Fiber laser engraving machine have wide application on metal material process, but what detail material they can do?  Follows let us talk some common fiber laser engraving material.

Fiber laser engraving machine

1. Aluminum

Aluminum is one of the most commonly marked substrates, and we use it in many industries. Typically, with lighter marking intensity, aluminum will turn white. anodized aluminum looks good , but white marking is not ideal for bare and cast aluminum. More intense laser settings provide a dark grey or charcoal color.

Each XT fiber laser engraving machine is capable for aluminum marking. The ideal system for your application depends on your laser marking requirements.  Ablation is the most common marking technique for anodized aluminum, but some people call for etching or engraving.

2. Brass and copper

Brass and copper have high thermal conductivity and thermal transfer properties. So we use it for wiring, printed circuit boards and pressurized flow meters. Their thermal properties are ideal for laser marking systems for metal because the heat is quickly dissipated. This reduces the impact the laser can have on the structural integrity of the material.

Every XT fiber laser engraving machine is capable of marking on brass and copper and the ideal system for your application depends on your marking requirements. The best marking technique depends on the finish of the brass or copper. Smooth surfaces can offer a soft polished marking affect, but also can do annealed, etched, or engraved.  Etching or engraving is best in order to provide readability by humans and machines. In some cases a dark anneal can work, but surface irregularities can cause reduced readability.

3. Tungsten and Carbide

Tungsten and Carbide are two of the hardest metals on earth and are widely used in tooling and cutting applications. Another popular segment for these substrates is wedding bands for men. Tungsten and carbide are receptive laser marking metals and laser engraving metals.

Each and every XT Laser series is capable of marking on tungsten and carbide and the ideal system for your application depends on your marking requirements. Because these metals are so hard, so we don’t recommend etching or engraving. For carbide, because of the darker color it naturally has, getting a contrasting mark is rather easy with even light laser intensity. A white color is most common when polishing or annealing carbide and the contrast is extremely good.

4. Non-semiconductor ceramics

Non-semiconductor ceramics come in a variety of shapes and forms. Some are very soft and others are hardened providing a lot of variety. In general, ceramics are a difficult substrate to laser mark as they do not typically absorb a lot laser light or wavelength.

Certain ceramics 532nm Green laser marking system that is better d by . We recommend you have test sampling done to determine the best marking technique to apply to your ceramic material. Ceramics that can be marked are often annealed, but etching and engraving are sometimes possible, too.

5. Chrome

Chrome plating provides a stylish and sophisticated finish, and usually requires minimal laser intensity to remove or get through the plating. we need take ensure the marking happens on the surface only, with no impact to the chrome plating.

Each and every XT Laser series is capable of marking on chrome plating and the ideal system for your application depends on your marking requirements. We have found that lower powered, faster pulsing lasers yield the best results. Anneal or polish to protect the plating. The annealed marking is black and the polished marking is white.

6. Coated and Painted Metal

Usually we protect metals from corrosive elements through many different coating. Some coatings are thicker and require more intense laser settings to completely remove, such as powder coat. Other coatings are thin and can only protect only the surface, such as black oxide. These are much easier to ablate and will provide great contrast marking.

Each and every XT Laser series is capable of marking on coated and painted metals and the ideal system for your application depends on your marking requirements. The UM-1 provides plenty of power to remove or ablate thinner coatings. It may not be ideal for removing a powder coat but it can easily mark a powder coat. Our more powerful fiber lasers come in 20-50 watts, and can easily remove the powder coat and mark the underlying surface. Our fiber lasers can ablate, etch and engrave coated metals.

7. Fiberglass & Carbon fiber

Fiber laser engraving machine based materials like fiberglass have mark limitations. Because they are composed of individual fibers, laser may damage the structural integrity, resulting in a blurry marking.

Carbon fiber is easier to mark, as the laser typically does not threaten the integrity of the material. Howere the composition and color of the carbon, so the resulting laser mark is always black, which limits contrast and readability.

Each and every XT Laser series is capable of marking on fiberglass and carbon fiber and the ideal system for your application depends on your marking requirements. Higher wattage lasers can etch or engrave more quickly, but the lower wattage laser can perform the same markings with an extended cycle time. So the 532nm Green lasers are a good choice because they don’t cause a lot of melting.
