Analysis of laser cutting of metal materials

 1.Copper and Copper Alloys

    Pure copper (purple copper) cannot be cut with the CO2 laser beam because of its high reflectivity. Only fiber laser cutting machines with specific resistance to high reflexivity can be used. Brass (copper alloys) sheets can be cut by the higher-power laser cutting machine with air or oxygen as auxiliary gases.

2. Nickel and Nickel Alloys

    Nickel alloys, also known as super alloys, come in many varieties. Most of them can be cut by oxidation melting cutting.

3. Alloy Steel

    Most of the alloy structural steel and alloy tool steel can be cut by laser cutting methods to obtain a good quality cut edge. Even some high-strength materials can be cut resulting in a straight, non-stick slag cutting edge as long as processing parameters are properly controlled. However, fusion and slag can occur during the cutting of high-speed tool steel and hot-work die steel containing tungsten.

    With the rapid development of the laser industry, related laser technology and metal laser cutters are also becoming mature. In the field of laser cutting machines, the fiber laser cutting machine for sheet metal processing features low maintenance cost and high cutting quality. Its market share is relatively large compared with the YAG and C02 laser cutting machines.
