Tungsten Rhenium Wires

Tungsten rhenium wire is a kind of alloy wire composed of tungsten as the matrix and different content of rhenium elements. This alloy wire has a variety of advantages, including higher melting point, higher strength, greater hardness, lower vapor pressure, higher recrystallization temperature and resistivity These advantages include higher melting point, higher strength, greater hardness, lower vapor pressure, higher recrystallization temperature and resistivity, as well as good plasticity, ductility, creep resistance, mechanical properties, and workability. The amount of rhenium added is usually between 1% and 5%, but can be adjusted to meet specific application requirements, e.g. typical rhenium contents include 1%, 3%, 5%. 20%, 25% and 26%, etc.
Tungsten rhenium wire is widely used in the electric power industry, especially in the need to solve the problem of wire expansion at high temperatures and provide stable power transmission. In addition, tungsten rhenium wire is also used in some of the requirements of high reliability of electric light source products to prevent filament breakage, through the doping of silicon, aluminum, potassium and other elements to improve material High-temperature performance, so that the tungsten delayed brittle transition temperature down to room temperature or below room temperature
