Material

This type of stainless steel (also called Inox) is characterized by a presence of 11% min.of chromium. It is well known for its corrosion resistance, and is often used in industries like surgical instruments, and the food industry (tanks, sugar refineries,..).

Plastic marking applications are numerous in many industries, like household appliances, interior components motor parts in automotive industry, and many others. Mant well known plastics like  PET, PP (Polypropylen), PE, or ABS can be marked, depending on the project requirements using laser, scribing or dot peen technology. 
See sample of dot peen marking on plastic part.

Brass is often used for electrical, plumbing, household applications (valves, locks, handles...) and musical instruments. This material is easy to mark due its softness.
See sample of marking on brass plate.

This material is used in the aerospace industry for the production of strong lightweight parts, in order to reduce global weight of airplanes, and  thus reduce fuel consumption. Titanium is also incorporated in some mass market products like high end sports gear, and other sectors like surgical implants. Laser technology is very efficient and fits with a wide range of material specifications.

Laser tyechnology is best suited for ceramic marking. Hereunder, ceramic teeth mold marked with our fiber laser. Main issue was the size of datamatrix code - very small -to be marked on a concave surface.  

Copper is well known for its use in electrical wires, because the material has two main features: low hardness, and high conductivity. It is also commonly used for plumbing fittings. Hereunder, dot-peen marking used for labeling spare parts for maintenance inventory in railway sector.

We can mark most steel alloys up to the hardest ones (62 Hrc).
This material is used in many industries, such as automotive for car bodies, heavy equipment   like truck and agricultural machines, energy sector …

This material is valued for its low density and resistance. The automotive industry produces large quantity of aluminum parts like motors, and car frames. Aircraft manufacturers also widely integrate aluminum parts  in their designs.
Aluminum is present in many other industries : transportation (trucks, railway cars), construction (windows, doors..), etc...

Obtaining a high quality mark on this material  is challenging because contrast is difficult to create, in comparison with the aluminum after anodizing. 
See sample of marking on aluminium plate before anodizing.

Anodizing increases some fundamental characteristics of the material like surface hardness and corrosion resistance. This treatment is also well known for coloring the aluminum, making parts more attractive for users. The marking operations removes a very thin layer in order to show the core aluminum, providing high contrast .

As the material is coated with a painted layer, adjustments to impact force (dot peen), pressure (scribing) or the speed (laser).
