying diameters, heights, and magnetizations (axial or radial). The fan shape can also be customized to meet specific application requirements, such as the number of poles or the angle of the fan blades.
Environmental Friendliness: Zinc is a more environmentally friendly coating material compared to some other metals. It is non-toxic and can be easily recycled, reducing the environmental impact of magnet production and disposal.
Product Details
Introduction
Small fan-shaped neodymium magnets with zinc (Zn) coatings are specialized permanent magnets that combine the exceptional magnetic properties of neodymium-iron-boron (NdFeB) alloys with the corrosion-resistant benefits of zinc plating. These magnets are designed in a fan shape, which allows for precise magnetic field control and mechanical alignment in applications where space is limited or a specific magnetic orientation is required. The zinc coating provides a cost-effective solution for protecting the magnets from environmental factors such as humidity, oxidation, and mild chemical corrosion, extending their operational lifespan.
