Currently there are 5 kinds of magnetic materials to choose from, according to the magnetic force from weak to strong arrangement of rubber magnets, ferrite magnets, Alnico magnets, SmCo magnets and NdFeB magnets.

Here's a brief description of the characteristics of each material to help you choose the right one.

Rubber Magnets Magnet material is very rubbery, foldable, curly, can be cut with scissors, the material color is dark brown. The surface can also be pasted PVC adhesive tape or glue. Each roll up to a maximum width of 75mm, length 100m, the standard thickness of 1.5mm, the maximum width of up to 600mm, length 30m, the standard thickness of 0.5 and 0.75mm. Magnets can be made with adhesive on both sides for ease of use. Ferrite is the most widely used magnet, cheap, but relatively strong magnetic rubber magnet. Material itself is hard, crisp, dark gray surface. Disc shape, ring shape, square shape, tile shape. There are a variety of sizes to choose from handicrafts, adsorbers, toys, motors, speakers and more.

Alnico was first applied to the technical field of magnetic materials. Can be used at very high temperatures - nearly 500 degrees Celsius. After processing the surface was stainless steel bright color. Disc-shaped, cylindrical, square-shaped, horseshoe-shaped and so on. Instruments, meters and high-temperature environment Samarium cobalt rare earth magnets, the material is very brittle, but high temperature, can be used under the conditions of 300 degrees Celsius. Disc shape, ring shape, square shape, tile shape. There are a variety of sizes to choose from High-tech fields and high-temperature environment NdFeB high-performance rare earth magnets, unlike samarium cobalt as brittle, but the temperature is not high samarium cobalt magnets. In the case of normal temperature is also very easy oxidation, so the surface to be plated. Disc shape, ring shape, square shape, tile shape. There are a variety of sizes to choose from NdFeB magnets are the highest performance magnets, and non-technical fields are also more widely used, such as adsorption magnets, toys, jewelry and so on.
