Analysis Of Laser Cutting Materials

Structural steel
This material will yield better results when cut with oxygen. When using oxygen as the processing gas, the cutting edge will slightly oxidize. For plates with a thickness of 4mm, nitrogen gas can be used as the processing gas for high-pressure cutting. In this case, the cutting edge will not be oxidized. For plates with a thickness of over 10mm, using special plates for lasers and applying oil to the surface of the workpiece during processing can achieve good results.
Stainless steel
Oxygen can be used when cutting end face oxidation is acceptable; Using nitrogen to obtain edges without oxidation or burrs eliminates the need for further treatment. Coating oil film on the surface of the board will achieve better perforation effect without reducing processing quality.
aluminium
Despite its high reflectivity and thermal conductivity, aluminum materials with a thickness of less than 6mm can be cut, depending on the alloy type and laser capability. When cutting with oxygen, the cutting surface is rough and hard. When using nitrogen, the cutting surface is smooth. Pure aluminum is very difficult to cut due to its high purity, and can only be cut when a "reflection absorption" device is installed on the system. Otherwise, reflection will damage the optical components.
titanium
Titanium plates are cut using argon and nitrogen as processing gases. Other parameters can refer to nickel chromium steel.
Copper and brass
Both materials have high reflectivity and excellent thermal conductivity. Brass with a thickness of less than 1mm can be cut with nitrogen gas; Copper with a thickness of less than 2mm can be cut, and the processing gas must be oxygen. Copper and brass can only be cut when a "reflection absorption" device is installed on the system. Otherwise, reflection will damage the optical components.
