FERRITE BLOCK MAGNETS
高性能バーマグネット
Ferrite block magnets are rectangular or square permanent magnets made from sintered ferrite materials. They usually have three main dimensions: length, width, and thickness. Their simple shape makes them easy to install, bond, or integrate into different magnetic circuits and mechanical structures. Compared with some rare earth permanent magnets, ferrite block magnets offer better cost-effectiveness and stable performance.
Custom Ferrite Block Magnets
As an experienced magnetic materials manufacturer, TOPMAG provides flexible OEM/ODM customization services to meet specific technical requirements.
Size Customization
Ferrite block magnets can be customized according to customer requirements, including length, width, thickness, and special dimensions. Custom sizes can meet different assembly structures and application requirements, from small sensors to large industrial equipment.
公差コントロール
We provide different levels of dimensional tolerance control according to application requirements.
Standard production tolerances can generally be controlled within ±0.1 mm. For high-precision applications, tolerances of up to ±0.03 mm can be achieved depending on the product size, structure, and machining requirements.
Magnetization Options
Ferrite block magnets can be supplied with different magnetization directions according to the magnetic circuit design and assembly requirements.
- Thickness Magnetization: This is the most common magnetization method for ferrite block magnets. The N and S poles are located on the two largest opposite surfaces of the magnet.
- Lengthwise Magnetization: The N and S poles are located on the two opposite end faces along the length direction of the magnet. This method is suitable for specific magnetic circuit designs and assembly structures.
- Widthwise Magnetization: The N and S poles are located on the two opposite surfaces along the width direction of the magnet. This method is suitable for specific magnetic circuit designs and assembly structures.
