First of all, from the user's point of view, customers are concerned about a few points is nothing more than the price of magnets, magnets magnetic force and magnets high temperature resistance, the following we are on the market commonly used several magnet materials briefly.
First, according to the price from low to high sorting
1. Ferrite magnets. Because the material is cheap, so the ferrite price is very low, the use of a very large, mostly used in handbag packaging factory, speaker factory, leather products factory.
2. NdFeB magnet. Cost-effective, although it is not the amount of ferrite, but the highest value. All walks of life are involved, our production customers are mostly used in magnetic connectors, DC motors, robots, smart home and other fields.
3. Alnico magnets, more used in military products.
Samarium cobalt magnet. High cost, only in some high-grade permanent magnet motor will be used.
Second, the magnetic force of magnets (magnetic force from strong to weak)
1. Neodymium iron boron. The third generation of rare earth permanent magnet products, the strongest magnet material, known as the industry outside the strong magnet, powerful magnets, magnetic king, etc., the maximum magnetic energy up to 52 megagose Oster.
2. Samarium Cobalt. Magnetic force of NdFeB, samarium cobalt magnets can be processed into different shapes. The maximum magnetic energy is 26 MGauss-Oster.
3. Aluminum nickel cobalt. Weaker than samarium cobalt, the maximum magnetic energy is only 5.4 MGOS.
4. Ferrite. Ferrite and alnico magnetism are very weak, the maximum magnetic energy area is only 3.6 trillion gauss austen.
Third, high temperature resistance (from high to low)
1. Aluminum nickel cobalt. It can withstand 500 ℃ working temperature, is the most high temperature magnet material.
2. Samarium cobalt. 250 ℃ -350 ℃ working temperature choice it is the ideal choice.
Ferrite. Ferrite heat-resistant working temperature upper limit of 300℃.
4. NdFeB. NdFeB is suitable for 80℃-230℃ working temperature, strong magnetic force.
