What Are N35UH Magnets?

N35UH magnets are a type of high-performance permanent magnet within the neodymium-iron-boron (NdFeB) family. The "N35" indicates that the magnet has a maximum energy product of 35 MGOe, representing the product of magnetic field strength and magnetic flux density—an important measure of magnetic force. The "UH" designation stands for Ultra High Temperature, meaning the magnet is engineered to operate in high-temperature environments, typically up to 150°C (302°F).

Key Features of N35UH Magnets

High Energy Product

N35UH magnets possess a relatively high energy product, enabling them to generate strong magnetic fields. This makes them suitable for applications requiring powerful magnetic performance.

Excellent High-Temperature Stability

Compared to standard NdFeB magnets, N35UH magnets offer superior thermal stability. They maintain strong magnetic performance at elevated temperatures and are less prone to demagnetization. This makes them ideal for use in demanding environments such as electric motors, sensors, and generators.

Corrosion Resistance

While neodymium magnets are generally prone to corrosion, N35UH magnets are usually treated with protective coatings such as nickel, zinc, or epoxy. These coatings enhance their resistance to oxidation and corrosion, making them more durable in challenging conditions.

Applications of N35UH Magnets

N35UH magnets are widely used in the following areas:

High-Temperature Motors

Used in aerospace, power tools, wind turbines, and other motor systems that must operate reliably under high heat conditions.

Sensors

Applied in sensor systems designed for high-temperature environments, providing accurate and stable magnetic field detection.

Generators

Common in renewable energy technologies, such as wind and hydroelectric generators, where high efficiency and thermal endurance are critical.

MRI Machines

Due to their strong magnetic force and thermal stability, N35UH magnets are also utilized in medical imaging equipment like MRI systems.

Thanks to their outstanding performance in high-temperature environments, N35UH magnets are particularly well-suited for applications where thermal stress and heat exposure are common. Their combination of magnetic strength, stability, and durability makes them an essential material in modern engineering, energy, and medical fields.
