Tungsten is a metal element, and also a silver-white lustrous metal. It is mainly used to manufacture filaments, high-speed cutting alloy steel, superhard molds, and also used in optical instruments and chemical instruments. What is CNC Turning? Back To List The Composition of Cemented Carbide...
The high density makes it an ideal ingredient for darts, normally 80% and sometimes up to 97%. This allows darts containing tungsten to have a smaller diameter than those of other metals at the same weight, permitting tighter groupings. High speed steel contains tungsten and some tungsten ste...

Tungsten is similar in density to gold, scammers will coat tungsten bars in a thin layer of gold to create counterfeit gold bars. This trick is still used today and the scam can remain unobserved when thorough tests are not performed. As of 2020, China had the world’s largest tungsten r...
Tungsten Uses As filaments in old style of incandescent electric bulbs. They are not much used these days as they are not energy efficient[1]. It is alloyed with other metals or steel for strengthening them. The metal and its alloys have many high-temperature applications such as heating elem...
Surface hardening - uses tungsten and inert gas burner to treat defined zones without heat lossTo harden the surface of prods. of martensitic steel, a wolfram/inert gas burner is moved to and fro over the surface to be hardened, across the direction of material travel. Pref. the workpiece ...
Most of the manganese produced is used in the form of ferromanganese and silicomanganesealloysforironandsteelmanufacture. Manganese ores containing iron oxides are first reduced inblast furnacesor electric furnaces withcarbonto yield ferromanganese, which in turn is used in steelmaking. Adding manganese,...
Cemented carbides are used for rock and metal cutting. They can operate at 100 times the speed of similar tools made of steel. Health effects Tungsten has no essential role in the health of plants, humans, or animals. In moderate amounts, it also presents virtually no health danger. ...
