WRe

[WRe3, WRe5, WRe26]

Tungsten-rhenium alloys combine the very high melting point of W with the ductility-enhancing properties of Re. Compared to pure tungsten, WRe grades exhibit a higher recrystallization temperature, greater strength and significantly better ductility; they are also easier to weld or solder. They are frequently used for thermocouple wires as well as cables and filigree components exposed to high temperatures. Below you will find the standard grades (WRe3, WRe5, WRe26) with compositions, available shapes and data sheets.

Grades & data sheets

Variety	Composition	Available as	data sheet
WRe3	W 97% / Re 3%	Wires, filaments, foils, rods, parts according to drawing	Material data sheet
WRe5	W 95% / Re 5%	Wires, filaments, foils, rods, parts according to drawing	On request
WRe26	W 74% / Re 26%	Wires, filaments, foils, rods, parts according to drawing	On request

The key features are as follows: High recr. temp., ductile; good weldability/solderability; thermocouples
