CuAlFeMnNi
Trumet's first developed high-entropy alloy, combining copper, aluminium, iron, manganese and nickel.
Development pathway
How CuAlFeMnNi moved from a computational candidate to a characterized material.
Screening
Candidate compositions across the five-element system were evaluated against multiple design criteria on Trumet's platform.
Fabrication
Selected compositions were produced as physical samples.
Characterization
Samples were analysed for microstructure and properties and compared against predicted behaviour.
Application development
Ongoing work toward use in target applications with industry partners.
Properties
Detailed data is shared with qualified partners under NDA.
