ASTM B777 Tungsten Rod Bar Forged Diameter 100mm Tungsten Materials
ASTM B777 Forged Tungsten Rod Bar 30-2000mm Length
Tungsten has a high melting point, high-temperature strength, and creep resistance, as well as thermal conductivity, electrical conductivity, and electron emission performance, is good and the specificity is high. Low expansion coefficient and lowest metal vapor pressure. Generally use powder It is made by metallurgical methods.
Tungsten Rod Bar Availability
Tungsten rod is manufactured as random length pieces or cut to customers' desired lengths.
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.
Tungsten Rod Bar Surface Finish
Black - Surface is "as swaged" or "as drawn"; retaining a coating of processing lubricants and oxides.
Cleaned - The surface is chemically cleaned to remove all lubricants and oxides.
Ground - The surface is centerless ground to remove all coating and to achieve precise diameter control.
Tungsten content: 99.95%
Size: 2.0mm~100mm diameter Length: 50-2000mm
