Laser engraving a reflective surface

Made in Britain logo


Copper is one of the few metals that is directly usable in its natural form, or without being combined into alloys. It is characterised by having a very high thermal and electrical conductivity, making it a valuable material in electrical wiring, printed circuit boards, thermocouples, heat exchangers, electromagnets, and electric motors. A fiber can be used to mark any part of the copper with engraving detail that lasts for years as well as having a low power requirement, meaning that it is more energy-efficient than other laser marking systems. As it uses a pulse of light, the heat only affects the copper it is directed at and nothing else, giving it a high level of accuracy.

Copper in Industrial Applications

Laser engraving copper is particularly challenging because of the high reflectivity of the material. In fact, a solid surface made of pure copper will reflect more than 95% of incident near-IR radiation. As with stainless steel, a fiber laser is generally preferred over a CO2 laser when laser engraving copper or to produce laser cut copper. A fiber laser has a wavelength of around 1.07 µm, around 10x smaller than the wavelength of a CO2 laser. Not only will a fiber laser be reflected less than a CO2 laser, but the smaller wavelength allows for a greater power density which makes it easier to penetrate the copper surface.

Copper has excellent workability and lends itself well to processes such as brazing, welding, and soldering. Where increased hardness is desired, copper has been blended with other metals to form alloys such as brass, bronze, and sterling silver, all of which are commonly used to create jewellery.

A particularly useful characteristic of copper is its antimicrobial property. Copper and copper-alloy surfaces have the natural property of destroying microorganisms, making copper an excellent material for doorknobs, handrails, computer keyboards, faucets, and health club equipment. Being a biostatic material, many other forms of life cannot grow on a copper surface.

The Benefits

The laser engraving process can create intricate details and shapes that would be difficult to achieve with traditional engraving methods. Laser engraving copper is also a cost-effective way to create unique and personalized items. It is a permanent process that won't fade or wear away over time. Laser engraving copper is also environmentally friendly, as it does not require the use of any chemicals or solvents. It is also a safe process that does not produce any hazardous fumes or waste.
