As demands for laser cutting machines for industries are increasing, laser cutting equipment is facing new challenges. In particular, the requirements for the process are getting higher and higher, and the upgrading of technology is particularly important. In some industries where laser cutting machines are not in contact, they have started to use fiber laser cutting machines. However, the laser cutting machine is not omnipotent, and is also limited by some materials. As we all know, as the mainstream cutting equipment in the world today, fiber laser cutting machine has become the best choice for cutting various materials due to its wide cutting range, fast cutting speed, good cutting effect and maintenance-free advantages. Especially suitable for cutting metal materials.So what kinds of metal are suitable for fiber laser cutting machines?
