    About Magnets
    industrial info icon

    Choose a magnet with the right strength, material, and temperature resistance for your application.

    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.

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

    Neodymium Rectangle 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, rectangular shape creates a strong, even pull across surfaces and fits easily into slots or grooves. 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.

    Nonmarring Encased Neodymium Rectangle Magnets

    These safeguarded magnets grip surfaces without marking them. The rubber-coated case protects metal housings and control panels from scratches and adds friction for a tight grip. It also shields the magnet from cracks and chips caused by drops and bumps. With the highest strength-to-size ratio of any magnet, these deliver powerful pull force even in tight spaces.
    Warning: Maximum pull ratings are based on direct contact with rust-free, unpainted iron plate. Variations in material condition will significantly reduce these ratings. Do not use for lifting over people.
