A
The most widely used auxiliary gases that can be used by fiber laser cutting machine are mainly air, nitrogen, oxygen and argon. Now I will show you how to use them in different materials.
A.Air
Air can be supplied directly by air compressor. So it’s much cheaper compared to other gases. Although air contains about 20% oxygen, but it’s cutting efficiency is far less than oxygen. Air cutting capacity is similar to nitrogen.
It’s widely used for carbon steel, stainless steel, aluminum, aluminum alloy, copper, brass etc. But if you have high requirements for cutting quality, we do not suggest use air to cut stainless steel, copper, brass, aluminum, aluminum alloy etc cause the air will oxidize the base metal.
B.Nitrogen
It’s widely used in stainless steel, copper, brass, aluminum, aluminum alloy,galvanized sheet etc.
C.Oxygen
It’s widely used in carbon steel etc
3.Argon
The cost of argon is much expensive, it’s widely used for Titanium, Titanium Alloy.
