From the perspective of cost and input, the widely used aluminum laser cutting equipment is fiber laser cutting machine and YAG laser cutting machine. These two equipments are better for cutting aluminum and cutting other materials, such as stainless steel, carbon steel, etc. .
From the experience of laser cutting aluminum materials, the difference between the two is still relatively large, divided into three levels, one is the quality of cutting, the other is the cutting speed, and the third is the production cost (the production cost here is mainly the life of the equipment only) loss).
Cutting quality
Aluminum profiles are highly reflective materials, so neither fiber laser cutting machines nor YAG laser cutting machines can process thicker aluminum. In addition, aluminum materials are not resistant to high temperatures, and burrs are prone to occur during the process of cutting aluminum. Therefore, it is necessary to focus on controlling the process to obtain the desired cutting quality.

2. Cutting speed
The cutting speed also needs to be controlled. Too fast cutting speed is easy to produce burrs, and too slow cutting speed will cause cracks in the aluminum material, which will affect the cutting quality and thus require process control. In general, the laser cutting equipment of the same power, the cutting speed of the fiber laser cutting machine is higher than the speed of the YAG laser cutting machine.
3. Production cost
Laser cutting machines are very inexpensive to process and are lower than other cutting processes. As a comparison between fiber laser cutting machine and YAG laser cutting machine, the cost of fiber laser cutting is lower than that of YAG laser cutting machine. The latter needs to replace laser light fittings frequently, but in the long run, aluminum material is fiber laser cutting machine. The damage of the laser is serious, which greatly reduces the life of the laser. At this point, YAG is lower than the cost of the fiber laser cutting machine.

Also note that aluminum is highly reflective and has low absorption of laser light, so laser protective glasses are required during processing to protect itself.
