Scandium Canada updates on its proprietary Aluminum-Scandium Alloys
Scandium Canada updates on its proprietary Aluminum-Scandium Alloys
Montreal, QC, September 25, 2025 — Scandium Canada Ltd. is pleased to announce that
new data on the properties of its modified AA535 and AA7075 alloys confirm an
economically viable technological advancement in the field of aluminum -scandium (Al-Sc)
alloys explicitly developed for additive manufacturing applications. The current results are
focused on the properties of samples printed through the laser powder -bed fusion (L-PBF)
process. The company’s latest results substantiate that Scandium Canada’s alloys offer a
practical solution to one of the most persistent challenges in metal 3D printing: eliminati ng
cracking in high-strength aluminum alloys, which paves the way for a new era of lightweight,
high-performance, and cost -effective components across multiple industries. See press
release : Scandium Canada updates on aluminum -scandium 3D powders research and
development. It should be noted that Scandium Canada has established a division within
the company, Scandium +, dedicated explicitly to ramp up commercialization efforts for
these two Al-Sc powders and the development of other Al -Sc alloys, to engage in dialogue
with end-users. Press release : Scandium Canada Ltd. makes changes to its management
team and corporate structure.
Scandium+'s main objectives are to :
• Deploy scandium in markets with the highest needs.
• Commercialization of patent-pending Al-Sc alloys with potential in multiple sectors
(AA7075/Sc/Zr & AA535/Sc/Zr/Ce).
• Focus on value-added Scandium alloys.
The main attributes of Scandium Canada’s Al-Sc powders include:
• Reduced Scandium Content: The technology enables significant reductions in the
amount of scandium required, directly addressing cost and resource sustainability.
The alloys maintain the grain-refining effect necessary to eliminate hot cracking
during L-PBF processing, making high -quality production possible at lower material
expense.
• Broad Processing Window: The newly developed aluminum -scandium-zirconium
alloys exhibit printability across a wide range of laser power and scanning speed
parameters. Testing has confirmed relative densities above 99% under optimal
conditions, a key measure for component integrity and reliability.
• Suitable Mechanical Properties: Mechanical testing shows ultimate tensile
strengths (UTS) ranging from approximately 330 to 380 MPa in the as-built state. With
heat treatment, these alloys achieve UTS increases of 17–25%.
• Minimized Defect Density: The proprietary blending procedure , utilizing ZrH2,
reduces the formation of microcracks with only minimal microporosity. This marks a
substantial improvement over previous generations of L-PBF aluminum alloys, where
macro-cracking was a common issue and hindered large -scale adoption. This also
offers potential for other applications than L-P B F.
“Scandium Canada’s proprietary alloys directly address the critical need for printable, high-
strength, and lightweight metals in sectors such as aerospace, automotive, and advanced
manufacturing. This advancement is expected to accelerate the transition to lightweight
structures in critical applications, supporting global efforts toward sustainability, energy
efficiency, and improved engineering design ,” commented Dr. Luc Duchesne, Head of
Scandium+ division and Chief Science Officer.
Filing of a new international patent application
This innovation, developed in partnership with McMaster University, is now protected by a
new international patent application filed under the Patent Cooperation Treaty (PCT) on
September 17, 2025. This strategic move not only enhances Scandium Canada’s growing
intellectual property portfolio but also positions the company for commercial applications.
Short-term commercial opportunities study
An ongoing study with Productique Quebec announced on August 22, 2025, is currently
using the properties of Scandium Canada’s alloys to assess 10 short -term commercial
opportunities from a n extensive list of over 140 potential uses of Scandium Canada’s
scandium alloy s. Completion of this study is expected in mid-October 2025 and targets
several applications, in addition to laser powder-bed fusion (L-PBF).
