IMI Raw Materials | Industrial Magnetic Materials & Solutions | Freer Tool

Freer Tool & Supply distributes Industrial Magnetics, Inc. (IMI) raw magnetic materials—professional-grade Alnico, ceramic (ferrite), rare earth (neodymium), and flexible magnetic sheets and strips for custom magnetic assemblies, prototyping, manufacturing, and industrial applications. Available in various sizes, thicknesses, shapes, and configurations (plain or adhesive-backed), these industrial magnetic materials provide engineers, manufacturers, and product designers with high-performance magnetic solutions for sensors, motors, holding fixtures, signage, closures, and specialized magnetic assemblies.

Alnico

Alnico magnet material is an alloy made up of aluminum, nickel, cobalt, and copper, with a roughcast surface that can be ground to close dimensions and to a bright metallic finish.

Ceramic

Ceramic magnet material is a nonmetallic compound of iron oxide, strontium ferrite, and small quantities of other metal oxides. The compound is calcined, wet ball milled to fine particle size, binders are added, then the mix is compacted in a press.

Flexible Magnetic Sheets

Matte white PVC laminated - great for sign making! Conforms to any contour. Can be cut, drilled, or shaped

Flexible Magnetic Strips

Flexible magnetic strips are made of a ferromagnetic powder mixed with a polymer bonding. These high-energy strips resist demagnetization and will not chip, crack or shatter.

Rare Earth

Due to their tremendously high energy level, Rare Earth magnets are ideal for miniaturized applications. They offer high resistance to demagnetization and are recommended for applications with temperature ranges under 200ºF.
