Tungsten rhenium wire(WRe wire) is an alloy wire formed with tungsten and rhenium metals. Tungsten rhenium wire has a lot of advantages such as high strength in room and high temperature, good ductility after recrystallization, large resistivity, low coefficient of resistance, resistant to oxidation and carbonization, anti-"water cycle response" ability and welding performance In recent years, tungsten rhenium wire are widely exported to Taiwan, Japan, Korea, Russia , Ukraine and other countries because of the sapphire of single crystal growth, so WRe25 (tungsten 75%--Rhenium 25%) with diameter of 0.5mm is the most commonly used . Diameter: 0.5mm 400g or 500g per reel. 250-260m per kilograms.
