Metals are suitable for both CO2 laser engravers and fiber laser engravers, and they are prevalent in the laser processing industry. However, CO2 laser metal machines cannot directly engrave metals; they can only engrave the coating layer on metals. On the other hand, fiber laser engraver can directly engrave the surface of metals, such as with fiber marking machines, which enable direct engraving on metal surfaces. Laser engraving can create delicate and intricate patterns and text on metal surfaces. It can provide quiet and efficient operation in CO2 And Fiber Laser engraver for metal.
The metal laser engraving ideas you can create
The fiber laser engraver for metal offers high precision and efficiency in engraving complex metal patterns, which is necessary for etching metal jewelry. Customized wedding souvenirs symbolize everlasting love. Metal jewelry gifts with special meanings will always be in demand.
Anodized Aluminum Business Cards: Very cool and represent high-end talents, making them stand out. Do not underestimate the requirement of laser-engraved metal business cards in the workplace, but the key is does it have an added value effect on worker.
Industrial Metal Part Marking: Industrial metal parts often need logos, QR codes, or text, representing exclusivity, and copyright, and enabling customers to scan for information. Metal parts with logos and QR codes made in metal laser engraver instill more trust in customers, leading to more orders.
Open a Custom Metal Product Store: Offer customized trophies, keychains, nameplates, metal watches, firearms, knives, pens, USB drives, bottle openers, and other metal promotional products. And just need a fiber laser engraver for metal.
Which metal product can be processed with a cnc laser engraver?
With fiber laser marker
• We commonly used metals for fiber marking machines are aluminum, brass, stainless steel, and gold.
• Brass is often used for high-resolution serial numbers, data matrix codes, and logos marking.
• Stainless steel is generally marked with fiber laser engraver for metal, and special types of annealed stainless steel can be color marked. Gold, being a precious metal, is often used in jewelry or decorative items, and its soft texture allows for direct laser processing.
With CO2 laser engraving metal machine
• Metals commonly engraved with CO2 laser metal engraving machines are anodized aluminum and coated metal products.
• Anodized Aluminum: Anodized aluminum sheets form a dense oxide film on the surface, and laser marking on anodized aluminum leaves no residue. Depending on the color of the anodized layer, it can present significant contrast and beautiful, intricate engravings.
• Metal Coatings: a CO2laser machine for metal can accurately engrave metal coatings, enabling various colors on the metal surface, providing strong contrast compared to the metal itself.
To Find a better laser metal engraver
When seeking a metal laser engraver that meets your requirements, look for a reliable provider like Thunder Laser.

The common parameters for engraving metal
Cutting effects depend on the material itself. Even for the same thickness and type of metal, differences in origin, batch, and production methods may result in variations, affecting the cutting effect.
These are the parameters for some metal laser engraving in fiber laser engraving machines, and you can adjust secondary to achieve suitable results.

Tip for laser engraving metal
To obtain a color laser engraving on metal stainless steel in fiber marking machine
First, use a handheld sander to polish the stainless steel surface to ensure consistent smoothness of the metal surface.
Next, use different powers to carve stainless steel in the fiber laser engraver for metal.
You will find that stainless steel undergoes different color changes at the same power and speeds in metal engraver laser, so this characteristic can be used to carve colored patterns.
Why can co2 laser machines carve anodized aluminum oxide?
CO2 metal laser machines generally cannot engrave metals because the laser is reflected by the metal, making it unable to achieve the desired engraving effect. However, anodized aluminum has a dense oxide film on its surface, and the laser mainly engraves this oxide layer rather than directly contacting the aluminum material itself. Therefore, a CO2 laser etching machine for metal can create engravings with solid contrast and exquisite patterns.
How to laser engraving stainless steel to achieve black on surface?
Thunder Laser’s fiber laser engraver for metal can engrave black patterns on stainless steel. If you only have a CO2 metal laser engraving machine, there is also an interesting way to achieve this.
You can coat the stainless steel bottle or spray paint it and then laser engrave metal in a CO2 laser engraving machine for metal.
To achieve black patterns, you can spray molybdenum dry lubricant three times, wait for 15 minutes for it to dry, and then proceed with laser engraving. Excess black lubricant can be cleaned with water, but using lacquer thinner for cleaning is more efficient.
