Detailed Description
Place of Origin Shaanxi, China (Mainland) Brand Name GETWICK Model Number WAl1 WAl2 WAl3 W1 W2 Shape round bar Feature refractory,Corrosion preventing EINECS 2231-143-9 CAS 7440-33-7 Boilling Point 5660 Melting Point 3410℃ Molecular Weight 183.84 Application Aerospace, lighting,etc. Pure Tungsten rod Tungsten's unique properties as a high performance material, including a melting point of 3410° C, low vapor pressure at elevated temperatures and low coefficient of thermal expansion, make it of value in a variety of high temperature products and processes. Among them are glass-to-metal seal parts and support parts for lighting and electronics, silicon rectifier stud mounts and high temperature furnace components. Elmet produces pure and potassium doped tungsten rod. The potassium doped products are targeted for use where high temperature non-sag properties are required in smaller cross sections by the lighting and electronic industries. Tungsten rods/bars are mainly used in the manufacture of various of emission cathode, filament, high temperature, stereotypical bar, support, lead wires, print needles, various electrode, quartz furnace, heater and so on. Tungsten rods/bars extensively processed into Reamers, Drill Bits, Milling Cutters, Endmills,Face Millis,Shell Mills, Burs, Boring Cutter, Countersink Cutters, Gun Drills, Thred Shavers, Gravers,Solid Engraving Tools,Solid Burrs,. All our carbide rods are made from Extrusion method and HIP Sintered. . Availability of Pure tungsten rods Tungsten rod is manufactured as random length pieces or cut to customers' desired lengths in diameters ranging from .020 inches to .750 inches. Standard diameter and length tolerances are listed in the accompanying tables. Other, closer tolerances can be quoted on request. In addition, there are three different surface processes or finishes which are provided, depending upon the desired end use. 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. Our products is available in a wide range of forms including nut, screw ,ring ,wire, foil, sheet, rod, strip, plate, tube, alloys according to Standard ASTM AMS ASME MIL DMS JIS GB, etc. As a DNV certified ISO9001:2000 company, we have strict quality control system and provide professional service to our customers around the world. Our customers are in aerospace industry, chemical equipment industry, medical industry and civilian industry in USA, UK, Germany, Sweden and some other countries.
