What types of metals can be engraved with a laser engraver?

Laser engraving is a versatile process that can mark and engrave a wide range of metal materials. The intense heat generated by the laser beam causes physical changes to the surface of the metal, so metals that can withstand high temperatures are best suited for laser engraving. The most commonly used metals for laser engraving are as follows.

Stainless Steel

Stainless steel is a popular metal for laser engraving because it is highly heat resistant and produces durable, high-contrast marks. Stainless steel is available in different alloys and will produce different color variations when engraved. For example, engraving 304 stainless steel will produce a light gold mark, while engraving 316L stainless steel will produce a dark gray mark.


Aluminum and its alloys, such as aircraft grade aluminum, are lightweight, affordable, and can be laser engraved well. Anodized aluminum produces attractive marks that resist corrosion and scratching. Bare aluminum produces shiny silver marks, but the engraving depth is shallow. Aluminum is best suited for products such as nameplates, labels, gauges, and panels.


Titanium is a strong and durable metal that can be engraved by laser engraver to produce high-contrast silver marks. Laser engraving of titanium produces indented marks, rather than marks produced by melting the surface. Titanium requires very high laser power and relatively slow engraving speeds to produce marks, but it is very resistant to wear and corrosion. Titanium engraving is commonly used for medical tools, automotive parts, and consumer products.


Brass produces a bright golden mark when engraved. The color of the markings may vary slightly, depending on the exact composition of the brass alloy. Brass engraving is suitable for plaques, trophies, jewelry, and other decorative items.


Finally, laser engraving can produce high quality marks on a variety of metals for different applications and uses. With the right choice of metal and the proper laser settings, laser engraving provides a permanent solution for the unique marking and decoration of metal products.
