2.4475 (DIN 17745 : 2002-09)	2.4475	DIN 17745 : 2002-09	Supersedes DIN 17745 : 1973-01	Valid	Germany	The expansion material NiFe46 with the material number 2.4475 is applied in 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 9.8 to 10.6 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. NiFe46 is well weldable by using the tungsten inert-gas method.
