Can a 20-Watt Fiber Laser Engrave Metal?
How Much Laser Power Do You Need To Engrave Metal?
Whether you're engraving marks on tough metals for part identification and traceability or etching intricate logos and designs for branding, the amount of power your fiber laser delivers will directly affect the look and depth of your marks. If you need a fiber laser engraving machine but aren't sure how much power is appropriate for your application, this article will help you determine how many watts your next laser marking machine needs.

20, 50, or 100 watts?
Ultimately, the appropriate laser wattage for engraving metal comes down to these questions:
- Are you marking a soft metal or a hard metal?
- How deep of a mark do you need?
- How quickly do you need to make a mark?
A 20-watt fiber laser is a versatile option, capable of efficiently laser engraving aluminum and other soft metals. A 20-watt laser can also engrave harder metals but it will take longer. More wattage can be beneficial for applications involving hard metals and deep marks.
For deep engraving hard metals like stainless steel, tool steel, nickel alloys, or titanium, a 50- or 100-watt laser can shorten cycle times while still producing clean, durable results. This can help manufacturers in many industries such as aerospace, firearm, aerospace, oil, and gas get the deep marks they need in a reasonable amount of time, improving productivity and efficiency. A more powerful laser also provides long-term flexibility should they ever scale production or expand capabilities.
What Is Laser Power?
Laser power refers to the energy output of the laser beam, usually measured in watts. Simply put, the higher the power, the more energy is applied to the surface you're marking. This makes a big difference in how deep and fast you can mark different materials.
Can You Have Too Much Power?
More power isn’t always better. Using excessive laser power on softer materials can cause burning, melting, or warping. That’s why having adjustable power settings is essential. It gives you the flexibility to fine-tune your system for each material and mark type.
Why Laser Power Matters
- Speed and Efficiency: Higher laser power allows for faster marking cycles, which is a major benefit in high-volume production environments.
- Material Compatibility: Tougher materials like stainless steel and titanium require more power to mark efficiently. Softer metals and plastic require less power.
- Marking Quality: With the right power settings, you get crisp, readable, and long-lasting marks without damaging the surface.
