In bonded Hard Ferrtie material range,flexible rubber magnet is mostly common used.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 andautomated manufacturing techniques not possible with rigid or brittle materials.Flexible materials can be bent, twisted, coiled, punched, and otherwise machinedinto almost any shape without loss of magnetic energy.Flexible magnets are the least expensive by volume and most pliable permanent magnet material when compared to ceramic (ferrite), alnico or rare earth magnets. They perform well in a wide variety of simple applications for home, school, shopand office. They are lightweight, flat, easy to print on and easy to cut with scissors,knife or die. Also, they are ideal for advertising specialties and lightweight holdingapplications. producing area:China
