Laserax has developed laser direct part marking solutions that are specific to the primary aluminum smelter industry. It is an environment fraught with elements that are detrimental to the adequate operations of regular laser engravers. However, Laserax has succeeded in bringing this top-of-class technology to the harshness of smelters, casthouses, die-casters and extruders.
Laserax is also currently bringing its aluminum laser marking and laser engraving expertise to producers of other non-ferrous metals.

The technological feat of marking aluminum and other non-ferrous metals with lasers in such harsh environment was accomplished using lasers that emit at 1064 nm. This wavelength has fairly low reflectivity with many metals including those in this text.
What Kinds of Non-ferrous Metals Can You Engrave with the Right Fiber Laser?

Several non-ferrous metals can be engraved with Laserax's fiber laser marker, find below a non-exhautive list of such metals:
- Aluminum: This metal is widely used in several industries and its applications are numerous.
- Lead: Lead is soft and has a low melting temperature. It is used as X-ray shields, and, of course, in acid-lead batteries.
- Tin: Tin is also soft and has a low melting temperature. It is used as a rust-preventing coating on many materials, such as tin cans.
- Zinc: Zinc is also used for protection against corrosion. It can be found alloyed with other metals for non-structural castings with thin walls and smooth surfaces.
- Magnesium: Magnesium is very lightweight. It’s been used in airplanes for the longest time and is now making its way into cars as the requirements for low weight is gaining ground. It is also found in automotive transmission casings, laptop computers, cell phones and televisions.
- Titanium: Titanium is extremely strong for its weight. At room temperature, it withstands corrosion. It also has low thermal conductivity. It is found in airplane structures, surgical implants and super-alloys.
- Nickel: Nickel is very resistant to corrosion and has low thermal conductivity. It is used as an alloying element. It may be electroplated to protect other metals against corrosion.
The choice of an adequate laser marker for non-ferrous metals is important; however, that’s not the only aspect that needs to be considered. Several other laser parameters need to be optimized to get the best out of your investment.
