Scandium Canada updates on its proprietary Aluminum-Scandium Alloys

(TheNewswire)

Montreal, QC – TheNewswire - September 25, 2025 — Scandium Canada Ltd. (TSXV: SCD ) (OTC: SCDCF) is pleased to announcethat new data on the properties of its modified AA535 and AA7075alloys confirm an economically viable technological advancement in thefield of aluminum-scandium (Al-Sc) alloys explicitly developed foradditive manufacturing applications. The current results are focusedon the properties of samples printed through the laser powder-bedfusion (L-PBF) process. The company’s latestresults substantiate that Scandium Canada’s alloys offer a practicalsolution to one of the most persistent challenges in metal 3Dprinting: eliminating cracking in high-strength aluminum alloys, whichpaves the way for a new era of lightweight, high-performance, andcost-effective components across multiple industries. See pressrelease : Scandium Canada updateson aluminum-scandium 3D powders research anddevelopment . Itshould be noted that Scandium Canada has established a division withinthe company, Scandium + , dedicated explicitly to ramp up commercialization effortsfor 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 corporatestructure .

Scandium + 's mainobjectives are to :

• Deploy scandium in markets with the highestneeds.

• Commercialization of patent-pending Al-Sc alloys withpotential in multiple sectors (AA7075/Sc/Zr AA535/Sc/Zr/Ce).

• Focus on value-added Scandium alloys.

The main attributes of ScandiumCanada’s Al-Sc powders include:

• Reduced Scandium Content: Thetechnology enables significant reductions in the amount of scandiumrequired, directly addressing cost and resource sustainability. Thealloys maintain the grain-refining effect necessary to eliminate hotcracking during L-PBF processing, making high-quality productionpossible at lower material expense.

• Broad Processing Window: Thenewly developed aluminum-scandium-zirconium alloys exhibitprintability across a wide range of laser power and scanning speedparameters. Testing has confirmed relative densities above 99% underoptimal conditions, a key measure for component integrity andreliability.

• Suitable MechanicalProperties: 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: Theproprietary blending procedure, utilizing ZrH2, reduces the formationof microcracks with only minimal microporosity. This marks asubstantial improvement over previous generations of L-PBF aluminumalloys, where macro-cracking was a common issue and hinderedlarge-scale adoption. This also offers potential for otherapplications than L-PBF.

“Scandium Canada’s proprietary alloys directly address thecritical need for printable, high-strength, and lightweight metals insectors such as aerospace, automotive, and advanced manufacturing.This advancement is expected to accelerate the transition tolightweight structures in critical applications, supporting globalefforts toward sustainability, energy efficiency, and improvedengineering design,” commented Dr. Luc Duchesne, Head of Scandium + division and Chief ScienceOfficer.

Filing of a new international patentapplication

This innovation, developed in partnership with McMaster University, isnow protected by a new international patent application filed underthe Patent Cooperation Treaty (PCT) on September 17, 2025. Thisstrategic move not only enhances Scandium Canada’s growingintellectual property portfolio but also positions the company forcommercial applications.

Short-term commercial opportunitiesstudy

An ongoing study with Productique Quebec announced on August 22, 2025,is currently using the properties of Scandium Canada’s alloys toassess 10 short-term commercial opportunities from an extensive listof over 140 potential uses of Scandium Canada’s scandium alloys.Completion of this study is expected in mid-October 2025 and targetsseveral applications, in addition to laser powder-bed fusion (L-PBF).
