Block magnets can be either a rectangular, square or cube. All magnetic blocks have six sides which are at right angles with each other. They are measured according to the Length (L) x Width (W) x Height (H). Our wide selection of block magnets includes many different sizes and grades, as well as different coatings. Some magnetic blocks have countersunk holes so that they can be fastened in place with a screw. We also offer magnetic blocks with self-adhesive backing so that the magnet can be attached to a non-metal surface.
Uses for Magnetic Blocks
Magnetic blocks are are suited to a wide range of applications such as design, advertising, engineering, manufacturing, printing, film, science, construction. Block magnets are also used in multiple commercial and industrial applications, such as water purification devices to capture heavy metals, mineral salts and scale.
AMF Magnets offers four different types of magnetic blocks:
Neodymium Block Magnets, also called Rare Earth block magnets, are offered in several sizes and grades. They are the best choice if you need a magnet with maximum magnetic strength. These super strong magnets are a best seller!
Ceramic Block Magnets (sometimes called Ferrite magnets) are a low-cost but versatile type of magnet widely used in appliance motors. These are medium strength magnets.
Alnico Block Magnets are permanent magnets made from aluminium, nickel and cobalt. They perform well at high temperatures and are very resistant to corrosion.
Samarium Cobalt Block Magnets are composed of samarium, cobalt and iron. Samarium cobalt magnets are valued for their superior strength relative to their size. Even at extremely low or high temperatures these magnets resist demagnetization.
