Laser Engraving And Marking: Metals That Are Mostly Preferred For The Job
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.
