What is Metal Laser Cutting?
Laser cutting involves directing a powerful laser onto the material's surface, like metals, generating intense heat at the illuminated point for precise material transformation. For efficient metal cutting, a laser cutter should have a minimum power supply of 150W to ensure the laser beam has enough strength to cut through the material. It often comes with up to 15 kW of power to cut, vaporize, or melt the materials to create different shapes and forms.
Modern CNC laser cutting machines enhance precision by combining advanced technology with a controlled motion system, allowing the laser head to shape intricate patterns on various metal sheets.
Advantages of Laser Cutting
- Speed: Achieve rapid results as parts are cut in seconds, surpassing alternatives like plasma or waterjet cutting.
- Cost-Effective: The high-speed nature of laser cutting not only reduces production time but also translates to cost savings. Moreover, the low power consumption adds an economical edge to the process.
- Material Versatility: Laser cutting stands out for its ability to navigate through materials with varying hardness, ensuring precision and accuracy regardless of the material's properties.
- Reduced Distortion: Experience minimal material distortion and negligible heat-affected zones, preserving the integrity of the cut materials.
- High Precision & Accuracy: Achieving cuts within a remarkable tolerance of 0.2mm, perfect for cutting thinner parts. This precision significantly minimizes the need for secondary finishing and post-cutting tooling.
- Repeatability: Operate with confidence as CNC-controlled machines ensure consistent, repeatable production runs, promoting reliability in every output.
Metal Laser Cutter: 2 Types of Lasers
When it comes to metal cutting, CO₂ and Fiber laser cutters stand out, each with distinct advantages and considerations. These factors shape efficiency, material versatility, and overall cost-effectiveness. Let’s take a closer look to guide your choice based on specific conditions!
CO2 Lasers
CO₂ laser cutting is a cost-effective method involving the passage of electrical current through a chamber filled with CO₂ gas, resulting in the generation of an intense light beam upon precise focus using mirrors and lenses.
Despite its budget-friendly nature, a noteworthy drawback is its operational efficiency, which stands at only around 20%, with a substantial portion of the generated power converting into waste heat and light rather than actual laser power.
Additionally, CO₂ laser cutting has limitations in its application, particularly in cutting less-reflective metals, as it consistently requires oxygen or nitrogen as a gas assist.
Fiber Lasers
The fiber laser originates from an optical fiber infused with rare-earth elements like erbium, ytterbium, or neodymium. The remarkable progress in their technology expands material processing capabilities more than what CO₂ laser cutters offer.
Primarily used in industrial settings, fiber lasers excel in cutting metal sheets for production components. Compared to CO₂ lasers, their advantage lies in precisely cutting reflective metals such as brass, copper, polished stainless steel, and aluminum.
Another notable feature is their operation without a support gas, ensuring the generation of stable and easily focused laser beams. The most distinctive advantage is their exceptional efficiency, converting nearly 80% of input energy into real cutting power in applications. This not only reduces production costs but also establishes fiber lasers as a dependable and cost-effective choice in laser cutting technology.

When choosing between Fiber and CO2 industrial laser cutters, consider the material requirements, budget constraints, and maintenance considerations.
Fiber is best suited for materials like copper and aluminum, excelling with effective cutting solutions. It showcases higher proficiency when dealing with reflective metals such as aluminum and brass. On the other hand, CO₂ is best for steel and stainless steel but may experience difficulties with reflective metals.
Considering budgetary aspects, while fiber laser cutters have a higher upfront cost than CO₂ counterparts, the maintenance costs differ significantly. CO₂ lasers may incur higher ongoing expenses due to the fragility and alignment requirements of the internal parts.
In conclusion, a Fiber laser generally stands out as a more suitable choice for cutting most materials if with sufficient budgets.
Metal Materials for Laser Cutting
Laser cutting proves versatile for nearly all metallic materials, even the thick ones. As we mentioned before, when cutting specific metals may require a certain type of laser cutter to achieve better results. Other types of non-metal materials can also be laser-cut with the right machines and processes, such as wood, ceramics, paper, cardboard, leather, and certain types of plastics.
Here are the metals commonly cut with lasers in the industrial processes:
- Mild Steel/Low Carbon Steel
- Cold Rolled Steel
- Stainless Steel
- Steel Alloys
- Iron
- Aluminum
- Aluminum Alloys
- Brass
- Copper
- Copper Alloys
- Titanium
- Titanium Alloys
Laser cutting faces a tougher challenge when dealing with reflective metals, for example, brass and copper. Even though fiber lasers can perform well in these cases, cutting other highly reflective metals, including gold, silver, and bronze, can still be more challenging.
