high performance, the highest price, crisp, excellent temperature characteristics, corrosion resistance.
Aluminum nickel cobalt:
low performance and medium price, excellent temperature characteristics, corrosion resistance, poor resistance to interference.
SmCo magnet, ferrite, NdFeB magnet can be made by sintering and bonding. The sintering magnetic properties are high, the molding is poor, the bonding magnet has good formability, and the properties are reduced a lot.
AlNiCo can be made by casting and sintering. The cast magnet has higher performance, poorer molding property, lower sintered magnet and better formability.
Storage and transportation of magnets:
When the magnet is stored, keep the room ventilated and dry, otherwise, the wet environment will cause the magnet to rust. The ambient temperature should not exceed the maximum working temperature of the magnet.
The non-electroplated product can be properly oil and rust when stored, and the magnetized product should be kept away from magnetic field sensitive objects such as magnetic disk, magnetic card, tape, computer monitor, watch and so on.
The magnet is more brittle. In the process of transportation and electroplating, it is necessary to ensure that the magnets are not subjected to violent impact. If the method is not appropriate, it may cause magnetic breakage and crack.
When the magnet is magnetized, it should be shielded when transporting, especially air transportation must be completely shielded.
During the use of the magnet, the workplace should be kept clean. Otherwise, magnetic particles such as iron scraps can be easily absorbed.
The characteristics of NdFeB material are hard and brittle, and its suction can reach more than 600 times its own weight, which is easy to absorb and damage.
In the process of operation, attention should be paid to avoid breaking and damaging for small specifications. The safety and protection of the human body should be paid more attention to for the larger specifications.
