Neodymium Block Magnet Engineering Data
How to Choose the Right Block Magnet Grade? (Strength vs. Temp)
A escolha da classe ideal consiste em encontrar o equilíbrio certo entre força magnética, custo e resistência ao calor.
- Neodymium Block Magnet Strength Grades: N55 offers highest force in a small size. N35 provides the best cost-performance for holding applications.
- Neodymium Block Magnet Heat Grades: Standard 'N' grades demagnetize above 80°C. For automotive, motor, or industrial sensors, you MUST use high-temp grades (e.g., M, H, SH, UH). Contact our engineers to validate your thermal requirements.
How to Choose the Right Block Magnet Coating
Iron in rectangular Neodymium magnets rusts easily, so a protective coating is essential. Here is a simple guide to help you choose block magnet plating.

What Are Neodymium Block Magnets?
Neodymium Block Magnets, also known as rectangular or cuboid magnets, are permanent magnets with a rectangular profile, including specific shapes like cube magnets and bar magnets. As a type of NdFeB magnet, they are sintered from an alloy of Neodymium, Iron, and Boron, making them the most powerful permanent magnets.
- High holding force over a large, flat contact area.
- Uniform magnetic fields for linear actuators and sensors.
- Easy integration into structural assemblies, channels, and fixtures.
Neodymium Block Magnets Applications
Neodymium block magnets excel in applications demanding high strength, structural stability, and deep magnetic field projection. They are the workhorses of industrial automation, used in heavy-duty lifting, separation, and clamping systems, and are fundamental to motion control in linear motors and large-scale generators. Their simple geometry also makes them ideal for creating powerful holding devices, mounting solutions, and complex scientific instruments like Halbach arrays, positioning them as a cornerstone of modern engineering and manufacturing.
