What is the difference between laser cutting aluminum plates and cutting steel plates?
The main differences between laser cutting aluminum plates and cutting steel plates are material hardness, processing accuracy, surface quality, and application fields.
Material hardness
Aluminum plate: Aluminum plate is relatively soft compared to steel plate, requiring less energy and faster cutting speed during laser cutting.
Steel plate: Steel plates have higher hardness and require more energy for laser cutting, resulting in slower cutting speed.
Processing accuracy
Aluminum plate: Due to its softness, aluminum plates are prone to vibration and deformation during laser cutting, which affects machining accuracy. Therefore, more precise cutting techniques and higher tool speeds are required to ensure accuracy.
Steel plate: Steel plate has high hardness, relatively stable cutting, and high processing precision.
surface quality
Aluminum plate: Due to its good thermal conductivity, heat can be dissipated faster during laser cutting, reducing deformation and burrs, resulting in better surface quality.
Steel plate: Laser cutting of steel plate will produce large cutting gaps and burrs, and the surface quality is relatively poor.
application area
Aluminum plate: Due to its flexibility and lightweight characteristics, aluminum plate is commonly used in fields such as electronics, communications, aviation, and automotive.
Steel plate: mainly used in industrial structural components, construction, and shipbuilding industries.
Laser cutting characteristics of different materials
Aluminum plate: Aluminum material has a high reflectivity to lasers, and higher energy lasers are required to achieve better cutting results during cutting.
Steel plate: When using oxygen as the processing gas, the cutting edge will slightly oxidize; Using nitrogen can reduce oxidation and achieve better cutting efficiency.
In summary, there are significant differences in material hardness, processing accuracy, surface quality, and application fields between laser cutting aluminum and steel plates. It is necessary to select appropriate processing methods and parameters based on the specific material characteristics.
