Fiber laser cutting is considered one of the most revolutionary technologies in the metalworking industry. Fiber laser systems feature a wide cutting range and fast cutting speeds and produce precise, high-quality edges. What’s more, fiber laser operating costs are usually half that of a CO2 system due to lower electrical consumption. Fiber laser systems can effectively cut:

Carbon steel (CS)

When the fiber laser cutting machine uses oxygen as the processing gas, the cutting edge will be slightly oxidized. Nitrogen can be used as processing gas for high-pressure cutting.

Stainless steel (SS)

Fiber laser systems machines can effectively cut stainless steel. The cutting speed is dependent on the sheet thickness and the laser power. Cutting speed will increase as sheet thickness decreases and as laser power increases. If the cutting speed is correct, the cut edge will have a regular striation pattern and no dross.

Copper and brass

Both materials have high reflectivity and excellent thermal conductivity. Fiber laser systems are a better choice than CO2 lasers for cutting reflective material. That’s because they have no mirrors that can reflect the laser back to the lens and other optical components. A fiber laser is a solid-state system that eliminates that risk.

Aluminum

Although aluminum has high reflectivity and thermal conductivity, a fiber laser machine can easily cut aluminum with a thickness of less than 6mm.
