How to choose magnetic materials?

At present, there are mainly 5 types of magnetic materials to choose from, arranged in order of magnetic strength from weak to strong: rubber magnets, ferrite magnets, aluminum nickel cobalt magnets, samarium cobalt magnets, and neodymium iron boron magnets. The following brief description of the characteristics of each material can help you choose the appropriate magnet.

The material of rubber magnet is very similar to rubber, foldable, curly, and can be cut with scissors. The material color is dark brown, and the surface can also be covered with PVC adhesive paper or coated with glue. Magnets can be made with adhesive on both sides for easy use in handicrafts, sign boards, display boards, magnetic calendars, business cards, telephone books, and other products.

Ferrite is a widely used magnetic material, which is cheap but has stronger magnetic force compared to rubber magnets. The material itself is hard, with a dark gray surface. Circular shape, available in various shapes and sizes such as circular ring, square, tile, etc., is mostly used in handicrafts, suction accessories, toys, motors, speakers, and other products.

Aluminum, nickel, and cobalt are mostly magnetic materials used in the field of technology. Can be used in high temperature environments. After processing, the surface appears as bright as stainless steel.

Samarium cobalt rare earth magnet, the material is very brittle, but it is resistant to high temperatures and can be used at 300 degrees Celsius.

Neodymium iron boron high-performance rare earth magnets are not as brittle as samarium cobalt magnets, but their usage temperature is not as high as samarium cobalt magnets. It is also prone to oxidation at room temperature, so the surface needs to be electroplated. Neodymium iron boron magnets are currently high-performance magnets and are increasingly used in non-technical fields, such as adsorption magnets, toys, jewelry, etc.

Among the five materials mentioned above, each magnet is further subdivided into different grades. You can consult customer service for professional introduction.
