VDM MetalsControlled Expansion Alloys

SHARE

Our controlled expansion alloys are characterized by extremely low thermal expansion coefficients at low- as well as in high-temperature ranges; furthermore, they possess good ductility and toughness, as well as good mechanical properties and a low propensity to fatigue at low temperatures.
