It is difficult to cut this reflective metal with most CO2 lasers below 400 watts. Most brass alloys can be cut up to 400 watts with Kern’s metal cutting system. The thickness of this document is 400%. Brass sheet metal can be processed by both CO2 and FiberCELL lasers.

Can Laser Cut Brass?

Brass can be cut with high-power laser beams because they absorb into the metal. Brass sheets can be cut to a high yield with laser systems, resulting in a reduction in material waste and a better use of materials. Brass can be laser-processed to reduce or eliminate dross with air assist, which makes cutting easier and more efficient.

Can A Co2 Laser Engrave Brass?

Laser engraving of bare metal is not possible. There is only one way to mark it: with a stamp. You can spray a coating on the brass and then engrave it with a stamp. A coating is removed or a marking solution like ceremark is baked on.

Can Co2 Lasers Cut Metal?

Metal can be cut and engraved with industrial lasers. A CO2 laser is most often capable of cutting through steel plates with a power output of up to 100 watts. When compressed gas technology is used, stainless steel and aluminum can be cut with a laser.

What Materials Can Co2 Laser Cut?

The CO laser can be used for a wide range of materials, including wood, paper, cardboard, plastic, PMMA, rubber, leather, metals, and ceramics.

What Materials Cannot Be Laser Cut?



PVC (Poly VinylChloride) /vinyl/pleather/artificial leather

Emits pure chlorine gas when cut!


Emits cyanide gas and tends to melt

Thick ( >1mm ) Polycarbonate/Lexan

Cut very poorly, discolor,catch fire

HDPE/milk bottle plastic

Catches fire and melts

What Metals Can Be Laser Cut?

A laser can cut through many materials, and it is usually used on a few types of metal, such as carbon steel, mild steel, stainless steel, steel alloys, and aluminum.

How Do I Cut Brass?

Metal shears and snips can be used to cut brass sheets. Aviation snips are the type of scissors I use most often. Right-cutting, left-cutting, and straight-cutting are the three types. Each handle is usually green, red, or yellow.

Can You Cut Bronze With A Laser?

You will need a fiber laser cutting system if you want to cut bronze, copper, or brass. Laser cutting bronze with a fiber system offers you exceptional control and detail as well.

Can Co2 Lasers Engrave Metal?

A CO2 laser machine can mark a variety of coated metals, including anodized aluminum and powder coated stainless steel, directly. Pre-treating bare metals with a metal marking compound before engraving with a CO2 laser is possible, such as titanium and nickel plating.

Can I Engrave On Brass?

Almost anything can be engraved with the right tools. It is important to remember that not all materials can be used with ease. There are some who won’t let you cut through so quickly. A strong metal, such as brass, is essential for engraving medals, name plates, and cladding designs.

What Type Of Laser Can Engrave Metal?

Metal laser cutting and engraving should be done with at least 50 watts of Fiber laser power. Direct laser marking of metals can be done with fiber laser power of 40 to 50 Watts. Lasers with a power output of 25 to 150 Watts are recommended for direct metal marking.

Why Can’t A Co2 Laser Cut Metal?

Metal is reflective, and some lasers, including most CO2 lasers, cannot handle the reflected laser back into the emitter of the laser. Because of this, CO2 lasers in the 150-300 W range primarily work on steels that are not too reflective.

What Size Co2 Laser Will Cut Metal?

We at Kern Laser Systems have developed a technology that allows CO2 lasers of 150 to 400 watts to cut metal quickly and efficiently. Using CO2 lasers, thin gauge metal materials such as stainless steel, aluminum, and brass can be processed.

Can A 100w Co2 Laser Cut Metal?

Using a laser cutter with 100 watts, you can cut a sheet of aluminum like butter. Metal fabrication and textiles are industries that commonly use it. Besides cutting acrylic, cardboard, ceramic, leather, wood, granite, marble, and more, it can also be used to cut other materials.

Can A 150w Co2 Laser Cut Metal?

Using a small, 150W laser, stainless steel can be cut with an autofocusing head and gas assist. In general, you will need to set start percentages a little higher and air pressure a little higher in order to achieve this. Lasers with a 150W output use oxygen assist.

What Can You Not Cut With Co2 Laser?

Laser cutting with polycarbonate is not a good idea. Laser cutters are not able to cut ABS well because it is cyanide gas that melts. In addition to melting rather than vaporize, it is more likely to catch fire and leave behind melted gooey deposits on vector cutting grids.

What Materials Are Safe For Laser Cutting?

Materials that can be cut by the laser include wood, paper, cork, and some types of plastic. Almost any material can be etched, including wood, cardboard, aluminum, stainless steel, plastic, marble, stone, tile, and glass.

What Can Co2 Lasers Engrave?

Materials used for engraving laser work include stone, wood, ceramics, tiles, granite, methacrylate, and other materials. A few anodized metals, stainless steel, and sheet. Rubber, cork, papers, and pressed cardboard. Delrin, leather, marble, melamine, rowmark, and glass.

Can Co2 Laser Cut Fabric?

Nonmetal materials such as fabric and textiles can be cut with CO2 lasers, but they are not powerful enough to cut through most metals. Lasers can be used to cut out hundreds of the same pattern pieces or replicate lace designs on multiple types of fabrics, making the process quick and accurate at the same time.
