What materials can an abrasive waterjet cut? What is the maximum thickness?

An abrasive waterjet is one of the most versatile cutting technologies available today. It can cut virtually any material, regardless of hardness, density, reflectivity, or thermal sensitivity. Unlike laser or plasma cutting, waterjet cutting does not rely on thermal energy, so it is not limited by material properties such as reflectivity or thermal conductivity. This makes it suitable for metals, non-metals, composites, ceramics, glass, stone, rubber, plastics, and even food products.

For metals, the abrasive waterjet cuts all common engineering alloys including stainless steel, aluminum, titanium, brass, copper, Inconel, Hastelloy, tool steels, and armor-grade steels. With a typical ultra-high pressure pump operating at 6,000 Bar (87,000 PSI), the maximum cutting thickness for steel reaches 300mm, while aluminum can be cut up to 400mm. Titanium, widely used in aerospace and medical applications, can be cut up to 250mm thick. Copper and brass can be cut up to 250mm to 300mm. In practical production environments, stainless steel up to 200mm is commonly cut with excellent edge quality and zero heat-affected zone.

For composites, the waterjet is the preferred cutting method because it preserves the integrity of layered materials. Carbon fiber reinforced polymers (CFRP), glass fiber reinforced polymers (GFRP), Kevlar, and honeycomb structures are all cut without delamination, fraying, or thermal damage – problems that are common with mechanical or thermal cutting methods. The maximum thickness for composites generally ranges from 100mm to 200mm, depending on the weave structure and resin system.

For non-metallic materials, the 5-axis waterjet excels in cutting stone (granite, marble, slate, quartz) up to 300mm thick, glass up to 250mm thick, ceramics up to 200mm thick, and dense rubber or plastics up to 400mm thick. In aerospace, waterjets cut titanium and CFRP stacks in a single pass, eliminating the need for multiple tools. In automotive, they cut interior panels, acoustic foams, and structural composites. In architecture, they cut intricate stone patterns and tile mosaics. In defense, they cut armor plate and composite armor systems.

One of the key advantages of waterjet cutting is that the "cold cutting" process preserves the material's original properties. There is no heat-affected zone, no metallurgical change, no micro-cracking, and no delamination. Materials that are heat-sensitive, such as titanium alloys and carbon composites, are cut without compromising their mechanical properties. The cut edge is smooth with surface roughness of Ra 1.6 to 3.2 microns, ready for welding, coating, or bonding without secondary cleaning.
