When a fabrication program calls for a challenging grade like hardened tool steel, titanium, copper, or brass, the real question is whether the cutting method can handle that specific grade without damaging it. Hydro-Lazer, Inc. provides metal cutting services from Freeport, Pennsylvania, using abrasive waterjet technology. The process cuts carbon steel, stainless steel, hardened tool steel, aluminum, titanium, copper, and brass with clean edges, no burrs, and no burn marks.
Can Waterjet Cut Hardened Tool Steel?
Hardened tool steel is one of the most challenging grades in precision metal fabrication. Its extreme hardness makes it valuable for tooling applications, but it also makes it difficult to cut cleanly with conventional methods.
- Compatibility: Hardened tool steel is a fully documented compatible material for Hydro-Lazer’s metal cutting services.
- What Happens with Conventional Methods? EDM is slow and limited in geometry. Plasma and laser cutting introduce heat that can crack hardened steel or alter its temper at the cut edge. That thermal stress alters the material’s metallurgical state, compromising the hardness properties for which the grade was specified.
- How does a waterjet work on This Grade? Abrasive waterjet cuts through hardened tool steel at high velocity with no heat generated. The temper and hardness of the material are fully preserved from the first cut to the last. No work hardening occurs, and the metal grain structure stays unchanged throughout the cutting process.
- The Output: Components come out dimensionally accurate, with their metallurgical properties fully intact, and with clean cuts, no burrs, burn marks, or cracks, ready for tooling, dies, and precision mechanical assemblies.
Does Waterjet Work on Titanium?
Titanium is the material of choice for applications where strength-to-weight ratio and corrosion resistance are non-negotiable. It is also the grade most vulnerable to thermal cutting damage.
- Compatibility: Titanium is fully documented as a compatible material for Hydro-Lazer’s metal-cutting services.
- What Happens with Conventional Methods? Titanium is highly reactive at elevated temperatures. Heat from laser or plasma cutting causes oxidation and surface contamination at the cut edge. In aerospace and power-generation components, oxidation compromises corrosion resistance and structural integrity at cut edges.
- How does a waterjet work on This Grade? Abrasive waterjet cutting is a cold process. No heat is generated at any point during the cut. Thermal reactivity is a non-factor in this process. No heat-affected zones form, no oxidation occurs, and no surface contamination is introduced.
- The Output: Clean, burr-free cuts on titanium with no burn marks, no cracks, and no change in grain structure. Corrosion resistance and structural integrity remain exactly as specified, which is essential for aerospace structural components, mining equipment, and power generation assemblies.
Can Waterjet Cut Copper Without Heat Distortion?
Copper presents a distinct cutting challenge. Its high thermal and electrical conductivity means heat introduced during cutting distributes rapidly through the material, creating heat-affected zones across a wider area.
- Compatibility: Copper is fully documented as a compatible material for Hydro-Lazer’s metal-cutting services.
- What Happens with Conventional Methods? Plasma and laser cutting introduce heat that conducts rapidly through copper’s structure. Wider heat-affected zone margins, discoloration, and potential dimensional distortion spread across the part. EDM is slow and geometrically limited on complex copper components.
- How does a waterjet work on This Grade? No heat is generated during waterjet cutting. Copper’s conductivity is irrelevant to a cold cutting process. The abrasive water stream cleanly cuts through copper, regardless of its thermal properties.
- The Output: Clean cuts with no burn marks, no burrs, and no distortion. Copper components arrive with consistent edge geometry and no heat-induced dimensional variation, suitable for electrical assemblies, power generation components, and precision industrial fabrication.
Does Waterjet Handle Brass for Decorative and Precision Applications?
Brass is specified across decorative fabrication, mechanical components, and precision industrial parts. It is fully documented and compatible with waterjet cutting at Hydro-Lazer.
- Compatibility: Brass is fully documented as a compatible material for Hydro-Lazer’s metal-cutting services.
- What Happens with Conventional Methods? Brass’s zinc content makes it susceptible to stress-corrosion cracking under mechanical cutting forces. Thermal cutting can alter the alloy composition at the cut edge. Both affect surface finish quality in decorative applications and dimensional accuracy in precision parts.
- How does a waterjet work on This Grade? No mechanical contact force or heat is applied. Brass is cut with the abrasive water stream without introducing stress or thermal alteration to the alloy. The zinc content stays undisturbed, and the edge comes out clean.
- The Output: Burr-free cuts with clean edges, suitable for decorative sign fabrication, architectural elements, precision mechanical components, and industrial brass assemblies.
What Makes Waterjet the Right Choice for These Metal Grades?
Hardened tool steel, titanium, copper, and brass each present different cutting challenges. Waterjet eliminates all those failure modes through a single underlying mechanism.
No Heat Generated
This single property eliminates heat-affected zones across all four grades, thermal distortion in copper, oxidation in titanium, temper alteration in hardened tool steel, and alloy composition changes in brass.
No Direct Mechanical Contact
The waterjet stream exerts no contact force, as with a blade or grinding wheel. Work hardening, stress corrosion cracking in brass, and mechanical surface damage are all eliminated.
Additional Process Advantages
Waterjet metal cutting services are 5 to 10 times faster. The process cuts thicker metals that are otherwise difficult to cut with plasma. Minimal material wastage makes it economically viable for both prototype quantities and large contract runs. Clean cuts with no burrs, burn marks, or cracks are consistent across all documented metal grades.

Frequently Asked Questions
Can waterjet cutting handle hardened tool steel without cracking or altering the temper?
Abrasive waterjet cutting hardened tool steel generates no heat, so the temper is fully preserved throughout the cut. No cracking, no grain structure change, and no hardness alteration occur. The workpiece exits the cutting program with its specified metallurgical properties intact.
Why is waterjet preferred over laser or plasma for cutting titanium?
Titanium is highly reactive at elevated temperatures, and laser and plasma cutting introduce enough heat to cause oxidation and surface contamination at the cut edge. Waterjet is a cold process that generates no heat, eliminating oxidation and heat-affected zones. Titanium’s material properties are fully preserved.
Does waterjet cutting affect copper’s electrical conductivity?
Waterjet cutting generates no heat, so copper’s thermal and electrical properties are unaffected by the cutting process. The cold, abrasive stream cuts copper cleanly without introducing heat-affected zones or dimensional distortion, as plasma and laser processes do in high-conductivity metals.
Can a waterjet cut brass without stress corrosion cracking?
Brass is susceptible to stress-corrosion cracking under mechanical cutting forces, whereas waterjet does not make direct mechanical contact with the workpiece surface. Combined with the absence of heat, the waterjet produces clean, burr-free brass cuts without altering the alloy composition or introducing stress into the material.
How does waterjet compare to EDM for cutting titanium or hardened steel?
Waterjet cutting is 5 to 10 times faster and is not geometrically limited like EDM is on complex parts. EDM is also slow on thicker stock, whereas waterjet can handle thicker metals that are otherwise difficult to process with conventional methods.
