Black Machined Surface Tungsten Products 10mm - 1100mm Tungsten Round Bars

Tungsten Products Pure Tungsten Round Bars With Black / Machined Surface

Features of Pure Tungsten Material

Tungsten is resistant to corrosion when the humidity is below 60%. However, it must be protected at elevated temperatures. Tungsten can oxidize in the presence of oxidizing gases at temperatures above 250° C. Despite this vulnerability, Molten glass, nitrogen, inert gases, molten metals and ceramic oxides only slightly affect it.

1. High melting point.

2. Unique low coefficient of thermal expansion.

3. The very high level of dimensional stability.

4. High Density no less than 19.1g/cm3

Tungsten Round Bars Availability

Tungsten round bar is manufactured as random length pieces or cut to customers' desired lengths. Standard diameter and length tolerances are listed as follows. 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.

Application of Tungsten Round Bars

The tungsten round bars are used in the manufacturing of electric light source and electric vacuum parts. They are the wonderful electric shock materials. At the meantime, the tungsten rods are used as a means of high temperature and high temperature structure parts. In the rare earth, they are also used as the electrode. The tungsten round bars are also used in the filament, cathode and components for electron tubes, electrode for the gas discharge tube and so on. They are appeared in the grid siderod, lead, support, electrode for the discharge lamp and others. Nevertheless, they can be in the grid siderod, support, lead and electrode and so on.
