ALLVAR Alloys are the only Negative Thermal Expansion Metals in the World
ALLVAR Alloy 30 is the first negative thermal expansion metal with a coefficient of thermal expansion (CTE) of -30 ppm/°C at 20°C.
This new property opens the door for engineers to control thermal expansion across a wide range of applications.
