Tungsten rod is produced by pressing and sintering into billets, which are worked by rolling or swaging into rod. Smaller sizes are produced by subsequent drawing. Tungsten rod is produced in straight random lengths with a smooth swaged surface at diameters 3mm and larger, and with a smooth drawn finish below 3mm. A centerless-ground finish can also be furnished. Specific lengths and special fabrications can be supplied upon request.
These kinds of rods could be machined further, which are usually used to making the parts of counterweights, radiation shielding, military defense appliance, welding rod, extrusion die, radiation shielding , also for some sports fields, such as darts, billets, golf club, etc.
