Need to know how thick of metal a fiber laser cutter can cut through? How fast are the speeds with various powers? Here's a guide for beginners and pros alike. In the early days of automatic metal fabrication, business owners typically prefer to buy a primary CNC plasma table or a waterjet cutting machine to roughly cut thick metal, and a fine CNC plasma cutter to precisely cut thin metal. With the needs for manufacturing safety and environmental protection in metal fabrication, YAG and [CO2 laser cutting machines](https://www.stylecnc.com/co2-laser-cutting-machine/ "CO2 laser cutting machines") were introduced on the market, which brought the metal cutting quality to a new level. Moreover, laser is more eco-friendly and safer than plasma and waterjet, and requires no consumables. However, both YAG and carbon dioxide lasers have their own limitations, such as high investment costs, limited cutting thickness, and even the speeds that are not as good as plasma. At this time, a new type of [laser metal cutting system](https://www.stylecnc.com/metal-laser-cutting-machine/ "laser metal cutting system") was launched, which is the fiber laser. It is a professional metal cutting machine. Whether it is quality, speed or thickness, as the laser power changes, it has reached unprecedented heights. The features and advantages of high precision, high quality, fast speed, low cost, ease of use, and full automation make it a unicorn in tube and sheet metal fabrication. Fiber laser cutter is a new type of high-precision metal cutting system that uses a CNC controller to drive laser head to cut metals with the designed layout file to automate metal fabrication in small businesses and industrial manufacturing. From 1mm stainless steel, to over 100mm carbon steel, and even highly reflective metals such as brass, copper, aluminum, gold, and silver, it can easily cut through to create smooth contours with different working gases including air, nitrogen and oxygen. Whether it's sheet metal, tube or special profiles, fiber laser machines has the ability to cut out precise and clean shapes. ![Fiber Laser Cutting Metal Thickness & Speed & Power Chart]() Faced with such a powerful cutting tool, are you wondering how thick of metal it can cut? What are the limitations of cutting speed? How do various laser powers perform in cutting metal thickness and speed? Here is a practical guide for beginners and experts, allowing us to make a detailed analysis from various metal materials, working gases, laser powers, cutting thicknesses and speeds. ### Fiber Laser Cutting Carbon Steel Thickness & Speed & Power Chart Carbon steel is an iron-carbon alloy with a carbon content between 0.02% and 2%. The carbon steels that fiber lasers can cut include low carbon steel (mild steel), medium carbon steel (M2 steel) and high carbon steel (tool steel). Fiber laser cutters can easily cut carbon steels ranging from 1mm to over 200mm at speeds from 0.12m/min to 100m/min, with optional powers starting from 1000W and up to 60000W, and working gas options include air, oxygen, nitrogen and mixed gases. ![Fiber Laser Cutting Carbon Steel Thickness & Speed & Power Chart]() #### Low/Medium Power (1000W -

Brass is an alloy of copper and zinc with high mechanical properties and wear resistance. Lasers can easily cut through brass to make precision instruments, ship parts, electronic components, gun shells, musical instruments, decorations, coins and molds. ![Fiber Laser Cutting Brass Thickness & Speed & Power Chart]() In addition to ordinary copper and brass, fiber lasers also have the ability to cut aluminum bronze, manganese bronze, aluminum brass, gun metal (tin-zinc bronze), white copper and nickel-copper alloy (Monel) with thicknesses from 1mm to 80mm at speeds from 0.4m/min to 65m/min, with laser powers as low as 1000W and as high as 40000W, using nitrogen to cut brass and oxygen to cut copper. ![Fiber Laser Cutting Copper Thickness & Speed & Power Chart]() #### Low/Medium Power (1000W - 4000W) Brass Cutting Parameters | Material | Gas | Thickness (mm) | Speed (m/min) | | | | | | -------- | ------- | -------------- | ------------- | --------- | --------- | --------- | --------- | | 1000W | 1500W | 2000W | 3000W | 4000W | | | | | Brass | N₂ | 1 | 14.0-20.0 | 15.0-22.0 | 20.0-27.0 | 20.0-28.0 | 25.0-30.0 | | 2 | 3.0-4.5 | 4.0-7.2 | 7.7-8.8 | 7.0-13.2 | 12.0-15.0 | | | | 3 | 1.0-1.2 | 1.1-1.5 | 3.0-4.5 | 5.0-7.2 | 5.5-7.7 | | | | 4 | | 1.0-1.2 | 1.3-1.8 | 2.5-3.0 | 3.5-5.5 | | | | 5 | | 0.6-0.9 | 0.8-0.9 | 1.6-2.0 | 2.0-3.5 | | | | 6 | | | 0.4-0.6 | 0.8-1.2 | 1.4-2.2 | | | | 8 | | | | 0.3-0.4 | 0.8-1.0 | | | | 10 | | | | | 0.4-0.6 | | | #### High Power (6000W - 30000W) Brass Cutting Parameters | Material | Gas | Thickness (mm) | Speed (m/min) | | | | | | | -------- | --------- | -------------- | ------------- | --------- | --------- | --------- | --------- | --------- | | 6000W | 8000W | 12000W | 15000W | 20000W | 30000W | | | | | Brass | N₂ | 1 | 30.0-40.0 | 35.0-45.0 | 38.0-50.0 | 40.0-55.0 | 45.0-60.0 | 55.0-65.0 | | 2 | 15.0-18.0 | 25.0-27.0 | 30.0-35.0 | 32.0-37.0 | 35.0-40.0 | 38.0-45.0 | | | | 3 | 12.0-14.0 | 15.0-18.0 | 18.0-22.0 | 20.0-24.0 | 25.0-28.0 | 28.0-33.0 | | | | 4 | 8.0-10.0 | 10.0-12.0 | 15.0-18.0 | 16.0-19.0 | 19.0-22.0 | 22.0-26.0 | | | | 5 | 5.0-5.5 | 7.0-9.0 | 12.0-15.0 | 13.0-16.0 | 17.0-19.0 | 18.5-22.0 | | | | 6 | 3.2-3.8 | 6.0-6.5 | 7.0-10.0 | 9.0-11.0 | 12.0-15.0 | 15.0-18.0 | | | | 8 | 1.5-1.8 | 2.5-3.0 | 5.5-6.5 | 6.0-8.0 | 8.0-10.0 | 10.0-15.0 | | | | 10 | 0.8-1.0 | 1.0-1.5 | 3.5-4.7 | 5.0-6.0 | 7.0-8.0 | 8.0-10.0 | | | | 12 | 0.6-0.7 | 0.8-1.2 | 1.8-2.0 | 2.0-2.2 | 2.5-3.5 | 5.0-8.0 | | | | 15 | | 0.6-0.7 | 1.0-1.2 | 1.3-1.4 | 1.8-2.0 | 2.5-4.5 | | | | 18 | | | 0.5-0.7 | 0.8-1.2 | 0.8-1.3 | 1.3-1.8 | | | | 20 | | | 0.3-0.5 | 0.6-0.7 | 0.8-1.0 | 1.0-1.2 | | | | 25 | | | | 0.4-0.6 | 0.7-0.9 | 0.8-1.0 | | | | 30 | | | | 0.3-0.5 | 0.5-0.7 | 0.6-0.8 | | | | 40 | | | | | 0.4-0.5 | 0.5-0.65 | | | | 50 | | | | | | 0.4-0.5 | | | #### Extra-High Power (40000W) Brass & Copper Cutting Parameters | Material | Thickness (mm) | Speed (m/min) | Power (watt) | Working Gas | | -------- | -------------- | ------------- | ------------ | ----------- | | Brass | 5 | 25.0-30.0 | 40000 | N₂ | | 6 | 20.0-25.0 | | | | | 8 | 18.0-22.0 | | | | | 10 | 10.0-14.0 | | | | | 12 | 8.0-11.0 | | | | | 14 | 6.0-8.0 | | | | | 16 | 5.0-7.0 | | | | | 18 | 4.0-5.0 | | | | | 20 | 3.0-4.0 | | | | | 25 | 2.5-3.0 | | | | | 30 | 2.0-2.5 | | | | | Copper | 3 | 20.0-25.0 | 40000 | O₂ | | 4 | 18.0-20.0 | | | | | 5 | 15.0-18.0 | | | | | 6 | 10.0-15.0 | | | | | 8 | 6.0-10.0 | | | | | 10 | 2.0-3.5 | | | | | 12 | 2.0-2.5 | | | | | 14 | 1.5-2.0 | | | | | 16 | 1.0-1.5 | | | | | 20 | 0.6-1.0 | | | | In short, fiber lasers can cut through metals as thin as 1mm and as thick as 100mm or more, at a speed as slow as 0.05m/min and as fast as 100m/min or more, with laser power ranging from 1000W to 60000W. Different power and working gas will result in various cutting thickness and speed. ### Things To Consider Fiber laser cutting machines are powerful enough to cut popular metal materials with ease and precision, even some highly reflective metals such as aluminum, copper, and brass. However, it is a bit troublesome to cut precious metals such as gold and silver. This requires finding the best power options and working gases, and adjusting to set the right [laser cutting](https://www.stylecnc.com/products/laser-cutting-machine.html "laser cutting") parameters to get the job done smoothly and avoid unnecessary waste. If you want to use gold and silver to cut exquisite ornaments, jewelry, crafts and gifts as well as some precision parts and accessories, feel free to ask STYLECNC's technical staff to get a solution for your business and budget. ### Share This Article With Others ### Further Reading #### Handheld vs. CNC (Robotic) Plasma Cutter: Which is for You? 2023-02-24[Prev Post](https://www.stylecnc.com/blog/handheld-vs-cnc-plasma-cutter.html "Handheld vs. CNC (Robotic) Plasma Cutter: Which is for You?") ### CNC Post Processor Files Free Download 2023-12-04[Next Post](https://www.stylecnc.com/blog/free-cnc-post-processor-files.html "CNC Post Processor Files Free Download") ### Related Topics [](https://www.stylecnc.com/blog/best-fiber-laser-cutters-for-metal.html "Top 10 Best Fiber Laser Cutters for Metal In 2026") 2026-04-179 Min Read #### [Top 10 Best Fiber Laser Cutters for Metal In 2026](https://www.stylecnc.com/blog/best-fiber-laser-cutters-for-metal.html "Top 10 Best Fiber Laser Cutters for Metal In 2026") Explore the best metal laser cutters for every need in 2026 - from home to commercial uses, from hobbyist to industrial makers, from entry-level to pro models.
