Neodymium Disc Magnets

Unmatched strength in a compact shape. These magnets have the highest strength-to-size ratio of any magnet, delivering powerful pull force even in tight spaces. Their flat, round shape creates a strong, even pull across surfaces for reliable holding power. However, they may lose magnetic strength at high temperatures. Also known as rare earth magnets.

Warning: Maximum pull ratings are based on direct contact with rust-free, unpainted iron surfaces. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.

Magnets


	Magnetized Through Thickness

N35SH—These magnets are less likely than other grades to lose magnetic strength when exposed to temperatures up to 300°F.

Magnetized Through Thickness—Magnetized from one flat face to the other, these magnets deliver a concentrated magnetic force. They’re best for direct contact with flat surfaces.

Nickel Plated—With a nickel-plated finish, these magnets stand up to solvents, salt water, and chemicals better than uncoated neodymium. The plating may wear off over time, so these are not recommended for applications with a lot of friction or wear.

Uncoated—Apply whatever finish best guards against rust and wear in your environment. If left uncoated, expect corrosion and less durability.
