Tungsten bar is most widely used in steel making. In the steel making industry, steel making tungsten bar is usually applied as an additive. The purity is at least 99.93% according to Chinese Standard. Steel making tungsten bar is also used as found ingredient of material, cutter and heads, tungsten wire for lights instruments, electric contact points and conductor of heat, crankshaft and cylinder barrel of advanced automobile, ingredient of kinds of heat-resistant steel.
Mainly used for foundry materials tool bit of processing lathe, and conductors, steel-making burdening and additives crankshaft and cylinder burdening and electrodes for advanced automobiles for the manufacture of guns, artillery, rockets, satellites, aircrafts and ships.
Steel making tungsten bar are also used for making special steels, to make guns, artillery rockets, satellite airplane and ship. It has a luster rather like that of silver in uniform color. Though the whole bar may slightly curve, the maximum height of the bend should not be more than 7mm.
