99.95% Pure Tungsten Products Tungsten Rods Surface Black / Ground For Industry
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.
Tungsten Rods Availability
Tungsten rod 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.
