Abstract
PURPOSE: To prevent insulation deterioration at high temperature, by using nickel- tungsten-molybdenum alloy as heat-generating wire of a sheath heater.
CONSTITUTION: When nickel-tungsten-molybdenum alloy is used as heat-generating wire of a sheath heater, the insulation deterioration at high temperature is reduced compared with the case where nickel-chromium is used. In particular, heat-generating wire for use at high temperatures, 600°C∼800°C, can be obtained.
