What Materials Can a Fiber Laser Cut?

Fiber laser cutting machines are renowned for their precision, speed, and versatility in modern manufacturing. But what exactly can they cut? This guide dives deep into the wide range of compatible materials, helping you understand the capabilities of this powerful technology.

Metals: The Primary Domain

Fiber lasers excel at cutting reflective metals with exceptional quality. Key materials include:

Mild Steel: Up to 30mm thick, it cuts cleanly with minimal dross.

Stainless Steel: Ideal for food-grade or medical parts, offering oxidation-free edges.

Aluminum: While reflective, modern fiber lasers can cut alloys up to 25mm thick.

Copper and Brass: Requires specific laser parameters but yields precise cuts for electrical components.

Beyond Metals: Other Compatible Materials

While metals are the forte, fiber lasers can also process:

Plastics: Certain types like acrylic and polycarbonate can be cut, though CO2 lasers are often preferred for organics.

Composites: Used in aerospace for trimming carbon fiber or fiberglass panels.

It’s crucial to consult your machine manual, as cutting non-metals may require specific settings and ventilation.

Key Factors Influencing Cut Quality

Material cutability depends on laser power, assist gas (like nitrogen or oxygen), and focal point adjustment. A 6kW laser will handle thicker steel than a 1kW model.

Frequently Asked Questions (FAQ)

Can a fiber laser cut wood or fabric?

Typically, no. These materials are best suited for CO2 lasers due to their wavelength absorption properties.

What about reflective materials?

Modern fiber lasers have systems to handle reflection, making them superior for copper and brass compared to older laser types.

How precise is the cut?

Extremely. Fiber lasers can achieve kerf widths as small as 0.1mm, perfect for intricate designs.
