Using a fiber laser to mark brass is an increasingly popular choice for businesses who need to label their products. Fiber lasers make excellent marking tools because they are able to engrave brass with high resolution and clarity, they also utilise an extremely small wavelength of light, meaning the mark left on the brass is still small and precise without any blurring or distortions. Unlike traditional etching methods, fiber lasers can mark brass with both visual graphics and textual information. In addition, fiber lasers often require no pre-treatment of the brass surface, meaning they can be used directly on the material with no pre-treatment.

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.

For manufacturers of engineering parts, a good traceability system is a vital part of quality monitoring. The use of laser engraving metal ensures that these traceability marks are permanent and will remain legible for a long time – especially useful for parts that undergo a lot of friction and heat. The types of metals that a laser engraver can be used on are as varied as its applications. A metal laser marker can be used to make permanent marks on stainless steel, soft metals, hardened metals, alloys, titanium, titanium alloys, brass, copper, carbides, high-speed steels, aluminium, anodised aluminium, coated metals, and precious metals such as silver and gold.

Fiber lasers are becoming an increasingly popular choice for engraving rubber. The laser produces a focused and powerful beam of light that quickly and accurately cuts through the rubber, creating clean and precise lines in intricate designs. The use of a fiber laser also produces low heat and produces very little waste, making it an ideal technology for engraving rubber. Additionally, the fact that fiber lasers do not require the use of heavy machinery or tools makes them a popular choice for engraving rubber.

Laser engraving wood can be a great way to personalise wooden surfaces with a unique design or to label items without writing. Laser engraving uses a beam of light to burn shapes and text into a wooden surface. It is precise and can be used on a variety of woods, from soft plywood to hard maple. Laser engraving does not require any contact with the wood surface and is safer than sanding or grinding for certain applications. Laser engraving wood results in a professional look that can add a unique touch to the finished product.
