The efficacy of the material without magnets is certainly not the same, what are the Advantages and disadvantages between them. The application of magnets is very extensive, due to the variety of material types of magnets, many buyers do not know how to choose.

First of all, from the user's point of view, the concern is nothing more than the following: (1) price; (2) magnetic size; (3) Temperature resistance; (4) How is the product quality, the following is a brief introduction to the commonly used magnet materials, to help you better determine the type of your own needs when purchasing (if you are still not clear how to choose, you can consult us everbeen, we provide engineering and technical answers and discussion).

First, sort by price from highest to lowest

1, samarium cobalt magnet high cost, only in some high-grade permanent magnet motor will be used.

2, aluminum-nickel-cobalt magnets are more used in military products.

3, NdFeB Magnet cost-effective, although its amount is not as large as ferrite, but the output value is the highest. All walks of life are involved, mostly used in magnetic connectors, DC motors, robots, smart homes and other fields.

4. Ferrite magnet because the material is cheap, so the ferrite price is very low, the amount of use is very large, mostly used in handbag packaging factory, horn factory, leather goods products factory.

Second, the magnetic force (magnetic force from strong to weak)

1. NdFeB The third generation of rare earth permanent magnet products, currently the strongest magnetic force of a magnet material, is known as strong magnetic, strong magnet, magnet king, etc. by outsiders, the maximum magnetic energy product of 52 mega Gaos Auster.

2. Samarium cobalt; The magnetic force is inferior to NdFeB and samarium cobalt magnets can be processed into special shapes. The maximum magnetic energy product is 26 mega-Kauss-Oster.

3. Aluminum-nickel cobalt; It is weaker than samarium cobalt magnetism, and the maximum magnetic energy product is only 5.4 mega Gauts-Oster.

4. Ferrite; It and aluminum-nickel cobalt are very weak in magnetism, and the maximum magnetic energy product is only 3.6 trillion Gaos-Oster.

Third, the temperature resistance (from high to low)

1. Aluminum-nickel-cobalt; It can withstand an operating temperature of 500 ° C and is the most resistant magnetic material to high temperatures.

2. Samarium cobalt; 250°C-350°C operating temperature selection It is ideal.

3. Ferrite; The upper limit of the heat-resistant operating temperature of the ferrite is 300 °C.

4. NdFeB NdFeB is suitable for working temperature of 80 °C-230 °C and has strong magnetism.
