Description

Ni99.4Fe is a resistance alloy. With wire, the attainable tensile strength is 450 N/mm². The alloy distinguishes itself by a very high and exactly defined temperature coefficient of the electric resistance that is standardized according to DIN 43760. The upper application temperature in air is 750 °C, and it is 250 degrees C in case of an application for electric resistance thermometers according to DIN 43760. Ni99.4Fe can be soft-soldered and brazed without difficulty. All known welding methods are applicable. Application: Exclusively for the manufacturing of temperature-sensitive elements and electric resistance thermometers.
