Laser metal cutting is a widely used manufacturing process that offers precision and efficiency across various industries. This technology is capable of cutting through different types of metals with high accuracy, making it an ideal choice for both small-scale and large-scale projects. In this blog, we will explore the most common metals used in laser cutting, including mild steel, stainless steel, aluminium, galvanised mild steel, Zintec, copper, and brass.

Stainless Steel

Stainless steel is known for its corrosion resistance and attractive finish, making it popular in industries like food processing, medical devices, and architectural applications. Laser cutting provides a clean and precise cut on stainless steel, preserving its aesthetic qualities and structural integrity. This metal’s ability to withstand high temperatures without warping makes it suitable for laser cutting, which involves intense heat.

Aluminium

Aluminium is lightweight, durable, and resistant to corrosion, which makes it a preferred material in industries such as aerospace, automotive, and electronics. Laser cutting is highly effective for aluminium, especially in thin sheets, where it delivers precise cuts with minimal material wastage. The reflective nature of aluminium requires specialised laser settings, but modern laser cutting machines are well-equipped to handle this challenge efficiently.

Galvanised Mild Steel

Galvanised mild steel has a protective zinc coating that provides additional resistance to corrosion. This makes it suitable for outdoor applications, such as fencing, roofing, and structural components. Laser cutting can easily slice through galvanised mild steel, although care must be taken to manage the fumes generated by the zinc coating during the process.

Zintec

Zintec is a form of mild steel coated with a thin layer of zinc, offering corrosion resistance and improved adhesion for paints and coatings. It is often used in the automotive and construction industries. Laser cutting Zintec is straightforward, producing precise cuts that maintain the integrity of the zinc layer, which is critical for the metal’s protective qualities.

Copper and Brass

Copper and brass are used in decorative, electrical, and plumbing applications due to their conductivity and appealing appearance. Laser cutting is effective for these metals, although their reflective surfaces and thermal conductivity present unique challenges. Advanced laser systems equipped with specialised settings can achieve high-quality cuts on copper and brass, making them suitable for intricate designs and detailed components.

Laser metal cutting offers unmatched precision and efficiency for a wide range of metals. Whether you are working with materials that require corrosion resistance, lightweight properties, or electrical conductivity, laser cutting provides a versatile solution that meets diverse industrial needs. By understanding the capabilities and applications of laser metal cutting, businesses can make informed decisions and achieve superior results in their projects.
