Flexible materials offer the product designer a uniquely desirable combination of properties at lower cost than other magnet materials. The flexibility and machinability of these materials permit design innovations and automated manufacturing techniques not possible with rigid or brittle materials.

Flexible materials can be bent, twisted, coiled, punched, and otherwise machined into almost any shape without loss of magnetic energy.

Higher energy flexible materials may sometimes replace Ceramic 1 materials, if close tolerances are not required, and if operating temperatures are below about 250F. Standard grades of flexible materials have energy products from 0.6 MGOe to 1.6 MGOe.

For both methods, the first step is to form a "compound", which is a wet slurry of powder in the binder material.

Extrusion involves squeezing heated compound through a shaped die, cooling the shaped material as it exits the die, and magnetizing the material. The standard grade materials are only magnetic on one side.

Calendering involves squeezing the compound between rollers to compress and flatten it to form a sheet. The sheet is fed through sets of rollers several times until it reaches the desired thickness. It is then slit to the desired width and magnetized. The standard grade materials are only magnetic on one side.

Standard stocked shapes include strip and sheet in the lower energy grades, strip and a variety of punched parts in ring, disc, and bar shapes in the higher energy grades. Non-standard shapes and sizes can be fabricated to blueprint specifications from raw stock. Non-standard profiles of the 0.6 MGOe material can be extruded by fabricating special dies.

Assemblies using metal or other components and magnets can be fabricated by adhering magnets with adhesives to suit a range of environments, by mechanically fastening magnets, or by a combination of these methods. We are able to laminate a variety of standard pressure sensitive adhesives to magnetic strip. Standard adhesives are type "A", for general purpose indoor use, and type "T", for general purpose outdoor use. Type "T" adhesives are formulated for greater resistance to UV effects.

No surface treatments are required to protect against corrosion. We are able to laminate a variety of decorative facings to magnetic strip.

Flexible materials are relatively easy to fabricate: they may be cut, scored, punched, slit, or die cut to shape. We are equipped to fabricate these materials to specification.

Low energy flexible magnets are magnetized with multiple poles on one surface to give greater holding force. Higher energy flexible magnets are magnetized either multiple pole, or single pole on one surface. No special handling precautions have to be taken with flexible magnets since they are relatively weak magnetically, and are not brittle.

Magnetic properties of flexible magnets degrade linearly with temperature in the same way as Ceramic magnets. However, the limiting factor for flexible magnets are the binder materials used to render them flexible: these begin to flow at temperatures of about 250F.
