high quality tungsten rod tungsten bar

Tungsten Rodit can be used as High-temperature heat source and High-temperature structure accessory. Tungsten Rod Main Applications: Manufacture electric light source and electric vacuum accessory. It can be used for make Electrical contact.For stirring purposes in rare earth metals smelting and for making tungsten contacts and parts in electrical light sources making Tungsten's unique properties, 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 Sifon produces pure and potassium doped (WK Type) tungsten rod The potassium doped products is targeted for use where high temperature non-sag properties are required in smaller cross sections by the lighting and electronic industries Availability: Tungsten rod is manufactured as random length pieces or cut to customers' desired length Standard diameter and length tolerances are listed in the accompanying tables Other, closer tolerances can be quoted on request 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 At present, we can supply you 99.98%of tungsten bar with a very competitive price. The monthly production ability is 120m/t. Product specification: 12 *12* (550)mm. Packing: wooden case.
