Stainless steel

About 60-80% of mild steel cutting speed.

Aluminum

Compared to cutting mild steel, cutting aluminum is slower compared due to higher reflection.  Average speaking, the speed of cutting aluminum is about 50-60% of the speed of cutting mild steel .  Often, nitrogen gas is used to get better cutting result.

Copper

Compared to cutting mild steel, cutting aluminum is slower compared due to higher reflection.  Average speaking, the speed of cutting aluminum is about 20-30% of the speed of cutting mild steel .  Often, nitrogen gas is used to get better cutting result.

Glass

Ultrafast pulsed laser is used to cut glass, for example, femtosecond or picosecond lasers). These lasers are ideal for cutting glass because they create minimal thermal stress and produce clean, precise cuts. Be aware that different types of glass have varying absorption rates and cutting specifications.  Higher laser power may create thermal stress and cracking issues. 

     1mm thick glass:   10-50W laser, cutting speed 100-300mm/min

     2mm thick glass:   10-50W laser, cutting speed 50-150mm/min

     3mm thick glass:   50-100W laser, cutting speed 30-100mm/min

     4-5mm thick glass:   50-100W laser, cutting speed 10-50mm/min
