Neodymium Disc Magnet Engineering Data
How to Choose the Right Disc Magnets Grade? (Strength vs. Temp)
Grade selection is about finding the right balance between magnetic strength, cost, and heat resistance.
- Neodymium Disc Magnet Strength Grades: N55 offers maximum strength for miniaturization. N35 provides the best cost-performance for holding applications.
- Neodymium Disc Magnet Heat Grades: Standard 'N' grades demagnetize above 80°C / 176°F. 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 Disc Magnet Coating
Iron in Neodymium magnets rusts easily, so a protective coating is essential.Here is a simple guide to help you choose Disc Magnet Plating.
Nickel Plated Disc Magnets (Ni-Cu-Ni)
Best for: Dry, indoor use in offices, schools, and homes.
Epoxy Coated Disc Magnets
Best for: Outdoor, wet, and marine environments.
Gold Plated Disc Magnets (Au)
Best for: Medical implants, life-long devices, and high-end scientific equipment.
Rubber Coated Disc Magnets
Best for: Outdoor use, vehicle mounts, and protecting delicate surfaces.
Zinc Plated Disc Magnets (Zn)
Best for: Automotive use or dry areas with scratch risk.
Black Nickel Plated Disc Magnets (Ni-Cu-Black Ni)
Best for Hidden, or decorative uses requiring a sleek black finish.
PTFE Coated Disc Magnets (Teflon)
Best for: Medical labs, chemical plants, and low-friction applications.
Plastic Coated Disc Magnets
Best for Waterproof applications, preventing scratches on delicate surfaces.

What Are Neodymium Disc Magnets?
Neodymium disc magnets, also referred to as round neodymium magnets or circular magnets, are thin, flat, circular permanent 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.
Neodymium Disc Magnets Applications
Neodymium disc magnets are incredibly versatile due to their high strength and simple, flat circular shape. They are found everywhere from everyday applications like cabinet latches, luxury packaging closures, and DIY crafts to sophisticated technological systems. As essential components, they drive miniature motors, power speakers and headphones, and enable sensors in everything from automotive systems to consumer electronics. Additionally, their reliable holding force makes them ideal for industrial jigs and fixtures, retail displays, and scientific experiments, making them one of the most widely used magnet types across countless industries.
