Laser Marking on metals

The use of laser marking on metals is now the standard of reference thanks to its speed and precision, while guaranteeing greater brand visibility and continuous traceability of products over time.

For this and many other reasons (such as not requiring any consumables), the laser marking process is becoming more and more popular in many different sectors (Automotive, Valves, Electronics, Mechanical, Jewellery, Medical Technologies and more) .

Whether laser marking for product identification or deep laser engraving, surface blackening (annealing marking) or 3D engraving, the laser marking process on metals offers several advantages:

  • It is an extremely precise and clean contactless procedure that does not require any pre or post-processing.
  • It guarantees product identification and traceability via a high resolution finish
  • Its results are durable and resistant to acids, chemicals and corrosion, without damaging the surface of the material

When the marking oxidizes the surface of ferrous metals (iron, steel, stainless steel) and titanium by local heating of the material, it is called annealing (superficial laser blackening). The oxide layer is usually black, but may also have other shades (eg yellow, red or green). The colors obtained depend on the temperature of the heated layer.
In the melting, the surface of the material remains uniform: the turning is in fact obtained not by removal, but by local heating of the material. On the metal surface the color usually reaches a depth between 20 and 30 μm.


In the case of laser engraving on metals, material is removed from the surface of the component to be processed. This effect can be achieved on almost all materials. Laser engraving is mainly used with metals, plastics and ceramics. The laser beam penetrates the surface and removes it, causing a depression in the area. Since the material is simultaneously heated and reacts to the ambient air, in the engraving areas there is often also a discoloration, which makes the marking even more evident.

Deep marking

Deep laser marking on metals is a highly specialized procedure, where "markings at a given depth" are made in the workpiece. The result is very similar to the mechanical engraving. However, the laser process has many advantages that makes it interesting for industrial use.
In the specific case, in fact, the material is removed in layers so as to be able to also make markings with a radius of a few millimeters, which are difficult to achieve with mechanical methods. Another advantage of the laser is that even particularly difficult-to-machine materials can be marked without problems.
