Application
Tungsten rods (tungsten alloy rods) are mainly used as heater, support pillar, feeder and fastener in vacuum or reducing atmosphere high temperature furnace. Moreover, serve as light source in lighting industry, electrode in glass and tombarthite melting, and welding equipments.
Description
Tungsten rod can be manufactured in random length pieces or cut to meet customers' desired lengths. There are three different surface processes which are provided upon the desired end use.
1. Black tungsten rod - Surface is "as swaged" or "as drawn"; retaining a coating of processing lubricants and oxides.
2. Cleaned tungsten alloy rod- surface is chemically cleaned to remove all lubricants and oxides.;
3. Ground tungsten rod- Surface is centerless ground to remove all coating and to achieve precise diameter control.
Features
The outstanding feature is that they can be batch operated. Among the rod-like metal materials, tungsten alloy rod has the highest melting point. In heat, electric conduction and electron emission, it performs very well. The tungsten rod is also characterized by high density, low dilatation coefficient and lowest metallic vapor pressure. The density is higher than 18.8g/cm3; purity, 99.5%. This has met the GB 4187-84 and AKM QB/WB-2006 Standard.
Theoretical Density: 19.3g/cm3
Melting Point: 3422℃
Electric Condctivity: 30% IACS Min
Rigidity: 69 HRA Min

Package and Inspection
We offer material composition sheet and examination report which include density, flaw detection, dimensions, and so on. Our products are packed in plywood case with expanded plastic. What's more, the case is moistureproof and grooved for products being placed stably.
Achemetal Furnace Co., Ltd manufactured tungsten rods with high density and excellent match inability. Our company forges different types of tungsten alloy rods, bars and blocks by using tungsten, molybdenum, TZM and Mo-La alloys. Above 60% of our products are exported to more than ten countries and areas, such as USA, Germany, Japan, Russia, South Korea, etc. Meanwhile, parts of them are selected and used by nonferrous metals research institutes.
