1、 Sort by price from lowest to highest

1. Ferrite magnet. Due to the cheap materials, the price of ferrite is very low and its usage is very large. It is mostly used in handbag packaging factories, speaker factories, and leather product factories.

2. Neodymium iron boron magnet. High cost-effectiveness, although its quantity is not as large as ferrite, its output value is the highest. We are involved in various industries, and our customers are mostly used in fields such as magnetic connectors, DC motors, robots, and smart homes.

3. Aluminum nickel cobalt magnet. More used in military products.

4. Samarium cobalt magnet. High cost, only used in some high-end permanent magnet motors.

2、 In terms of magnetic force (from strong to weak)

1. Neodymium iron boron. The third generation rare earth permanent magnet product is currently the strongest magnetic material, known as strong magnet, strong magnet, magnetic king, etc. by outsiders, with a maximum magnetic energy product of 52 megagauss Oster.

2. Samarium cobalt. Magnetic force is similar to neodymium iron boron, and samarium cobalt magnets can be processed into special shapes. The maximum magnetic energy product is 26 megagauss Oster.

3. Aluminum nickel cobalt. Compared to samarium cobalt, the magnetic force is weaker, and the maximum magnetic energy product is only 5.4 megagauss Oster

4. Ferrite. Ferrite and aluminum nickel cobalt have weak magnetic properties, with a maximum magnetic energy product of only 3.6 megagauss Oster.

3、 High temperature resistance (from high to low)

1. Aluminum nickel cobalt. It can withstand a working temperature of 500 ℃ and is the most high-temperature resistant magnetic material.

2. Samarium cobalt. It is an ideal choice for working temperatures between 250 ℃ and 350 ℃.

3. Ferrite. The upper limit of the heat-resistant working temperature of ferrite is 300 ℃.

4. Neodymium iron boron. Neodymium iron boron is suitable for working temperatures between 80 ℃ and 230 ℃, with strong magnetic force.
