Products Description
Manufacturer supply High quality 99.95% Tungsten rectangular bar
can be manufactured in random length pieces or cut to meet customers' desired lengths. There are three different surface processes which are provided upon the desired end use:
1. Black tungsten bar - Surface is "as swaged" or "as drawn"; retaining a coating of processing lubricants and oxides;
2. Cleaned tungsten bar- Surface is chemically cleaned to remove all lubricants and oxides;
3. Ground tungsten bar Surface is centerless ground to remove all coating and to achieve precise diameter control.
