If you want to make intricate designs on metal, you should consider using a Different types of metal require different cutting processes, so here’s a guide to different materials. This article covers Carbon steel, Stainless steel, Aluminum, Nickel-based superalloys, and more. You can choose the right type of machine for your needs by reading the article carefully. Then, follow the steps below to learn more about how to use your

Carbon steel

While the laser’s power is important to cutting carbon steel, there are certain limitations in its thickness. The 4,000-watt laser can only cut materials up to 3/8 inch thick. For thicker materials, the laser may leave a small, hard-to-remove burr. To solve paint adhesion problems, carbon steel is sometimes processed with nitrogen. This chemical process removes the oxide layer on the material, making it easier to paint.

Stainless steel

A stainless steel metal laser cutter can be used to cut the shapes and dimensions of stainless steel materials. The cutting process is fully automated and begins with focusing a laser beam on a metal surface. This creates a laser that heats the metal and melts it. After the laser beam cuts the metal, the liquefied material is ejected from the cutting area. Then the laser beam cools down, forming the desired shape.


Choosing an aluminum laser cutter is a big decision, as this type of material is particularly reflective. Even non-reflective coatings cannot prevent the metal from reflecting the laser. While a good machine set up can minimize this effect, there is no way to completely eliminate it. While aluminum is known for its heat conductivity, a laser cutting system that uses a high-speed pulse frequency will have better results. A high-speed laser can achieve the melting temperature required for aluminium, thereby minimizing the risk of back reflection.

Nickel-based superalloys

The composition of nickel-based superalloys for metal lathe cutting is a critical issue, and the use of these alloys in laser cutting processes is highly desirable. These alloys provide high corrosion resistance but poor hardness, making them unsuitable for use in high-wear applications. Here’s a look at some examples of nickel-based superalloys and their applications.


Laser cut brass signs have become increasingly popular with companies of all sizes. Beautiful brass signs reflect a company’s professionalism and boost visitors’ trust in the company. Thanks to their high market demand and broad application prospects, brass signs are a popular choice for many types of projects. If you’re a beginner, laser cutting your own company’s brass signs can save you time and money. Plus, brass signs will be durable, bright, and easy to maintain.


Whether you’re looking for a custom copper clock, or a custom copper keychain, you can benefit from a metal laser cutter. Laser cutting metal has several advantages over traditional methods, such as hand cutting, such as tearing or ripping. Laser cutting is also a safer and faster process. Moreover, it produces fine cutting joints, so you can complete intricate cutting works with great precision. Metal laser cutters also feature fine cutting joints, so you can expect precision and quality for your project.

Optical fiber

A high-power fiber optic laser beam is required for cutting highly reflective materials like aluminum alloys, brass, copper, and galvanized steel. With a fiber laser, cutting speeds are high without compromising quality. A fiber laser also features low running costs and can be used with compressed air. The following are some examples of applications where a fiber laser is useful:
