Lasers are known for producing exceptional results when laser marking and laser engraving metal. Trotec laser engraving machines produce quick, accurate and highly legible markings on soft metals like aluminium and hard metals like steel. Our machines help you to achieve a high-quality result every time, regardless of the metal marking needs.

Both the medical and automotive industries take significant advantage of the corrosion resistant markings we offer by annealing steel alloys.

Suitable Types of Metal for Laser Marking:

  • Aluminium
  • Alloy steels
  • Anodised aluminium
  • Brass
  • Silver
  • Coated metals
  • Copper
  • Stainless steel
  • Hard metals
  • Hardened metals
  • High-speed steels
  • Precious/semi-precious metals
  • Titanium, titanium alloys

Laser cutting and laser engraving machines for metal are available, depending on your personal requirements.

Application Examples for Metal

Metal products are typically laser marked for traceability reasons. Typical industries utilising these applications include; automotive industries, electronic companies, sheet metal processors, medical technology manufacturers, mechanical engineers and tool manufacturers.

  • Product labelling as an anti-counterfeiting measure
  • Functional labels such as size, diameter, etc
  • Production information, such as date of manufacture, batch number, serial number, etc
  • Traceability codes
  • Data Matrix codes for quality assurance
  • Customisation and personalisation of promotional and gift items made of metals,
  • Dataplates

“Why should I buy a laser engraving machine for metal?”

Laser metal engraving and laser etching metal are extremely precise and clean ways to process metals with non-contact, permanent markings. Serial numbers, data matrix codes and logos can be applied as labels to a variety of products with a high-resolution finish. The function of a laser engraver for metal is created by the laser using a non-contact process that requires no pre- or post-processing. Markings produced by annealing are durable against acid, chemical spills and corrosion, and do not damage the metal surface of the item being marked.

Laser Methods for Marking Metal:


Polishing leaves a white mark on stainless steel and other metals. It is considered a ‘lighter’ way of engraving.

The energy of the laser is reduced, meaning less material will be vaporised. The result is less ablation on a steel-like material and a brighter marking. Regarding the parameters this could mean less power and higher speeds that result in less energy per distance and higher frequencies that result in less pulse energy.

Polishing is possible on all metals.


Engraving leaves a tangible mark on stainless steel and other metals. It leads to an ablation of the material on steel parts. The material vaporises and the colour changes.

To achieve ablation, high powers and relatively slow and medium marking speeds are required. The lower the frequency, the higher the possible pulse energy. That means the lowest possible frequency should be chosen for engraving. The brown colour that is left by the burned metal can be cleaned (see ‘polishing’).

Due to the very high energy of the laser, materials like steel and titanium can be engraved directly.


Annealing leaves no tangible mark on stainless steel and other metals. During the annealing process, no material is taken away, meaning there is no ablation. Instead a colour change occurs through the heating of the metal. (Stainless steel changes colour when it reaches temperatures between 200 - 300°C). Varying colours can be achieved with different temperatures.

To anneal metal, it is important to only heat it instead of vaporising it. This can be achieved by reducing the energy density of the laser impact on the steel. To do this, un-focus the laser beam to increase the spot size, as the same energy on a much bigger surface will reduce the energy density. Heating up metal takes time; slow marking speeds should be used.

Annealing is also possible on any alloys which contain iron.
