How deep can laser engraving go on metal?

Lasers can engrave a wide variety of materials such as wood, plastic, metal, etc. The depth of laser engraving on metal depends on a variety of factors, including the type of metal, the laser source and the laser power.

Factors affecting the depth of metal laser engraving

  • The type of metal you use can have a significant impact on the depth of laser engraving. Softer metals, such as aluminum, tend to be easier to engrave and allow for deeper engraving. Harder metals, such as stainless steel, are more difficult to engrave and usually produce shallower marks.
  • The thickness of the metal also affects the depth of the laser engraving, as thicker metals require more laser power to achieve the same depth as thinner metals.
  • The laser source used also has an impact on the depth of laser engraving on metal. CO2 lasers are the most common type of laser used in metal engraving and they usually produce the deepest engravings. Other types of lasers can also be used for metal engraving, but they tend to produce shallower engravings.
  • Laser power is also a factor in determining the depth of metal laser engraving. The higher the laser power, the deeper the engraving depth.


In summary, laser engraving on metal can produce a wide range of depths depending on the type of metal, laser source, laser power, and other factors. When selecting the best laser engraving solution for a particular application, it is important to consider these factors to achieve the desired engraving depth and quality.
