Tungsten Alloys

        Tungstenhas the highest melting point and the lowest vapors pressure among all the metals, which makes it a preferred candidate for use as a high performance material in a variety of high temperature products and processes. QQ截图20171010162358.jpg
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.
