Characteristics of various cutting materials

Structural steel

When this material is cut with oxygen, it will get better results. When oxygen is used as the processing gas, the cutting edge will have slight oxidation. For plates with a thickness of 4mm, nitrogen 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 more than 10mm, better results can be obtained by using special laser plates and oiling the workpiece surface during processing.

Stainless steel

Cutting stainless steel requires: the use of oxygen, in the case of edge oxidation, does not matter; Using nitrogen, the edges obtained are free of oxidation and burrs, so no further treatment is required. Coating oil film on the surface of the plate can obtain a better perforation effect without reducing the processing quality.

Aluminum (AL)

Although aluminum has high reflectivity and thermal conductivity, aluminum with a thickness of less than 6mm can be cut according to the type of alloy and laser ability. When cutting with oxygen, the cutting surface is rough and hard. When cutting with nitrogen, the cutting surface is smooth. Pure aluminum is difficult to cut due to its high purity, so it can only be cut when the "reflection and absorption" device is installed on the system. Otherwise, the reflection will damage the optical elements.

Titanium

Titanium plates are cut with argon and nitrogen as processing gases. Other parameters can refer to nickel chromium steel.

Copper and brass

Both materials have high reflectivity and good thermal conductivity. Brass with a thickness of less than 1mm can be cut with nitrogen; Copper with a thickness of less than 2mm can be cut, and oxygen needs to be used as the processing gas. Copper and brass can be cut only when a "reflection and absorption" device is installed on the system. Otherwise, the reflection will damage the optical elements.

Synthetic material

When cutting synthetic materials, we should keep in mind the dangers of cutting and the dangerous substances that may be discharged. Processable synthetic materials include thermoplastic, thermosetting materials, and artificial rubber.

Organic compound

All organic cutting has the risk of fire (nitrogen can be used as processing gas, and compressed air can also be used as processing gas). Wood, leather, cardboard, and paper can be cut by laser, and the cutting edge will be scorched (brown).
