Laser marking pure and treated metals and many more
For the processes of laser engraving and laser marking metals, the laser has been doing well for a long period of time. Using a laser marking machine, precise and clearly visible marking can be achieved on most metals from soft metals, such as aluminium to titanium or highly rigid alloys. With certain metals, such as steel alloys, it is likely to implement corrosion-resistant markings without damaging the surface structure by means of annealing marking. Laser marked products are marked with lasers in a diverse range of industries: These applications range from the marking of industrially produced series products for traceability to creating unique promotional items with logos or designs.

Examples of applications
Directional signs, custom gifts and marketing materials are a few examples of metal engraving application ideas that can be personalised using a laser engraver.
Laser marked metal applications are typically used for marking products with traceability features and encryptions. These applications can be found in the electronics and electrical industry, mechanical engineering and tool production, in sheet metal processing, medical field, advertising materials, jewellery and in the locomotive industry.
A special type of annealing marking on metals involves color marking on stainless steel. Based on the technical possibilities with the MOPA laser, reproducible colors on stainless steel can be marked with a laser. For manufacturers of stainless steel products, this provides them with the opportunity to create special color designations, such as a company logo or functional markings like the indication for hot and cold on stainless steel fixtures.
The marking of metals using a laser engraving machine is a very precise and clean form of metal processing. Markings such as serial numbers, data matrix codes and logos can be added to products and components in the highest resolution. The metal marking or engraving is done by the laser, without contact, and requires no pre- or post-processing. The annealing marking ensures a permanent, acid-, chemical- and corrosion-resistant laser marking without damaging the metal surface.

"Trotec Lasers is perfect for the fine detail marking and engraving on metals. It can also engrave on epoxy and powder coating items. Trotec lasers and fine markers produce high quality branding and are very reliable with excellent backup service."- Bea Jeram - Head of Engraving at Umleys -
Examples of applications
Using artistic text, logos or any other artwork; industrial applications, marketing materials and signage can be efficiently and permanently marked using a laser marking machine. The marking and laser engraving of pure and treated metals is a clear and neat form of processing metal. During the process of laser marking metal, cleaning is not needed as the laser is contactless with the material. A chemical- and corrosion-resistant marking can be achieved whilst the metal surface remains undamaged.

Laser marking, or engraving metals has various procedures, depending on the class requirements and material in use. Treated metals, steel, stainless steels, anodized aluminium and other metals can be engraved, marked or refined with a laser beam. These individual methods have distinct advantages and disadvantages.
Metals that are mostly engraved are stainless steel, coated metals and other. During the process of laser engraving on the metal, deep engraving tends to create a visible mark. The engraving causes the removal of the material, thus material evaporates and the colour deviations. The laser engraver releases a powerful energy causing metal materials such as stainless steel, titanium and other metals to be vaporized. Once the engraving is complete, the residual brown colour on the metal can be wiped using further marking processes (i.e polishing).
On titanium and other metals, polishing leaves a white residue. Polishing implies a “lighter” form of laser engraving. The power of the laser is condensed to allow the evaporation of the material. As a subsequent of the polishing, a reduced amount of material is detached and on most of the other materials for example stainless steel, a white marking is created.
During laser marking or annealing, the material surface is not affected due to the nature of the marking process. The material is thus not removed during the annealing marking. When heating the metal, the colour is automatically changed. For instance, the colour of the stainless steel changes at temperatures between 200°C and 300°C and various colours can be achieved with different temperatures. The goal is usually a “perfect black”. Perfect black markings are can be achieved on stainless steel and titanium, but not on other metals. Annealing is also possible on any alloys that contain iron.
The galvo or fiber laser is known as the seamless tool for metal marking to achieve productivity and quality. Pre or post-treatment of the metal is not required, as the outcome of the marking is even and highly detailed.
Uncoated metals can be marked with a CO2 laser engraving machine using only laser marking solutions. The metal marking solution must be applied to the workpiece. It first needs to dry and then will be burned into the material during the laser process. Once the laser process has finished, the excess marking paste must be washed off.
The marking of sensitive surfaces of high-priced workpieces e.g. watches with laser marking sprays is critical due to cleaning. Furthermore, it is important to note that marking solutions are classified as hazardous materials. Thus, the corresponding safety regulations must be adhered to in order to protect your own safety and that of your employees.
