Laser Cutting For Metal Materials

Although almost all metal materials have high reflectivity to infrare wave energy at room temperature,

metal lasers emitting 10.6um beams in the far-infrar waveband are still successfully apply to many metal laser cutting machines.

Firstly, Carbon steel.

Modern laser cutting systems can cut carbon steel plates with a maximum thickness of up to 50mm.

The cutting seam of carbon steel can controll within a satisfactory width by using the oxidation melting cutting mechanism,

and the cutting seam for thin plates can be as narrow as about 0.1mm.

Secondly,stainless steel

Laser cutting is an effective processing tool for the manufacturing industry that uses stainless steel sheet as the main component.

Under strict control of the heat input in the laser cutting process, the heat-affect zone of the trimming can restrict from becoming small,

so effectively maintaining the good corrosion resistance of such materials.

Thridly, alloy steel

Most alloy structural steels and alloy tool steels can use to obtain good trimming quality by laser cutting.

Even for some high-strength materials, as long as the process parameters are properly controll, straight, non-sticky slag cutting edges can obtain.

However, for tungsten-containing high-speed tool steel and hot die steel, there will be erosion and slag sticking during laser cutting.

Fourthly, aluminum and alloys

Aluminum cutting is a melting and cutting mechanism, and the auxiliary gas use is mainly use to blow away the molten product from the cutting area, and usually a better cut surface quality can obtain.

For some aluminum alloys, attention should pay to prevent the occurrence of micro-cracks between the surface of the slit.
