Laser engraving of chrome, gold and silver

Chrome laser engraving

Chromium is the solid blue-white metal with the metallic luster sometimes associated with black metals. Thanks to its passivation, chromium is very resistant to air and moisture, i.e. corrosion-resistant. It is electro- and thermally conductive as well as antiferromagnetic . Chromium is one of the most important alloying elements for stainless steels, it gives the steel high durability and corrosion resistance.

In addition, chromium is used as a coating metal for chrome plating (e.g. black chrome plating or bright chrome plating). Chromium compounds are used, for example, for tanning agents, dyes and for refractory materials. Very good results can be achieved with the laser engraving of chrome-plated surfaces .

Laser engraving of gold and silver

Gold is the very heavy and very soft non-magnetic precious metal that is also highly ductile. Gold conductors and galvanic coatings of various surfaces are widely used in microelectronics. Gold is used in many areas (eg in medicine).

Traditionally, the jewelry industry is the largest consumer of gold. The jewelry is not made of pure gold, but of its alloys with other metals, which give the material mechanical strength and durability. Nowadays gold-silver-copper alloys are used for this purpose. Gold jewelery is easy to engrave : wedding rings, watches, bracelets with plaques, necklaces, etc

Silver was one of the first metals used by man. Silver is silvery-white with a yellow, brown or black tint because it oxidizes from the surface very quickly in air. Silver is an excellent conductor of heat and electricity , is fairly ductile, malleable, non-magnetic.

Silver is mainly used in alloys with copper to produce silver objects, coins, etc. that can be engraved. Pure silver is widely used in the chemical industry, the areas of silver application are constantly expanding. It is also used in the production of silver-zinc and silver-cadmium storage batteries.
