What are the precautions for laser cutting machine processing various metal materials?

Laser cutting machines are more and more widely used in industrial production and can cut most metal materials. Today I will share with you the precautions of laser cutting machines for cutting various metals:

Copper and brass: Both materials have high reflectivity and very good thermal conductivity. Brass with a thickness of 1mm or less can be cut with nitrogen laser; copper with a thickness of 2mm or less can be cut, and the laser cutting gas must use oxygen. Copper and brass can only be cut when a "reflection absorption" device is installed on the system. Otherwise, the reflection will destroy the optical components.

Aluminum: Despite its high reflectivity and thermal conductivity, aluminum with a thickness of 6mm or less can be cut, depending on the alloy type and laser capabilities. When cutting with oxygen, the cutting surface is rough and hard. When using nitrogen, the cutting surface is smooth. Pure aluminum is very difficult to cut because of its high purity. Aluminum can be cut only when the "reflection absorption" device is installed on the fiber laser cutting machine system. Otherwise the reflection will destroy the optical components
