Permanent Magnets for Sale
When we mentioned permanent magnets, they usually refer to the following several kinds of magnets:
In the beginning of 20th certury , carbon steel, chrome steel and cobalt steel are the main material of magnets. In the 1930s’ Alnico magnets are sucessfully invented, which marks the possiblity of large use of permanent magnets. Then in the 1950s’ ceramic or ferrite magnets are invented. They are rather cheaper than Alnico magnets and the usage of magnets are broaden to high frenquency field. In 1967 Strna with others from US Dayton university successfully realized Smco5, which marked the beginning of the generation of rare earth magnets. Till now, people have invented the second generation –Sm2Co17 and the third generation –NdFeB magnets. Most people would like to buy permanent magnets from China which is the largest supplier of rare earth materials. The people who want to buy permanent magnets will get their magnets with cheapest price but prime quality.
Ceramic or Ferrite magnets are the second generation of magnets. They are made of a composite of powdered iron oxide and barium/strontium carbonate ceramic. Ceramic magnets are divided into two types: Isotropic magnets and Anisotropic magnets. For their low cost of the material and manufacturing methods, they are widely used in electronic component like radio antennas. The most obvious advantage of ceramic magnets is non-corroding, which is used in marine equipments. Different shapes and dimensions of ceramic magnets can be realized by China Polar Metal Coporation Limited.
