2% thoriated tungsten electrodes(EWTh-2) is the rare earth tungsten electrode which uses most early, is also the best tungsten electrode in welding performance until now , therefore, this tungsten electrode(EWTh-2) market share is globally highest, but because of the radioactive contamination in the powder metallurgy and the rolling process, European ,American developed countries limited to use the 2% thoriated tungsten electrodes(EWTh-2).because of its fine welding performance, its use has not been restricted. Thorium is a low-level radioactive material that primarily emits alpha particles as well as some beta and gamma radiation. However, if welding is to be performed in confined spaces for prolonged periods of time or if electrode grinding dust might be ingested, special precautions relative to ventilation should be considered. The user should consult appropriate safety personnel. So many users have switched to other alternatives. 2% thoriated tungsten electrodes are widely used because they make good welds and are long lasting and quite easy to use. A thoriated tungsten electrode operates at a temperature well below its melting temperature. this tungsten electrode is used primarily for DC welding and may split if used for AC welding Material welded is primarily Aluminum and Magnesium
All 2% thoriated tungsten electrodes is packaged 10 pieces of 150mm or 175mm.
Special diameters and lengths are available, please contact sales for inquiries.
10 pieces of 150mm or 175mm. Diameter 0.5-12mm.
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.

Due to the manufacturing advantages of tungsten rods, tungsten sheets, tungsten machining parts and tungsten processing equipment, Sunstone established a Division of hot zone of sapphire crystal growing since 2008. Until now Sunstone provided a large number of hot zone parts like crucibles, sheet and rods to Russia, Ukraine, USA, Japan, Korea, Thailand, Singapore Taiwan and Hong Kong. So now we have been gradually formed the capacity of 30 sets hot zone in 35Kg, 65Kg, 85Kg and 120Kg.
Sunstone has a sound quality management system of ISO9001 and ISO14001 and get the certification. Sunstone has a excellent testing equipment of physical properties like density, hardness, surface roughness, grain size, tensile strength and other parameters, even ultrasonic NDT.
The distinguishing characteristic of Sunstone 's tungsten crucible is high density, high purity and high precision machining. As the whole set of hot zone parts is completed in Sunstone , so the quality between the components is to get a good guarantee. With its excellent quality and reasonable price has been widely recognized by the industry of sapphire crystal growing and hot zone furnace at home and abroad, Sunstone has been designated the sole supplier and leader in domestic and foreign industry.
Because of their excellent corrosion resistance again sapphire melt and their high temperature creep resistance, tungsten crucibles are used for sapphire crystal growing in all common processes.

Tungsten, as a high performance material, has unique properties: highest melting point, low vapor pressure, low coefficient of thermal expansion, Tungsten bars or rods is often used for producing ion implantation parts. Tungsten electrode, electric light source parts and electric vacuum components. In high temperature furnace,tungsten rods or bars is used in producing heating elements and heating parts.
Surface Finish
Black - Surface is "as swaged" or "as drawn"; retaining a coating of processing lubricants and oxides.
Cleaned - Surface is chemically cleaned to remove all lubricants and oxides.
Ground - Surface is centerless ground to remove all coating and to achieve precise diameter control.
