Accurate and efficient to provide the most affordable copper laser cutting price
The laser cut brass machine uses the high-energy heat generated by the laser to melt or vaporize the metal sheet to achieve cutting. Compared with the traditional metal cutting, it has high efficiency and less consumables. Laser cut copper sheet can cut any image and non-contact plate. It can realize complex process cutting.
Brass plates can be seen everywhere in our daily life, ranging from valve manufacturing, water pipes, to connecting pipes of internal and external air conditioners and radiators, etc., mainly because brass has strong wear resistance.
We are a professional brass laser cutting factory, specializing in the production of laser equipment for 15 years, the products are exported to 80+ countries and regions at home and abroad, the products are exported to the United States, South Korea, Russia, Turkey, Saudi Arabia and other countries, and are well received by customers.
Brass laser cut plates is possible. Cutting brass with laser cutter faces two challenges. First of all, copper is a material with good thermal conductivity. The high thermal conductivity requires more laser power when cutting the copper plate, otherwise cracks will easily occur.
Copper is a very reflective metal and can easily reflect laser light, which will have a great impact on the cutting effect. Mastering the pulse parameters of the tunable pulse laser can make the laser penetrate the surface of metallic copper and reflect it to form a melting and cutting process.
By controlling the parameters such as laser power, frequency, pulse width and scanning speed, the cutting copper on laser is feasible and can achieve higher cutting quality and efficiency.

Traditional flame cutting and plasma cutting are not suitable for brass metal cutting brass sheet cut, and flame cutting is only suitable for processing carbon steel. The cutting performance of plasma cutting for thin metal plates is relatively weak.
Laser can cut a variety of materials, such as brass, aluminum, stainless steel, carbon steel, galvanized steel and other metal materials. In addition, the processing effect is better and the application range is wider.
It is better to use nitrogen and oxygen as the gas.
1. Nitrogen: Inert gas, suitable for laser cutting copper plates. It can prevent oxidation and reduce slag generated during cutting.
2. Oxygen: oxidizing gas, which can increase the speed of laser cutting copper plates, and will generate a lot of slag, which needs to be cleaned up in time.
Yes, but it requires specific settings and equipment. Fiber lasers are designed to manage the challenges posed by reflective metals like brass, ensuring efficient cutting without damaging the machine due to excessive back reflection
Copper, brass, bronze, silver, gold, and aluminum are highly reflective to infrared light in the solid state
Dowell brass laser cutting can handle various types of brass, including cartridge brass, yellow brass, and red brass, ranging from thin sheets to thicker plates.
The fiber laser technology used in our machine is specifically designed to reduce the impact of brass’s high reflectivity, ensuring smooth cuts and preventing damage to the laser source.
With minimal moving parts and an efficient cooling system, the machine requires routine cleaning and occasional calibration, typically every 6 months under normal operation conditions.
Brass cutting technology utilizes a focused laser beam that melts the surface of the metal, allowing for clean cuts. The initial piercing stage is crucial, as it establishes the cut when the laser first interacts with solid brass, transitioning to cutting through molten material
Because copper and brass, copper-zinc alloys have low absorption of infrared laser reflective materials in solid state, making these metals difficult to cut.
Pure copper reflects >95% of near-infrared radiation (approximately 1 μm wavelength) in the solid state.
The reflectivity of copper and other reflective metals decreases as the metal heats up, and drops dramatically when the material melts (for example, copper in the molten state drops below 70%).
1. Cutting speed
To prevent the kerf from going out, the process can support about 10–15% support, applying high levels of beam energy on the most reflective materials.
2. Focus position
For piercing and cutting, the focus position is set close to the top surface within reason.
3. Power setting
Use the maximum peak power for piercing and cutting to reduce the time when the material is in its most reflective state.
4. Cutting gas
High pressure oxygen is often used as cutting gas to increase process reliability. Reduce copper oxide reflectivity. For brass, nitrogen works well as a cutting gas.
Reflective metals are metals that reflect wavelengths directed toward them. Such as copper, brass, bronze, aluminum, gold, and silver are the most reflective, the latter can reflect about 95% of visible light. Reflective metals place obvious requirements on laser cutting processes involving laser beams of heat and light. Reflective metal can direct the light that hits it back to its source. This is called “tempering”. If you use a general laser cutting machine to cut forcibly, it will damage the equipment and cause huge losses.
The fiber laser cutting machine focuses the laser emitted from the laser into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the melted or vaporized metal. As the relative position of the beam and the workpiece moves, the material will eventually form a slit, thereby achieving the purpose of cutting.
Applying a non-reflective coating to the metal solves this problem. The molten metal created during laser cutting is itself reflective and will eventually damage the laser. There is also a self-protection system in the laser cutting machine. In the event of a reflection of the laser beam, the system will shut down the laser cutting machine to prevent damage to the lens.
The working principle of the gas (CO2) laser cutting machine is to make the heat of the laser beam fully absorbed by the material, and the reflective properties of the metal will cause the laser beam to be repelled. In this case, the reverse laser beam will enter through the head of the laser cutting machine’s lens and reflector system, causing damage to the machine.
Fiber laser cutting is the cutting edge technology that can effectively handle reflective metal cutting solutions. Fiber lasers use optical fibers that guide the laser beam, rather than using a complex system of mirrors. Fiber laser cutting does not use mirrors, gases, or precision lenses. Instead, it uses optical fiber to transmit the beam, which means that the reflective properties of metal do not cause damage to the laser like with gas or crystal lasers. Using a fiber laser cutting machine instead of carbon dioxide to cut reflective materials is the fastest and most cost-effective alternative.
