Common laser cutting materials and cutting techniques

Stainless steel

Stainless stee

In theory, a 6000W laser can cut 16mm stainless steel. This thickness is achievable, but it is not recommended for long-term mass production, which is not conducive to the sustainable use of laser cutting machines.

Stainless steel has the characteristics of high hardness, rust resistance, corrosion resistance, and has a wide range of applications. The processing requirements for stainless steel are not the same. Laser cutting machine processing stainless steel greatly improves the processing accuracy and processing quality, and saves the time for secondary processing. , Less waste, high utilization rate.

Laser cutting stainless steel generally chooses to use nitrogen-assisted cutting, which can effectively avoid yellow burnt marks on the surface of the stainless steel after cutting, and achieve the desired effect. In addition, when cutting a circle, the effective diameter of the small circle of stainless steel is 1 of the thickness of the plate. -1.2 times, pay attention to the diameter of the smallest round hole during processing to avoid invalid cutting.

carbon steel

Compared with stainless steel, the laser cutting machine can do more for carbon steel. In theory, a 6000W laser can cut carbon steel with a thickness of 25mm. Although mass production is not recommended, carbon steel with a thickness of 20mm and below can be cut with confidence, and The effect is better.

When cutting carbon steel, nitrogen-assisted cutting is generally used for 1mm and below, and oxygen is the best for 1mm and above, because thicker carbon plates are faster and more efficient under the combustion of oxygen. In addition, it should be noted that the smallest circle diameter for cutting carbon steel is 1.5 times the plate thickness.

Copper and aluminum


Copper and aluminum are all highly reflective materials in nature, especially red copper, and rash cutting will result in greater power loss of the laser. Therefore, it is not recommended to cut high-reflection materials for a long time. If there is a need for batch cutting, IPG should be the first choice when choosing a laser. It has obvious advantages when cutting high-reflection materials, has its own protection mechanism, and will not cause loss to the laser, so it can be used with confidence.
