Laser Engraving, Etching and Marking of Metals

Which metals can be laser marked and engraved?

There is hardly any kind of metal that is not capable of being laser marked or laser engraved.

Equally comprehensive are the processing procedures that are used for the identification and engraving of metals:
They range from annealing and black marking to "simple" and three-dimensional engraving.
Laser changeable images can be equally created as decorative surface structures and protecting micro engravings.

A list of metals that can be laser marked and laser engraved is long and includes the following types of metals - but also many more that might not be listed below:

 
Stainless steel
high-grade steel
steel
Carbon steel
Copper
Iron
ferrous metals
Magnesium
Aluminum
Brass
Gold
Silver
Platinum
Paladium
Titanium
