Why and When to Choose Waterjet Cutting for Aluminium Machining

waterjet cutting aluminium

When it comes to cutting and shaping aluminium profiles, most manufacturers turn to saws, routers, or CNC machines by default. But sometimes, those traditional methods hit a wall—literally. That’s when waterjet cutting becomes not just an option, but the best solution.

At ALUCAD, we’ve invested in waterjet cutting technology for precisely this reason. While it’s not the most common method, it’s one of the most versatile and effective for certain use cases—especially when precision, thickness, or complex geometry come into play.

What is waterjet cutting?

Waterjet cutting uses a high-pressure stream of water, often combined with an abrasive, to slice through materials with surgical precision. It’s a cold process—no heat, no burning, no distortion—which makes it ideal for aluminium, a metal known for warping or hardening under high temperatures.

Unlike lasers or saws, waterjet cutting works by erosion. It gradually removes material in a highly controlled manner, producing clean edges, no burrs, and virtually zero thermal stress.

When should you use waterjet cutting?

Here are the situations where waterjet cutting is the superior choice for aluminium profile machining:

• Thick material: Cutting through solid aluminium blocks or thick profiles without warping or melting the edges.

• Complex or curved cuts: Creating intricate internal shapes, rounded corners, or custom openings that standard machines can’t handle.

• No thermal impact: Essential for parts where heat can alter material properties or dimensional accuracy.

• Unreachable sections: Machining areas that saw blades or end mills physically can’t access.

• Aesthetic features: Designing architectural or decorative elements where edge quality and detail matter.

In short: if your part can’t be done conventionally without compromise, waterjet is your answer.

ALUCAD’s approach to smart cutting

We don’t push waterjet cutting for everything—just when it’s the right tool. Our team evaluates your profile’s geometry, thickness, and function to determine the most cost-effective and technically appropriate machining process.

And if that turns out to be waterjet cutting, we’ve got the equipment and expertise to do it right. Clean, consistent results, protected surfaces, and zero compromise on function or finish. Contact us today.
