Why don't ferrite magnets rust?
The chemical name of ferrite magnet is iron tetroxide. The main components are: Fe3O4. It is already an oxide of iron, so it is very difficult to be oxidized again. Other magnets (the main component is iron) are made of magnetized metal iron or other elements. Like other iron and steel, they can be oxidized and rusted, and the oxidized part will lose their magnetism.
What are the advantages (advantages) of ferrite magnets
1. Low cost, low price. Raw material cost is cheap.
2. Good temperature stability. It can be used in temperatures of -40 degrees Celsius and +350 degrees Celsius.
3. It is just mentioned that it does not rust.
4. The demagnetization curve is approximately a straight line.
5. Light weight, density is (4.6-5.1) X103kg/M3
6. The anisotropy constant of the magnetic crystal is large.
7. Large coercivity Hc (between AlNiCo alloy material and rare earth cobalt permanent magnet material)
8. High resistivity.
Clean the refrigerator, three secrets, reveal the refreshing refrigerator, at your fingertips.
Summer is coming, the overload condition of the refrigerator is about to begin soon. It is inevitable to clean the refrigerator. What are the coups to clean the refrigerator? The editor provides you with three: First, wipe the seal with a dry cloth soaked in alcohol, which works best. Second, clean the machinery on the back - some include the condenser and compressor surface
