At present, magnet manufacturers mainly have five kinds of magnetic materials to choose from, according to the magnetic force from strong to weak, the order is: neodymium iron boron, samarium cobalt, aluminum nickel cobalt, ferrite and rubber magnet.
The following magnet manufacturers simply analyze the characteristics of each material to help you choose the right magnet:
Rubber magnet
1. Rubber magnetic: The material of the magnet is very similar to rubber. It can be folded, curled and cut with scissors. The color of the material is dark brown, and the surface can also be coated with PVC adhesive tape or glue. Each roll has a width of up to 75mm, a length of 100m and a standard thickness of 1.5mm. The square piece width can reach 600mm, the length is 30m, the standard thickness is 0.5 and 0.75mm, and the magnet can be made into two sides with glue for convenient use;
2, aluminum nickel cobalt: early application of magnetic materials in the field of technology, can be used at very high temperatures (nearly 500 degrees Celsius), after the processing of the magnet manufacturers, the surface is stainless steel-like bright color;
Ferrite magnet
3, samarium cobalt: used in meters and high temperature environment, the material is very brittle, but high temperature resistance, can be used at 300 degrees Celsius;
4, NdFeB: high-performance rare earth magnet, the magnetic force is very high, brittle, it is easy to oxidize under normal temperature conditions, magnet manufacturers will do the plating treatment on the surface;
5, ferrite: has a high magnetic permeability, weak magnetic force, the surface does not need to be coated
