With the rapid development of science and technology, fiber laser cutting machines have become more and more widely used in the industrial market. Fiber laser cutting machines have high cutting accuracy and fast speed, which can improve work efficiency by 60% and save more costs. Therefore, they are deeply loved by people.
Now let fiber laser cutting machine manufacturers understand what materials can a fiber laser cut in the industrial market.
Carbon steel plate
After more than 20mm, the carbon steel plate is cut by the oxygen-assisted melting cutting method, and the slit can be controlled within a satisfactory width, and the slit for the thin steel plate can be as narrow as about 0.1 mm.
Laser cutting is an effective processing method for stainless steel plates. It can control the heat-affected zone within a small range, so as to maintain its corrosion resistance. Most alloy structural steels and alloy tool steels can be used to obtain good trimming quality by laser cutting.
Aluminum and aluminum alloys
Aluminum and aluminum alloys cannot be melted and cut with oxygen. The melting and cutting mechanism must be used. Aluminum laser cutting requires a high power density to overcome its high reflectivity to the 10.6um wavelength laser.
The YAG laser beam with a wavelength of 1.06 um can greatly improve the cutting quality and speed of aluminum laser cutting due to its high absorptivity.
Titanium and titanium alloys
Titanium and titanium alloys commonly used in the aircraft manufacturing industry use oxygen as an auxiliary gas. The chemical reaction is fierce and the cutting speed is faster, but it is easy to form an oxide layer on the cutting edge and even cause overburn. It is safer to use inert gas as auxiliary gas, which can ensure the cutting quality.
Most nickel-based alloys can also be cut with oxygen-assisted melting. The reflectivity of copper and copper alloys is too high, basically cannot be cut with a 10.6um carbon dioxide laser.
