We are in the process of getting negative CTE ALLVAR Alloys into space, and we expect to achieve that goal within the next 1-2 years. ALLVAR Alloys are true Titanium alloys and behave as such. We do not foresee any problems with ALLVAR’s performance in space. You can read about our projects to bring ALLVAR Alloys to space here or contact us to see what we can do in space.
