Trumet Alloys Technologies uses a computer-implemented, multi-criteria design platform to find high-entropy alloys that meet your requirements, then fabricates and characterizes them to prove it.

What we do
Most engineering alloys were developed decades ago around one or two base metals. Trumet works in the much larger space of high-entropy alloys, where five or more elements share the lattice, and narrows it down with software before anything is melted.
Design
We translate your mechanical, thermal, weight and manufacturing requirements into design criteria and search candidate compositions against all of them at once.
Develop
Promising candidates are fabricated and characterized so their properties are measured, not just predicted.
Deploy
Validated materials move toward use in aerospace, defense, marine and additive manufacturing applications, with partners who need them.
How it works
From a list of requirements to a validated material, in four stages.
Define requirements
Strength, density, corrosion resistance, operating temperature, cost and printability are captured as measurable targets.
Explore candidates
The platform generates and evaluates candidate compositions across the full multi-element design space.
Rank the trade-offs
Candidates are scored against every criterion together, so gains in one property aren't bought with hidden losses in another.
Validate
The strongest candidates are fabricated and characterized in the lab before they're recommended for use.
CuAlFeMnNi, our first alloy
A five-element high-entropy alloy taken from computational screening through fabrication and characterization.
It uses the same elements found in marine-grade nickel-aluminium bronzes, explored across a far wider range of proportions than conventional alloy design allows.
Industries served
Where demanding environments make off-the-shelf alloys a compromise.
Aerospace
Lighter components that hold strength under heat, load and vibration.
Defense
Materials matched to mission requirements and sovereign supply needs.
Marine
Resistance to seawater corrosion, cavitation and biofouling.
Additive manufacturing
Alloys screened for printability from the start, not adapted afterwards.

Frequently asked questions
Something else on your mind? Ask us directly.
What is a high-entropy alloy?
An alloy built from five or more principal elements in roughly comparable amounts, rather than one base metal with small additions. This opens up combinations of properties that conventional alloys can't reach.
Can Trumet design an alloy for my specific application?
Yes. That's the core of what we do. Start with a consultation and we'll work through your requirements, constraints and timeline.
Do you only work with CuAlFeMnNi?
No. CuAlFeMnNi is our first developed alloy, but the platform can explore other element systems when an application calls for it.
Are your alloys suitable for 3D printing?
Manufacturability, including for additive manufacturing, is one of the criteria we screen for from the start rather than an afterthought.
How do you validate a new alloy?
Candidates are fabricated and characterized to measure their structure and properties against the original targets before we recommend them.
How do research collaborations work?
We work with universities, labs and industry on joint projects and funded programs. Use the contact form and choose "Research collaboration".
Have a material problem that standard alloys don't solve?
Tell us what the part needs to do. We'll tell you how we'd approach it.
