How Laser Engraving Metal Work?

The heart of the process is a laser, an intense beam of light, powerful enough to erode metal from the surface. When the laser hits the metal surface, it is absorbed by the metal. They use that energy, and vaporize, leaving an engraved mark on the metal. In chemical terms, this process is called as sublimation as the metal directly moves to the gaseous state from the solid state.

The laser beam intensity (power) is variable and controlled by laser engraver software. It changes that intensity based on the design requirements. The laser strikes with more intensity on areas where deeper engraving is to be achieved.

In some metals, we observe vivid colors after engraving. Color laser engraving is a result of the reaction between the protective coating (oxide layer), such as on stainless steel, with the laser beam. The colors vary based on the metal type, speed, and power of the laser. In uncoated or pure metals, you may not observe these results.

What Metal Can Be Laser Engraved?

FAOs on Laser Engraving Metal

Can Laser Engrave Any Metal?

Nearly all metals like iron, steel, copper, gold, platinum, titanium, and aluminum are suitable for laser engraving. The ease with which each metal can be engraved varies, but generally, they can all be marked with a laser.

What Metal is Best for Laser Engraving?

Laser engraving is well suited for metals that absorb the laser light well and vaporize quickly. Many metals such as copper, stainless steel, iron, gold, and platinum can be laser engraved. But among them, aluminum is considered the best for laser engraving. It has relatively low melting and vaporization points, which allow it to absorb the laser energy and vaporize more readily than other metals.

Will Laser Engraved Metal Rust?

Laser engraving may lead to rust on metals like stainless steel if the process removes the protective chromium oxide layer. However, with careful setting of the engraving parameters, you can avoid damaging protective layers. You can also apply an anti-rust coating after engraving to prevent corrosion.

Is Laser Engraving on Metal Permanent?

Laser engraving creates a durable and permanent mark on metal surfaces. Although metal can wear down over time, the engraving will remain visible for the lifespan of the item, as the laser alters the metal’s surface to create the design.

What's the Difference between Laser Engraving, Laser Etching and Laser Marking Metal?

In the realm of creating marks on metal, there are three primary methods to choose from: laser engraving, laser etching, and laser marking. Beginners usually get confused because these words are used interchangeably. Each technique has its advantages and limitations, making it essential to understand their differences before selecting the most suitable method for your specific application.

Laser Engraving Metal

Laser engraving involves using a high-power laser beam to increase the metal surface's temperature beyond its boiling point, causing the material to change from a solid state directly to a gas through a process called sublimation. As the surface material evaporates, it leaves a cavity, creating a deep, visible engraving with a 3D surface that can be seen and felt. 

This method provides excellent precision and accuracy, making it ideal for intricate designs, small text, and detailed graphics. Laser engraving metal is widely used for various applications, such as personalizing jewelry, creating custom awards, and marking industrial components.

However, metals have high boiling points due to their tightly packed molecules, with melting temperatures often exceeding 1000ºC and boiling points surpassing 4000ºC. To laser engrave metal, a powerful laser engraving machine specifically designed for this purpose is required. These machines utilize high-energy pulses to rapidly increase the metal's temperature. Low-energy, hobbyist, or DIY laser engravers cannot directly engrave metal, but they can be used for metal etching or marking.


  • High precision and accuracy
  • Permanent and durable marks
  • Suitable for intricate designs and small text


  • May require a coating or pre-treatment for certain metals

Laser Etching Metal

Laser etching differs from laser engraving as it does not vaporize the metal. Instead, it melts the upper microsurface of the material, causing oxidation and a change in the original color. Laser etching metal can be done with laser engravers of lower power level at 5w~15w. 


  • Faster process compared to laser engraving
  • Can be done with less powerful laser engravers
  • Suitable for creating high-contrast marks


  • Less durable than laser engraving
  • Marks may fade over time

Laser Marking Metal

Laser marking is similar to laser engraving in that it creates permanent marks on the metal's surface. However, some experts differentiate between laser marking and laser engraving based on penetration depth. In laser marking, the penetration is not as deep as in laser engraving.


  • Creates permanent marks
  • Suitable for various applications like logos, ID numbers, and QR codes


  • Penetration is not as deep as laser engraving
  • Not as suitable for creating depth or texture

Is Laser Etching Metal the Same as Laser Engraving Metal?

We have explored the concept of metal laser engraving, which involves removing particles from a metal surface through the use of high-energy pulsed lasers. These powerful laser pulses are capable of rapidly increasing the metal's temperature to its boiling point, causing the material to evaporate and leave behind a permanent cavity known as an engraving.

A laser engraver that can produce such high-energy pulsed laser is the most versatile and efficient method for metal engraving. In contrast, continuous-wave laser engravers do not have the peak power necessary for this purpose. 

Laser etching, on the other hand, relies on continuous-wave lasers to provide just enough energy to oxidize the metal surface, creating an oxide layer in the presence of oxygen. This oxide layer has a different color, resulting in a distinguishable mark on the surface.

One of the key advantages of laser etching metal is the ability to achieve multiple colors on the metal surface. The color outcome depends on both the metal type and the applied laser beam wattage. By adjusting the wattage, various colors can be obtained, making metal laser etching an attractive option for decorative purposes.


Laser engraving on metal offers a world of possibilities for businesses, hobbyists, and artists alike. With the ability to create intricate designs, permanent markings, and personalized items, metal laser engravers have become an essential tool in various industries. By understanding the different types of laser engravers, such as fiber, CO2, diode, and infrared lasers, you can choose the right machine for your specific needs and applications.
