tungsten bar

Detailed Product Description

Tungsten Bar can be used as High-temperature heat source and High-temperature structure accessory.

Tungsten Bar

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 Bar  is manufactured as random length pieces or cut to customers' desired lengths in diameters ranging from 0.020 inches to 0.750 inches

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
