Why Is Alumina Black Color Marking So Famous?

Recent years, the mopa laser marking machine is used in marking black color on the surface of alumina, which has a good effect. Therefor, why is alumina black color marking is so famous? This article, we will introduce the principle of alumina laser color marking machine to you.

The principle of alumina black laser marking machine is used in high energy density of laser focusing, and using special frequency and density and adjusted pulse width to oxidize and change color on the surface of material further in a very short period of time.

And the thickness of membrane directly determines the effectiveness and efficiency of black marking. Generally speaking, the thickness in 10-20um is easy to mark. When the thickness of film is less than 8um, the oxide film is too thin to break, and the white spot appears. It is necessary to increase the pulse frequency and the filling density.

In addition, the surface treatment process of anodic alumina will directly affect the black marking effect. So we suggest that the thickness of anode aluminum film is 10-15 m, then the overall effect will be better.
