Recently, the second phase equipment of Xiamen Sanan Optoelectronics Co., Ltd. was installed and commissioned in place. Xiamen Sanan Optoelectronics officially settled in Torch High-tech Zone in April 2014 with a total investment of 10 billion yuan and 3,000 employees. The first phase of the project has been put into production in 2015 and is now fully operational. The second phase of the project will mainly build LED blue, green light epitaxial wafers and chip production lines. It will be completed and put into production in December 2017 and is expected to reach production within this year. The company purchases the world's most advanced MOCVD equipment, builds a national first-class LED R&D center and experimental center, and promotes Xiamen Sanan Optoelectronics to become the world's leading LED epitaxial wafer, chip, production and packaging application base. The company has a national post-doctoral research station and a national enterprise technology center, and has become the earliest, largest and best quality all-color ultra-high brightness LED epitaxial and chip industrial production base in China. Why do you like to use ferrite magnets? Because it does not rust, does not oxidize, does not corrode and is absolutely environmentally friendly.

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.
