What Are The Differences Between Laser Cutting Machine Cutting Different Metal Materials?

General carbon steel
Low -carbon steels with an iron content of more than 99%are suitable for oxygen -melting laser cutting. The oxidation reaction of iron will generate a lot of heat, which can reduce the energy requirements of laser. In addition, oxygen can be freely entered the melting material through the iron oxidation reaction. Due to the low viscosity of oxidation, it is easy to be blown away by the airflow. Therefore, laser cutting low -carbon steel is high and the incision is smooth.
Stainless steel 
High -pressure nitrogen is generally used for cutting stainless steel, high laser energy, white bright and not oxidized and unchanged, and less hair edges. If it is cut with oxygen, the speed can be faster at the same power, but the incision will be oxidized and black. Considering that stainless steel contains chromium or nickels of different ingredients, different types of stainless steel may require different cutting parameters, and the effects are also different.
Copper material
Copper and aluminum are very similar. The reflectivity of the laser is very high, but red (purple) copper needs to blow oxygen to better cut. There will be hair edges on the back, which is easy to scrape off.
Aluminum
Because aluminum and its alloys have higher reflectivity on laser, higher energy is required to cut better. Cutting can be used with air or nitrogen. The incision is relatively white, but whether it is air or nitrogen cutting, there are a small amount of foam hair on the back, but it is easy to remove.
Nickel alloy
The laser cutting of nickel alloys is similar to stainless steel cutting. However, due to the high viscosity of melting nickel, the slag is more likely to stick to the back of the cut latch, which is easy to produce burrs, and it is usually better cut with oxygen.
Titanium and its alloy
Oxygen cutting will cause severe reactions because the oxidation reaction of titanium releases a large amount of thermal energy. Although the speed is fast, it can easily cause the incision to burn too much. Generally speaking, use air cutting. There are a small amount of hairy residue on the back, but it is easy to remove, so it is easier to control the cutting effect. Nitrogen cutting can also reduce the problem of oxidative pollution, but the thermal effect of the incision can easily change the mechanical properties of the material.
