About Magnets

Neodymium Magnets

Nickel plating gives these magnets good corrosion resistance.

Multi-Pole Neodymium Magnets

Many small poles give these magnets shallower, more concentrated magnetic fields that hold especially well on thin material. They resist temperatures up to 180° F.

Multi-Pole Neodymium Magnets with Unthreaded Hole

Many small poles give these magnets shallower, more concentrated magnetic fields that hold especially well on thin material.

Flexible Magnets

These magnets are made of corrosion-resistant ceramic and bonded with rubber for flexibility.

Conformable Magnets for Irregular Surfaces

Stretch these magnetic strips over corners and irregular surfaces.

High-Temperature Flexible Magnets

Unlike other flexible magnets, these resist demagnetizing at temps up to 250° F.

Center-Aligning Paired Magnets

Attach parts in the same place every time with these magnet pairs that center as they pull together.

Twist-Release Paired Magnets

These magnet pairs attract for a strong hold but repel when twisted for an easy release. Use them on doors, covers, and other parts that need to be repeatedly installed and removed.

Multi-Position Paired Magnets

These magnet pairs rotate into multiple positions to orient displays, sensors, and other devices. They have a firm hold at specific angles, but turn easily without detaching.

Magnetic Latches

Magnetic force holds doors closed.

Magnetic Contact Alarm Switches

Wire contacts to an alarm system to alert when doors or windows are opened.
