Reputation depends on quality,  quality comes from Hard!

Alumina Ceramics:

The anodized aluminum plate is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, and is subjected to electrolysis under specific conditions and an applied current. The aluminum plate of the anode is oxidized, and a thin layer of alumina is formed on the surface. Its thickness is 5~20 microns, and the hard anodized film can reach 60~200 microns. The anodized aluminum plate improves its hardness and wear resistance, up to 250~500kg/mm2, good heat resistance. The hardness of the hard anodized film is as high as 2320K, excellent insulation, and the breakdown voltage is up to 2000V, which enhances the corrosion resistance. It does not corrode in the salt fog of ω=0.03NaCl for several thousand hours. Micropores, which can absorb various lubricants, are suitable for the manufacture of engine cylinders or other wear-resistant parts; the membrane microporous adsorption ability can be colored into various beautiful and beautiful colors. Non-ferrous metals or alloys thereof (such as aluminum, magnesium and their alloys) Etc. can be anodized.
A chemical alumina plate is a process in which an aluminum plate is reacted in a weakly alkaline or weakly acidic solution, and some of the base metal reacts to thicken the surface of the natural oxide film or produce some other passivation film. The commonly used chemical oxide film has a chromic acid film. And phosphoric acid film, they are both thin and good adsorption, can be colored and sealed.

High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
