ALLVAR Alloy 30 is unique with a negative thermal expansion coefficient of −30 ppm/°C at room temperature, or a 1-meter rod shrinking by 0.003 mm for every degree Celsius rise.

The behavior of distinct materials, when subjected to different temperatures at consistent pressures, is known as the coefficient of thermal expansion (CTE). This value is expressed as n x 10 -6 /K ...

Kondo effect induces giant negative thermal expansion The researchers say that this is the first time anyone has observed a magnetic-field-induced change in the sign of a material’s CTE. “Our study ...

They simply call it Alloy 30, probably on account of the fact that is shows a -30 ppm/°C coefficient of thermal expansion at room temperature – in words we can all understand, a one-meter (3.3 ...

Summary The results indicate that the TMA 4000 can precisely estimate the coefficient of thermal expansion of numerous well-characterized materials. Due to its low CTE and poor thermal conductivity, ...

The new SEQUEL 1828 polyolefin exhibits a coefficient of linear thermal expansion (CLTE) that is the lowest of any material the company has yet developed.
