The process of laser engraving or marking is one of the most preferred ways of inscribing on metal surfaces, where in a focussed beam of laser light is used to carry out the process. While this process can be implemented on various materials surfaces, there are certain materials that may not be so suitable as well. Material surfaces that are fragile and sensitive to lasers cannot be subjected to lasers. However material surfaces that are durable and tolerant to lasers can be successfully used to carry out the task of laser engraver and marking. Naming a few material surfaces that are commonly used, Aluminium both anodized and non-anodized, Stainless Steel are the ones that are extensively preferred, but all the same magnesium and lead also can be categorised as the metal surfaces that are suitable for the job.

A deeper review reveals why these metal surfaces are considered as ideal surfaces for laser engraving and marking. Aluminium is such a metal that is very widely used in fabricating vehicle crankcase and body parts in the automobile sector. With a comparatively high thermal conductivity, aluminium metal can sustain ...
... substantially high temperature variations and due to the naturally light colour of the metal surface laser engraver can make remarkable contrast markings which are quite conspicuous and visible easily. Stainless steel is the other metal that can be categorised as a metal that is one of the strongest materials, and can hence withstand the laser treatments to a great extent without the loss of properties or getting disfigured easily.

Along with the process of laser etching and engraving, the process of annealing laser on the material surface of steel also offers corrosion resistance, when we consider rust as one of the biggest killer of steel surfaces or the material as a whole. Steel tubes, sheets and other steel items can effectively endure to the process of laser engraving.

The metal magnesium is one such metal where the industrial sector mostly makes use of in the fabrication of auto parts that have to be lighter I weight. Generally spares like the gearbox parts, steering wheels of cars, engine casings and similar are those parts which contain a known percentage of magnesium to render the parts light in weight. Laser engraving works best in this metal surface thereby making it one of the preferred metals for laser marking and engraving. Lead is another metal that is subjected to laser engraving and etching or marking, in the industry.

Since the metal lead has a comparatively lesser thermal conductivity amongst the other preferred metals, heat generated during the process does not disassociate to the atmosphere or the surrounding, on the other hand it remains on the material surface, making it the fastest of the metal surfaces that can go on with the laser marking, etching and laser marking process. Companies like Signvec technology, with more than two decades of rich professional experience in the manufacture of laser marking machines, laser etching and laser engraving machines, provide second to none services in the mentioned sector.
