Gränges Powder Metallurgy has developed two specialized aluminium-scandium alloys for use in Laser Beam Powder Bed Fusion. These materials are engineered to perform in high-temperature settings and hydrogen-rich environments.
Why it matters
The alloys were designed to bypass material supply constraints and offer superior performance for critical applications that require durability in extreme heat or hydrogen exposure. These advancements aim to expand the capabilities of additive manufacturing in specialized industrial sectors.
The Al-Mg-Sc alloy is optimized for operation within a hydrogen-rich environment at temperatures ranging from 100-250°C. Researchers at IRT M2P are currently using atomisation trials to refine alloy chemistry, while PINT establishes manufacturing parameters.
The players
Gränges Powder Metallurgy
A company based in Saint-Avold, France, that specializes in the production of high-performance metal powders for additive manufacturing.
IRT M2P
A research institute located in Metz, France, that works on industrial innovation and metallurgical trial processes.
PINT
A collaborative entity based in Metz that focuses on developing specialized process parameters for additive manufacturing technologies.
The details
The development resulted from the three-year AluScaL project, which sought to improve additive manufacturing performance using scandium-based formulations. Current efforts are focused on completing material testing and securing patent protections before the production of demonstrator components.
Timeline
The AluScaL project concluded in 2025 after a three-year duration.
Material testing for the Al-Si-Sc alloy is expected to conclude in Q4 2026.
Initial trial results for the Al-Mg-Sc alloy are expected by Q4 2026.
First demonstrator components are anticipated for release in 2027.
Deeper Dive
This development follows the research milestones established by the AluScaL project. The move represents a shift toward specialized, high-performance alloy design as a solution to supply chain constraints and evolving additive manufacturing requirements.
These alloys could eventually lead to stronger, more heat-resistant components for hydrogen infrastructure and aerospace industries. Commercial availability depends on the successful completion of qualification trials scheduled for 2027.
The takeaway
These scandium-enhanced alloys offer a potential solution for industries facing extreme thermal and chemical stressors. Researchers expect to transition these materials from the lab to real-world demonstrator components within the next few years.
