COLLEGE STATION, Texas - ALLVAR, a manufacturer of alloys that exhibit negative thermal expansion (NTE), has been awarded a NASA SBIR Phase I Grant to develop a new high temperature NTE alloy. The new alloy, ALLVAR Alloy-HT, is expected to improve the reliability and reusability of future high temperature planetary and lunar mission systems by compensating the expansion effects of other materials.
ALLVAR expects this new alloy to withstand temperatures from -200°C to 500°C, enabling NASA’s reusable moon mission hardware and the exploration of Venus with reliable and stable instruments.
This is the third NASA SBIR award ALLVAR has received and the first for high-temperature alloy development. The company is currently developing structural supports for space telescopes with picometer level stability made in part with previous ALLVAR Alloys developed from SBIR grants.
