If you’ve ever asked what materials can be laser cut, you’re in good company. It’s one of the most common questions from engineers, fabricators, architects, and first-time buyers across Australia. The short answer is: a wide range. The more useful answer covers which materials cut well, which require specific equipment, and what determines the quality of the finished result.
Laser cutting materials span everything from industrial-grade steel plate and stainless steel sheet through to aluminium alloys, specialty metals, and non-metals like acrylic and MDF. But not all laser cutters handle all materials equally. The type of laser, the power level, the assist gas selection, and operator expertise all play a direct role in cut quality and cost.
This laser cutting guide focuses on the materials processed at Absolute Laser Cutting on the Gold Coast, primarily metals using industrial CNC fibre laser technology, with a broader overview of non-metals for context. Whether you’re sourcing precision laser cutting services for the first time or comparing material options for a new project, this is the complete answer.
What Materials Can Be Laser Cut: Metals vs Non-Metals
Laser cutting materials fall into two broad categories, each requiring a different laser technology.
Category | Laser Type | Common Materials |
| Metals | Fibre Laser | Mild steel, stainless steel, aluminium, galvanised steel, Zincalume, Corten, brass, copper |
| Non-Metals | CO2 Laser | Acrylic, MDF, plywood, timber, leather, rubber, foam |
Fibre laser is the current industry standard for metal laser cutting services. It produces a shorter wavelength beam that is efficiently absorbed by metals, delivering fast cutting speeds and excellent edge quality. CO2 laser operates at a wavelength better suited to non-metallic materials and is not the right technology for reflective metals like aluminium.
At Absolute Laser Cutting, we specialise in CNC laser cutting for metals using industrial fibre laser equipment, serving fabrication, manufacturing, construction, agriculture, architecture, and engineering clients across the Gold Coast, Brisbane, and Queensland-wide.
Mild Steel Laser Cutting
Mild steel is the most widely used material in industrial laser cutting, and for good reason. It’s strong, weldable, cost-effective, and available in a wide thickness range that suits everything from thin sheet metalwork to heavy structural plate.
Grades We Cut
Grade | Characteristics | Common Use |
| MS250 | Standard structural mild steel | General fabrication, brackets, panels |
| MS350 | Higher yield strength | Structural components, load-bearing parts |
| AR400 | Abrasion-resistant wear plate | Mining equipment, chutes, hoppers |
| Hardox | Premium wear and impact resistance | Heavy plant, earthmoving, conveyor systems |
Thickness Range for Mild Steel
Thickness | Typical Applications |
| 0.5mm to 2mm | Sheet metal enclosures, guards, thin brackets, decorative panels |
| 3mm to 6mm | Structural brackets, gussets, mounting plates, screen panels |
| 8mm to 12mm | Heavy brackets, machinery bases, wear plates, load-bearing components |
| 16mm to 20mm | Structural plate, counterweights, heavy fabrication components |
Edge Quality: Fibre laser cutting on mild steel produces a clean, consistent, weld-ready edge. Oxygen assist produces a slightly oxidised edge suited to welded fabrication. Nitrogen assist produces a cleaner, brighter edge preferred for powder-coated or decorative finishes.
Best for: Fabrication, structural components, manufacturing parts, agricultural equipment, machinery frames, architectural screens, and general engineering.
Stainless Steel Laser Cutting
Stainless steel laser cutting is in constant demand across industries where corrosion resistance, hygiene, and surface finish are essential. Food processing, hospitality, marine, medical, architectural, and coastal construction applications all rely on stainless for its performance in demanding environments.
Grades We Cut
- 304 Stainless: The most widely used grade. Suited to indoor and general-purpose applications where moderate corrosion resistance is sufficient.
- 316 Stainless: Contains molybdenum for significantly higher resistance to chloride corrosion. The correct choice for marine environments, coastal architecture, food-grade processing, and chemical applications.
Thickness Range for Stainless Steel
| Thickness | Typical Applications |
| 0.5mm to 2mm | Food equipment panels, cosmetic covers, fine architectural elements |
| 3mm to 6mm | Kitchen equipment, marine fittings, structural brackets |
| 8mm to 12mm | Heavy marine hardware, industrial processing components, structural architectural elements |
Edge Quality: Nitrogen assist gas produces a smooth, bright, oxide-free edge on stainless steel. This is important for hygiene-critical applications and visible architectural finishes, and typically eliminates the need for secondary polishing on standard stainless jobs.
Best for: Food and beverage equipment, marine hardware, architectural facades, dairy and agricultural processing, medical components, coastal construction, and premium interior design.
Aluminium Laser Cutting
Aluminium is one of the most versatile laser cut metal materials, offering a lightweight, corrosion-resistant option across transport, marine, architecture, electronics, signage, and precision engineering applications.
Important: Aluminium requires fibre laser technology, not CO2. Aluminium reflects CO2 laser wavelengths, making CO2 cutting inefficient and potentially damaging to the machine. Fibre laser absorbs into aluminium effectively, producing clean cuts and controlled edge quality.
Alloys We Cut
- 5052 Aluminium: Marine-grade alloy with excellent corrosion resistance and formability. Suited to marine hardware, automotive panels, architectural elements, and enclosures.
- 6061 Aluminium: Structural alloy with higher strength and good machinability. Suited to engineering components, machinery parts, and structural applications where strength-to-weight ratio is the priority.
Thickness Range for Aluminium
Thickness | Typical Applications |
| 0.5mm to 2mm | Signage blanks, decorative panels, lightweight enclosures |
| 3mm to 6mm | Architectural screens, structural brackets, marine panels |
| 8mm to 10mm | Engineering components, transport parts, structural elements |
Best for: Marine hardware, transport and automotive components, architectural and interior design panels, electronics enclosures, signage, and precision engineering.
Specialty Metals: Galvanised Steel, Zincalume, and Corten
Beyond the three primary metals, several specialty materials are regularly requested by Australian fabricators and builders.
Galvanised Steel and Zincalume
Both Galvanised steel and Zincalume are mild steel products with a protective zinc or zinc-aluminium coating applied for corrosion resistance. They are commonly used in agricultural buildings, structural framing, roofing components, and outdoor fabrication.
- Galvanised steel: Cut up to 4mm using nitrogen or air assist. The zinc coating produces fumes during cutting, so proper extraction is essential.
- Zincalume: Similar cutting parameters to galvanised. Used frequently in commercial building and agricultural applications.
Corten Steel (Weathering Steel)
Corten is a high-strength, low-alloy steel that forms a stable rust-like patina on the surface when exposed to weather, eliminating the need for paint or coating. It is a popular choice for architectural features, landscaping, garden edging, signage, and public art installations.
Corten cuts in a similar way to standard mild steel on fibre laser equipment and produces an excellent edge for decorative applications.
Brass and Copper
Brass and copper can be laser cut but are considered specialist materials due to their high reflectivity. They require specific machine settings and additional laser power. Cut quality is achievable but costs are higher than standard metals. Contact us before specifying brass or copper for a laser cutting project to confirm feasibility and pricing.
What Materials Cannot Be Laser Cut: Know the Limits
Understanding what materials can be laser cut also means knowing what to avoid. Certain materials should never be processed through a laser cutter.
| Material | Reason to Avoid |
| PVC and vinyl | Releases hydrogen chloride gas, which is toxic and damages the machine |
| Polycarbonate (PC) | Burns rather than cuts cleanly, releases toxic fumes |
| Fibreglass and composites | Releases carcinogenic glass fibres and resin fumes |
| Chromium-coated metals | Releases toxic chromium fumes during cutting |
| ABS plastic | Releases toxic styrene fumes and produces a poor cut edge |
| Painted or heavily coated steel | Surface contaminants affect cut quality and release fumes |
If you’re unsure whether your material is laser cuttable, send through a sample specification and our team will confirm before quoting.
What Affects Laser Cutting Quality on Different Materials
Knowing what materials can be laser cut is only half the picture. Cut quality depends on several variables that work together.
- Laser Type Fibre laser for metals. CO2 for non-metals. Using the wrong laser type for a material produces poor results and risks machine damage.
- Laser Power Higher power enables cutting of thicker materials and faster speeds on thinner gauges. Our industrial fibre laser handles the full range of thicknesses listed in this guide without compromise.
- Assist Gas Selection
| Gas | Used For | Edge Result |
| Oxygen | Mild steel | Slight oxidation, suited to welded fabrication |
| Nitrogen | Stainless steel, aluminium, decorative mild steel | Bright, clean, oxide-free edge |
| Compressed Air | Lower-cost applications in mild steel and aluminium | Acceptable for non-cosmetic applications |
- Material Surface Condition Clean, scale-free, flat material produces the best results. Mill scale, heavy rust, surface contamination, and paint all affect how the laser interacts with the material, potentially causing inconsistent cutting and edge defects.
- Part Geometry Tight internal corners, very small holes, and thin webs between features all influence cut quality. Our CAD team reviews files before cutting to identify any geometry that could affect the result and flag it before production begins.
How to Choose the Right Laser Cutting Material for Your Project
Not sure which material suits your project? Work through these four questions and the right choice becomes clear.
What environment will the part live in?
Outdoor and coastal environments need corrosion-resistant materials such as 316 stainless, aluminium, or galvanised steel. Indoor structural work can use mild steel with a protective coating. Food-contact and hygiene-critical environments need 304 or 316 stainless. Marine applications almost always call for 316 stainless or marine-grade 5052 aluminium.
What mechanical properties are required?
High-strength structural requirements point toward mild steel. Weight-critical applications favour aluminium. Wear-resistant applications may need AR400 or Hardox. Fatigue resistance in marine environments points toward 5052 aluminium or 316 stainless.
What surface finish is needed?
If the part will be powder coated, mild steel is typically the most cost-effective substrate. If the natural metal surface will remain visible, such as brushed stainless, anodised aluminium, or raw Corten, material and finish need to be considered together. For architectural screens and decorative panels where the cut edge is part of the visual outcome, nitrogen-cut stainless or aluminium delivers the cleanest result.
What is the budget?
Mild steel is the most cost-effective laser cut metal material per kilogram. Aluminium and stainless cost more per kilogram, and that flows through to the cut price. However, for exposed applications where corrosion protection coatings would otherwise be required, the material premium on stainless or aluminium can offset the higher raw material cost over the life of the part.
Why Australian Industries Choose Precision Laser Cutting
The shift toward CNC laser cutting services across Australian industry reflects genuine performance advantages over alternatives like plasma, waterjet, and mechanical punching.
- Tighter tolerances: Precision laser cutting holds ±0.1mm, a standard plasma cannot consistently achieve and mechanical processes struggle to match at production speeds.
- Cleaner edges: Fibre laser produces a narrow kerf with smooth, consistent edges, reducing or eliminating secondary grinding, deburring, and edge dressing.
- Greater design flexibility: Complex geometries, intricate patterns, tight radii, and internal cutouts that would be slow or impossible with mechanical cutting are standard laser cutting output.
- No tooling costs: Unlike stamping and punching, laser cutting requires no physical tooling, making it the economical choice for both small custom runs and high-volume production.
- Fast turnaround: Industrial laser cutting is fast, particularly on thin to medium gauge materials, with CNC nesting software that maximises sheet utilisation and keeps cost per part low.
