Laser metal deep engraving is a common laser processing application, in which the surface of a workpiece is irradiated by a high power density laser beam to instantly melt or vaporize the material for fine engraving. Compared with the traditional metal corrosion process, laser metal deep engraving has the advantages of non-pollution, high precision, and flexible engraving, and is therefore widely used in the metal processing field.
MOPA pulsed fiber lasers cover a variety of power bands in metal deep engraving, you can choose the right laser according to the actual material and processing efficiency requirements, the following information is for reference only.
Aluminum, brass and stainless steel are three common metal materials that each have unique physical and chemical properties. Aluminum is widely used in several industries due to its light weight, excellent electrical and thermal conductivity, high reflectivity and oxidation resistance. The high efficiency of deep laser engraving on aluminum is mainly due to its good thermal conductivity and low melting point. Aluminum is able to dissipate heat quickly under laser irradiation, reducing the heat-affected zone and thus improving processing accuracy and efficiency.
Stainless steel is used in a wide variety of applications for its excellent corrosion resistance and strength. Due to its high melting point and hardness, high laser power and long processing times are required for deep laser engraving.
Brass is favored for its excellent wear resistance, ductility and malleability. However, its high reflectivity of nearly 97% of infrared light and high melting point make it significantly more time-consuming to process.
MOPA fiber lasers feature adjustable power, pulse width and frequency, which can be adjusted to the most suitable processing parameters for different materials, ensuring that the laser always maintains optimal performance.
Laser deep engraving technology has a broad application prospect in the field of metal processing. For different metal materials, it is necessary to choose the appropriate laser according to the specific application requirements and processing conditions, in order to realize the best processing efficiency and effect.
