Why Choose Neodymium (NdFeB) Disc Magnets?

Neodymium disc magnets are part of the rare earth family and are the most powerful permanent magnets available today. Composed of Neodymium, Iron, and Boron, these magnets offer a high energy product (MGOe) in a compact size, making them the standard for:

Precision Engineering: Sensors, hard drives, and MRI machines.

Heavy Industry: Magnetic separators, lifting assemblies, and wind turbines.

DIY & Crafts: Model making, cabinet latches, and invisible fasteners.

Coatings & Durability

Standard Neodymium is prone to oxidation. Our disc magnets feature a Triple-Layer Ni-Cu-Ni (Nickel-Copper-Nickel) coating as standard. For specialized environments, we also offer:

Epoxy Coating: Best for humid or slightly corrosive environments.

Plastic/Rubber Coating: Ideal for waterproof applications and preventing surface scratches.

Frequently Asked Questions:

How strong are Neodymium disc magnets? They are roughly 10x stronger than ceramic magnets of the same size.

Do they lose their strength? Neodymium magnets are highly resistant to demagnetization and will lose less than 1% of their flux density over 10 years if kept within operating temperatures.

What is the max operating temperature? Standard grades are rated for 80°C (176°F). We also stock high-temp (SH/UH) grades for applications up to 150°C.
