Copper and aluminum have high reflectivity and the absorption rate,The laser is irradiated onto the copper or aluminum material, and most of the energy is reflected, and the heat is quickly transmitted to the surroundings.so laser cutting copper or aluminum alloy materials is extremely difficult.
Comparison of laser absorption rates
From the above figure,we can figure that the copper-aluminum material has a very low laser absorption rate near a wavelength of 10 μm,CO2 laser is not easy to cut such this material.
The absorption near the wavelengths of 355 nm and 532 nm is very high, but the laser power is low, so that it hard to cutt these materials;
The wavelength of fiber laser is 1070nm, the absorption of copper and aluminum is higher than CO2 laser, so fiber laser cutter
is best choice for laser cutting for copper or aluminum.
Advantages of laser cutting machine for copper and aluminum alloy
Thin copper and aluminum alloy materials with the thickness of less than 0.15mm can be galvanometer cutting, and the thickness can be processed by head cutting.
