ALLVAR University
Learn More About Negative CTE and ALLVAR Alloys
Add negative CTE to your design toolbelt! At ALLVAR, we aim to provide resources to help innovators design and use negative thermal expansion in their projects and applications. ALLVAR University was established as a resource to help teach the fundamentals of designing with negative thermal expansion.
Video Library – ALLVAR offers a wide range of educational videos on the principals of thermal expansion. Learn how these properties fit into the design of optical and mechanical systems. Want to see negative thermal expansion in use? Check out the demo videos to see ALLVAR Alloys in action.
ALLVAR News and Blog – Dig deeper into the regularly updated blogs to learn more about specific ALLVAR Alloys use cases and news.
Papers and Presentations – Here you can find links to publications related to ALLVAR Alloys and externally published presentations.
