What Type of Laser Cutter Do You Need to Cut Metal?

Choosing the right laser cutter for metal depends on several factors, including the material type, thickness, and cutting requirements. But how do you decide what type of cutter you need? Let’s break it down.

For metal cutting, fiber laser cutters are the most efficient option due to their high precision and ability to cut through various metal thicknesses. When selecting a machine, ensure the laser source and power meet your production needs.

When selecting the right laser cutter for metal, it’s essential to understand how different machines work and what they are best suited for. The two main types of lasers used for cutting metal are CO2 lasers and fiber lasers¹. Here’s a more in-depth breakdown of both types:

CO2 Laser Cutters

CO2 lasers use a gas mixture of carbon dioxide to generate the laser beam. These lasers are excellent for cutting thicker non-metal materials like wood, plastics, and acrylic. However, CO2 lasers tend to be less efficient for metal cutting, especially when cutting thicker materials.

While they can still cut through metals like mild steel, aluminum, and copper, their cutting speed and precision typically don't match that of fiber lasers. CO2 lasers² also consume more energy, leading to higher operating costs.

Fiber Laser Cutters

Fiber lasers, on the other hand, are more efficient and suitable for cutting metal. These lasers use fiber-optic technology to generate the beam, which allows for higher precision, speed, and energy efficiency. Fiber lasers are the preferred option for metal cutting because of their ability to handle a wide variety of metals and thicknesses with greater efficiency.

When choosing between a CO2 laser and a fiber laser, the power of the laser is a key factor. Lower-powered fiber lasers (1kW-3kW) are ideal for cutting thinner materials (up to 10mm thickness). However, for heavier-duty metal cutting (up to 30mm thickness), you’ll need higher-powered fiber lasers (12kW and above).

Laser Type	Material Suitability	Power Range	Cutting Speed	Efficiency
CO2 Laser	Suitable for non-metal and thin metal	1-6kW	Moderate	Lower energy efficiency
Fiber Laser	Best for metal (steel, aluminum, copper)	1-20kW	High	High energy efficiency

Choosing the right laser machine involves more than just the laser type. The laser power³ and the specific metals you need to cut play a crucial role in making the best choice.
