Trotec Laser Engraving and Cutting Technology Contact Laser marking and laser engraving metal Metals such as aluminum, silver, steel, stainless steel and many more When it comes to engraving and marking on metals, lasers are an effective and efficient tool. Metals of all types, hard or soft, can be marked accurately, legibly, and quickly with a laser. Annealing, with certain metals such as steel alloys, allows for corrosion-resistant marking. Through this process, there is no damage done to the surface's structure, and the mark is permanently applied. This process and more explain why laser metal marking can be useful to a wide range of industries. From marking industrially produced products for traceability to the personalization of promotional items with logos or names, the possibilities are vast. Suitable metals for laser marking and engraving: Stainless Steel Aluminum Anodized aluminum Hardened metals Alloyed steels High-speed steels Titanium, titanium alloys Carbides Brass Copper Precious metals (e.g. silver, gold) Coated metals Would you like more information about laser marking and laser engraving metals?

Color marking on stainless steel A specific type of metal annealing allows for color marking stainless steel; a process utilized by our MOPA laser. This particular laser machine is capable of marking stainless steel with a variety of reproducible colors, providing processors the ability to label their products with color designations. Whether it's for identification marking using company logos, or functional marking using temperature indications, this is a valuable capability to metal processors.

Contactless, permanent metal marking: 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.

There are several methods for marking, etching, and engraving metals. Depending on the material and the quality requirements, aluminum, steel, stainless steels, and additional metals can be engraved, marked or polished using a laser beam. Each method has differing advantages and disadvantages. How does the laser engraving of metals work? Engraving is largely used for processing stainless steel, alloyed metals, and other metals. Engraving or deep engraving, depending on the level of material removal, leaves a prominent marking on the surface. During removal, the material evaporates, and the color changes. Due to the high energy of the laser engraver, materials such as stainless steel, titanium, and other metals are directly vaporized. The brown color that is left behind on the metal can be cleaned using other marking processes (see polishing). How does polishing work? Polishing acts as a lighter form of engraving. In some cases, this process leaves a white marking on particular metals, like stainless steel. The energy of the laser is reduced so that less of the material evaporates, therefore less is removed. How does the laser marking of metals work? During the laser marking or annealing marking process, there is no surface material removed. By heating the metal, however, a color change is achieved. For example, the color of the stainless steel changes at temperatures between 200°C and 300°C. Different colors can be produced at different temperatures. Most mark to reach a “perfect black” color. Perfect black markings are attainable on stainless steel and titanium, but not on other metals. Annealing is also possible on alloys that contain iron. Engrave and mark metals with CO2 or fiber lasers? When it comes to fast, quality metal marking, the fiber laser is the perfect tool. Results are consistent, precise with fine details, and do not require pre- or post-treatment of the metal. It is possible to mark uncoated metals using only a CO2 laser engraving machine and laser marking solutions. First, apply the metal marking solution to the workpiece. Once dry, it will burn into the material during processing. Once the laser process has finished, the excess marking paste must be washed off. It is important to remember that cleaning is essential when marking sensitive surfaces with laser marking sprays. Follow all safety regulations since these marking solutions are classified as hazardous materials. See our lasers in action!
