WM0433 Tungsten Rhenium Alloy Wire

Tungsten Rhenium Alloy Wire Description

Tungsten rhenium alloy wire belongs to refractory materials and has good ductility and strength. Tungsten rhenium alloys have a high melting point of 3050 °C and a high temperature of recrystallization of 1900 °C which makes it used in aerospace and temperature measuring applications. The addition of rhenium can increase the ductility after the wire recrystallizes. The specific resistance, as well as vibration strength, have been further improved. It has been widely used in the thermocouple market, joining, the medical, aerospace, furnace, and heat treatment industries.

Tungsten-Rhenium Wire has a density almost equal to Tungsten Wire and is commonly used in thermocouples and electronics products.
