Introduction

Waterjet cutting is transforming fabrication and manufacturing thanks to its ability to cut almost any material with extreme accuracy and no heat damage. Unlike traditional methods like sawing or laser cutting, which rely on friction or thermal force, waterjet cutting uses a high-pressure stream of water (often with abrasive particles) to produce smooth, clean edges without distortion.

At Metal & Wood Products, we specialize in precision waterjet cutting services for industries ranging from architecture to aerospace. Selecting the right materials can make all the difference when it comes to maximizing results, minimizing waste, and improving overall efficiency.

Here’s our guide to the top 5 materials best suited for waterjet cutting, why they work so well, and how they support high-performance results on a wide variety of projects.

1. Metals – Precision Cutting Without Heat Damage

Why Metals Excel with Waterjet Cutting

• No Heat-Affected Zones (HAZ) – Waterjets cut without heat, preserving the material’s strength and finish.
• Thick Material Capability – Easily cuts metals up to 12 inches thick.
• Smooth Edge Finish – Reduces the need for secondary finishing or grinding.

Best Metals for Waterjet Applications

• Stainless Steel – Excellent for sanitary, food-safe, and corrosion-resistant applications.
• Aluminum – Lightweight and strong, ideal for aerospace, automotive, and marine use.
• Titanium – Common in high-performance environments like aircraft and medical components.
• Brass & Copper – Great for decorative and electrical projects.
• Mild Steel – A staple in our shop and one of the most commonly cut materials at Metal & Wood Products. Its availability, strength, and affordability make it ideal for countless industrial and custom applications.

2. Stone & Tile – Intricate Designs with No Chipping

Advantages of Waterjet Cutting for Stone

• High Precision – Ideal for intricate inlays, mosaics, and custom shapes.
• No Chipping or Cracking – Cold cutting avoids structural damage.
• Complex Designs – Perfect for custom countertops, backsplashes, and flooring.

Popular Stone Materials for Waterjet Cutting

• Granite – Durable and stylish for kitchens and vanities.
• Marble – Great for sculptures and decorative accents.
• Porcelain & Ceramic – Popular in tile work and interior finishes.

3. Glass – Flawless Cutting for Delicate Materials

Why Waterjet is Ideal for Glass

• No Micro-Fractures – Leaves a smooth, safe edge.
• Creative Flexibility – Enables complex curves and detailed designs.
• Minimal Finishing Required – Clean edges straight from the cutter.

Important Note: Not all glass is suitable for waterjet cutting. Waterjets can effectively cut non-tempered glass and laminated safety glass. However, tempered glass cannot be cut using waterjets—it will shatter due to its internal tension.

Common Glass Applications

• Stained Glass and Custom Art Panels
• Architectural Glass Panels (non-tempered)
• Laminated Safety Glass for Commercial Use

4. Composites – Clean Cuts Without Delamination

Composite materials are known for strength and lightweight properties, but they’re often tricky to cut cleanly. Waterjet cutting is an ideal solution.

Benefits of Waterjet Cutting for Composites

• No Fraying or Delamination – Clean edges without tool wear.
• Preserves Structural Integrity – No damage from friction or heat.
• Precision for Multi-Layer Builds – Perfect for complex assemblies.

Top Composite Materials

• Carbon Fiber
• Fiberglass
• Kevlar

5. Rubber & Foam – Soft Materials, Precision Results

Flexible materials like rubber and foam require clean cuts without distortion. Waterjets deliver just that.

Why Waterjet Cutting Works for Rubber & Foam

• No Melting or Warping – Maintains original shape and structure.
• Clean, Sealed Edges – Prevents fraying and unravelling.
• Ideal for Seals and Packaging – Common in industrial gaskets, insulation, and custom cases.

FAQs About Waterjet Cutting Materials

1. What is the maximum thickness a waterjet can cut?

Waterjet cutters can handle materials up to 12 inches thick, depending on density and composition. They remain precise even with thicker stock.

2. Can waterjet cutting handle brittle materials like glass?

Yes—for non-tempered and laminated glass, waterjet is ideal. It avoids microfractures and creates smooth edges. However, tempered glass is not compatible.

3. Is waterjet cutting cost-effective?

While the upfront machine cost may be higher, waterjet cutting reduces waste, requires less finishing, and offers unmatched versatility—often saving time and money in the long run.

4. Does waterjet cutting work on layered or composite materials?

Absolutely. Composites like carbon fiber and fiberglass can be stacked and cut cleanly, making waterjet ideal for aerospace and automotive work.

5. How precise is waterjet cutting?

Waterjet cutting offers tight tolerances—up to ±0.005 inches—perfect for detailed metalwork and precision components.

Conclusion

Choosing the best materials for waterjet cutting helps ensure clean results, minimal waste, and efficient production. Whether you’re cutting stainless steel, shaping stone, or detailing non-tempered glass, waterjet technology offers unmatched precision across materials.
