Fiber laser cutting function to cut what metal materials?

Carbon steel.
   The thickness of laser cutting carbon steel plate can be up to 25mm, the use of oxidation fusion cutting mechanism to cut carbon steel joints can be controlled in a satisfactory width range, the thin sheet can narrow to about 0.1 mm.

Alloy steel.
   Most alloy structural steels and alloy tool steels can be laser-cut to obtain good edge cutting quality.When oxygen is used as a processing gas, the cutting edge is slightly oxidized.For plates up to 4mm thick, nitrogen can be used as a processing gas for high pressure cutting.In this case, the cutting edge is not oxidized.For plates with a thickness of more than 10mm, a special plate can be used for the laser and the surface of the workpiece can be oiled in the process to get better results.For high strength steel, as long as the process parameters are controlled properly, flat, no slag cutting can also be obtained.But for high speed tool steel and hot forging die steel with duck, melting corrosion and slag adhesion are easy to occur during laser cutting.

Stainless steel.
   Laser cutting is an effective method for the manufacture of stainless steel sheet.Under the condition of strictly controlling the heat input of laser cutting, the width of the heat affected area of the cutting edge can be limited, thus ensuring the good corrosion resistance of stainless steel.
 

Aluminum and its alloys.
   Laser cutting of aluminum and Mesoporous gold bending: melting cutting mechanism, the use of auxiliary gas is mainly used to blow out the melt products from the cutting area, usually to obtain a better cut quality.For some aluminum alloys, the injection is necessary to prevent the formation of microcracks between the slit surfaces.Aluminum alloys, despite their high reflectivity and thermal conductivity, can be cut to a thickness of less than 6mm, depending on the type of alloy and laser power.When oxygen is used, the cutting surface is rough and hard;When using nitrogen, the cut surface is smooth.Pure aluminum is very difficult to cut and can only be cut if there is a "reflection absorption" device installed on the system, otherwise the reflection will destroy the optical components.

Copper and its alloys.
   Pure copper (red copper) mountain in too high reflectivity, basically can not use CO2 laser beam to implement cutting, cutting brass (copper alloy > should use a higher laser power, auxiliary gas using air or oxygen, can be on the thin plate for cutting.Both pure copper and brass have high reflectivity and very good heat conductivity.Brass of less than 1mm thickness can be cut with nitrogen;Copper with thickness of 2mm or less can be cut. Oxygen must be used for processing gas.Cut pure copper and brass only if there is a "reflection absorption" device installed on the system, otherwise reflection will destroy the optical components.

Titanium and its alloys.
   Pure titanium can well coupling the heat energy transformed by the focusing laser beam. When the auxiliary gas USES oxygen, the chemical reaction is violent and the cutting speed is fast, but it is easy to generate oxide layer at the cutting edge and may cause overburning.Therefore, the use of air as an auxiliary gas can ensure cutting quality access.The titanium alloy laser cutting ball commonly used in aircraft manufacturing industry is better, although there will be a little slag at the bottom of the slit, but it is easy to remove.Titanium sheets are cut with nitrogen and nitrogen as processing gases.

Nickel base alloy.
   Also known as superalloy, there are many varieties, most of which can be implemented laser oxidation fusion cutting, notch quality is good.Laser cutting equipment can be used to cut stainless steel below 4mm. Oxygen can be added to the laser beam to cut carbon steel 25mm thick. However, a thin fluorinated film will be formed on the cutting surface after oxygenated cutting.The size of the cut can be increased to 30mm, but the size error of the cut parts is large.
