Description

The expansion material NiFe47 is to a large extent applied for glass sealings in soft glasses. It possesses a relatively low thermal expansion up to approximately 450 °C. (Temperature interval RT to 400 °C: coefficient of thermal expansion 9.7 to 10.5 10^-6 K^-1). The alloy is of relative durability at normal temperatures in air with normal weather conditions as well as in fresh water and sea water. NiFe47 is well weldable by using the tungsten inert-gas method.
