ALTec Industrial R&D Group
With Canadian smelters producing more than 50% of the aluminium used in the North American market, Canada has taken a leadership role in expanding the use and acceptance of aluminium in manufactured products. The National Research Council of Canada is spearheading national research efforts for the development of innovative aluminium products for ground transportation vehicles.
ALTec industrial R&D group is a multi-client collaboration project which allows its members to share costs and risks, associated with aluminium R&D, and gain access to NRC's experts and exceptional facilities, all under one roof. ALTec's activities are focused on three areas of R&D: manufacturing of advanced aluminium components; assembly of aluminium and multi-material components; and durability and performance evaluation and solutions.
What is ALTec?
ALTec is an industrial R&D Group that brings the latest advancement related to aluminium manufacturing and assembly to its member companies. ALTec acts as an innovation catalyst by creating a research community involving participants from the entire value chain, from raw material manufacturers to major prime contractors whose main interest lies in lightweighting vehicles and land transportation through the use of aluminium.
The goal of ALTec is to solve common industry challenges through pre-competitive research projects. The results of these projects will improve member companies' capabilities in manufacturing, assembling and evaluating the durability of advanced aluminium or multi-material components with tailored properties.

"NRC helped us validate and understand corrosion's effects on the assembly of dissimilar metals. Concrete results supported by clear explanations have enabled us to develop new, lighter and less costly designs while minimizing the risks identified at the start of the project." – David Croteau, Eng., Mechanical Product Expert, Prévost
