How Many Types of Metal Could be Cut by Laser?

2022 Best Metal Sheet Cutter Manufacturer uses a high-density laser beam to irradiate the material surface, heating it to thousands to tens of thousands of degrees Celsius in a very short period of time to melt or vaporize, and then the molten or vaporized materials are blown away from the cutting jointing with high-pressure gases to achieve cutting. Laser cutting is widely used in the processing of metal and non-metal materials with the advantages of time-saving, cost-saving, and high-quality results. Useful information on some metal cutting by laser cutting machines is as follows.

1. Carbon Steel

Carbon steel sheets in 20mm can be cut by laser cutting machines. The cutting jointing by oxidation melting laser cutting machine can be controlled at an appropriate width and that of sheet metal can be as narrow as approximately 0.01mm.

2. Titanium and Titanium Alloys

    Pure titanium can be well coupled with a focused laser beam into the heat. Intense chemical reactions occur when oxygen is used as the auxiliary gas. The oxidation layer in the cutting edge is generated and worse overburning although high-speed cutting is efficient. Therefore, it is better to use air as the auxiliary gas to ensure the cutting quality. The laser cutting machine is applied to cut titanium alloy commonly employed in the aircraft manufacturing industry with the benefit of high cutting quality although a little sticky slag at the bottom of cutting jointing is generated, which is easy to remove.

3. Aluminum and Aluminum Alloys

    Aluminum cutting is melted cutting and the auxiliary gas used is mainly used to blow away the molten products from the cutting area to actualize high-quality finishes. For some aluminum alloys, attention should be paid to the prevention of intergranular micro-cracks on the surface of the cutting jointing.
