brass laser cutting

Using a concentrated beam of high-energy light, a procedure called laser cutting can easily slice through materials like brass. It is possible to use a laser cutter to cut complicated motifs accurately and forms out of brass. The material is heated to its melting point in the laser cutter, and as it advances down the cutting line, the molten material is vaporized. This makes it possible to make sharp angles while minimizing the amount of wasted material and the areas impacted by heat.

Can Laser cut brass?

 Brass can be cut using a laser cutter. Brass is one of the materials that may be cut using laser cutting, which employs a highly concentrated beam of light to make precise cuts. The use of a laser for cutting brass has many advantages, including the ability to cut with great precision and to make elaborate patterns. The equipment is expensive, and the method may not be ideal for cutting heavier brass parts, so there are constraints to consider. To achieve better results during cutting, pre-treatment of the brass may be necessary.

How Brass Laser Cutting Works 

Laser cutting is a very effective and exact technique to carve intricate motifs and forms from brass. Here’s how it goes down:


The brass is positioned directly beneath the laser cutter on a special bed. Once the desired design has been selected, the laser cutter program may generate a cutting path.


A lens focuses the Laser’s light on the brass for cutting. The laser beam is narrow and intense enough to easily cut through the metal.


The intense heat melts the brass from the laser beam. The Laser’s intense heat evaporates a thin tunnel through the metal.


The laser cutter head travels along the cutting path to vaporize the brass. Cut with precision and accuracy, with little to no material waste or areas damaged by heat.


Once cutting is finished, the brass is taken out of the cutting bed. The cut brass may need to have its edges cleaned off and its surface treated before it can be used.

Laser cutting brass and copper challenge

When using a laser cutter on brass or copper, you may encounter problems such as:

  • Reflection

Because of their high reflectivity, copper and brass pose a threat to laser cutting equipment since they can direct the laser beam back to the cutting head. In order to avoid this, the brass or copper may require a protective coating or a reflective substance.

  • Conductivity to Heat

Metals like copper and brass have high thermal conductivity, making them excellent heat transfer materials. As a result, regulating the heat produced during the cutting process may be hard, which might cause the material to bend or deform.

  • Cost

There are additional costs associated with using and maintaining Laser cutting machinery. For some uses, such as when a lot of brass or copper needs to be cut, this might make Laser cutting more expensive.

Fiber laser cutting of copper and brass advantage

Fiber lasers can swiftly cut through materials because they have faster cutting speeds than other lasers. That can be useful in situations where time is of the essence.Fiber lasers are well-known for their minimal upkeep needs. Fiber lasers have a lower total cost of ownership than CO2 lasers because they require less frequent servicing and fewer parts replacements.  Copper and brass are among the many materials a fiber laser may slice. Its versatility allows it to be used in prototypes to full-scale manufacturing. 

CO2 VS fiber Laser cutting brass

Brass can cut with either a CO2 or fiber Laser, and each method has its benefits and drawbacks. A contrast between the two is as follows:


Unlike CO2 lasers, which have slow cutting rates, fiber lasers can swiftly slice through many materials. That can be useful in situations where time is of the essence.


In comparison to other laser technologies, fiber lasers require very little upkeep. Fiber lasers have a lower total cost of ownership than CO2 lasers because they require less frequent servicing and fewer parts replacements. Nevertheless, CO2 lasers have a higher total cost of ownership due to the maintenance and component replacement frequency.

Efficient Use of Energy

Fiber lasers use far less energy than their CO2 counterparts due to their superior efficiency. This has potential utility in contexts where cost-effective energy consumption is essential.

Laser cut brass application. 

The following are some typical uses for brass in laser cutting:

  • Necklaces, bracelets, and earrings with complex patterns may be cut precisely using a laser cutter. Laser cutting is perfect for intricate patterns and forms because of its accuracy and adaptability.
  • Lampshades, wall décor and vases made of brass are very fashionable at the moment. Intricate patterns and motifs may be cut using a laser, giving the products a one-of-a-kind appearance.
  • Electronic components, aircraft, and automobile parts are just a few examples of precise components that may be made with laser cutting. Laser cutting is well suited to producing intricate, tiny parts with high tolerance requirements due to its high accuracy.
  • Horns and trumpets, among other musical instruments, are frequently crafted from brass. Bell pieces and mouthpieces, for example, may be cut precisely and intricately using a laser cutter.

Industries That Use Brass Laser Cutting 

Because of its accuracy, adaptability, and capacity to create detailed designs, brass laser cutting is employed in many fields. The following sectors frequently employ brass laser cutting services:

The Gem and Jewelry Market
