Magnetic Thin Film Material

Ferromagnetic materials, whose thickness is below 1 micron, are called the magnetic thin film materials. They should be attached to the weak magnetic material when used and the magnetic properties of them depend on the preparation methods and process conditions.

There are three main kinds of preparation methods of Magnetic thin film material. The first one is Vacuum evaporation method. That is, under the vacuum condition, depositing magnetic materials with heated evaporation on a substrate. And the second one is electro deposition method. Soon making the magnetic material and the substrate an anode and a cathode, and then depositing the magnetic material working as the anode on a substrate as the cathode, through electrochemical reaction in the electrolyte. And then, the third one is the sputtering method. Using the magnetic materials as the cathode and the substrate as the anode, and then taking inert gas into the vacuum and making the ionization ion bombard the cathode in high speed, and after these processes, the surface of the cathode sputtered atoms will be attached to the anode substrate.

Flexible Rubber Magnet

Flexible rubber magnet belongs to the series of ferrite magnetic material. It is a kind of elastic and twisted magnet, which is compound by bonded ferrite powder and synthetic rubber or plastic and made by the process of extrusion, calendering, or injection molding etc. Soft rubber magnet can be processed into strip, coil shape, flake, block, ring and all kinds of complicated shape.

The surface of soft rubber magnet can be coated by PVC plate, coated paper, double-sided adhesive, UV oil, or color printing. And soft rubber magnets can be cut into any shapes and be affixed to any iron products, so they are suitable to be used in early childhood education materials, auto and motorcycle decorative signs, indoor and outdoor signs warning signs, commodity classification management signs, and so on. And they can be fixed on the refrigerator, safe, metal products like office whiteboard, blackboard and green board in classroom, iron door, shelves and so on. And according to the different needs, they can be made different sizes.
