Laser Processing Brass & Copper with Mactron’s Laser

Brass is mainly composed of trace metal elements such as copper and zinc. It has strong ductility and wear resistance, high electrical conductivity and thermal conductivity, and is often used in industries, jewelry, household and high-tech applications. We can see brass products everywhere in our daily life, such as brass valves, brass water pipes, brass gaskets, brass lamps, circuit boards, precision clocks, house plates, necklaces, commemorative coins, bookmarks, musical instruments, etc.

Both brass and copper are highly reflective metal materials with low absorption at common wavelengths, but can easily absorb laser with a wavelength of 1.06 nm, so that the laser can play the role of energy more effectively. This makes the processing effect of fiber laser marking machines, fiber laser cutting machines and YAG laser welding machines far exceed the traditional method, which is very suitable for processing brass materials.


Laser Marking and Engraving

At present, laser marking and deep engraving are two applications suitable for laser processing brass. The fiber laser marking machine has the advantages of anti-corrosion, anti-wear and anti-fading, it can mark text, pictures and serial numbers on the surface of brass materials, the effect is clear and realistic. It is often used to customize clock instruments, jewelry and bookmarks.

In addition, the emergence of 3D laser marking machines brings finer and more beautiful processing effects to metal deep carving products. fiber 3D laser marking machine removes the brass material layer by layer, and engrave brass products with strong three-dimensional effect and exquisite details, such as medals and plaques.


Laser Cutting

The laser beam of fiber laser cutting machine can quickly melt the surface of the reflective material, interact with the molten metal, quickly and accurately cut out various complex patterns and shapes with high precision, smooth edges, and no deformation. Compared with traditional processing methods, fiber laser cutting machines can cut a variety of metal materials of different thicknesses, including brass, aluminum, stainless steel, carbon steel, galvanized steel, etc., and the fiber laser cutting machine has a wide range of applications and high material utilization, which can effectively save labor and material costs.

In addition, laser cutting brass jewelry necklaces, brass gaskets, craft screens and other brass products has a unique artistic decoration effect.


Laser welding

The thermal conductivity of brass is at least 7 times that of other metals. Traditional electric welding, TIG welding and gas-shielded welding will encounter problems such as melting difficulty and non-fusion of filler material and base metal when welding brass, but laser welding machine can overcome these difficulties well, and its powerful laser beam melts and welds the two pieces of brass together, creating various shapes of brass products with good wear resistance, stability and artistry. Because brass has good electrical conductivity, thermal conductivity and corrosion resistance, it is mostly used to make accessories, mechanical instruments, household items, etc., such as brass water pipes, brass cabinet handles, brass lamps, brass hot pots, brass advertising words.


In daily life, brass materials not only have physical properties such as wear resistance, electrical conductivity, and thermal conductivity, but also brass products processed by laser equipment have the outstanding application advantages of good texture and artistic retro style.


The brass material has a certain degree of reflectivity. Operators need to wear safety glasses when engraving brass, and follow the operating instructions and tutorials to protect personal safety. If you need to know about laser equipment, please leave a message to contact us.


Due to the special properties of brass, parameters and shielding gas play an important role in the process of using laser processing.
