99.95% Pure Tungsten Products Tungsten Crucibles W Crucible for Sapphire Growing Because of the high melting point(3410) of tungsten, tungsten crucible is widely used in the industrial furnaces such as sapphire single crystal growth furnace, quartz glass melting furnace, rare earth smelting furnace and other industrial furnaces of which the working temperature is over 2000â??. Especially for sapphire single crystal growth furnace, tungsten crucible with features of high purity, high density, no crack, precise size, smoothy internal and external wall is the key note to seed success rate, crystal quality control, off crystal stick pan and service life in sapphire crystal growth process. During sapphire production, Al2O3 - the compound that is to become the future single crystal - is melted in tungsten crucibles. It is in the Kyropoulos process that our crucibles show their strengths to best effect. They arerepeatedly heated to more than 2 000 �°C (3632 �°F) and then cooled down again. This process, which would cause fissures and distortions in other materials, is not a problem for our products.

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 . All tungsten rhenium wire is packaged per reel. 400g or 500g per reel. 250-260m per kilograms.
