Tungsten Heavy Alloy Rod
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.
1. Dimension: according to customer's requirement.
2. Density: 15.8-18.50 g/cm3
3. Composition: W content: 80-97%, W-Ni-Fe, W-Ni-Cu
4. Surface: Sinter state, polish state, swaged state
The main performance of the tungsten alloy
Small size with high density, high melting point , high hardness , excellent wear resistance , high ultimate tensile strength , extension of good , low vapor pressure , heat resistant, good thermal stability , easy processing, corrosion resistance, good shock resistance , high radiation absorption capacity , excellent impact resistance and crack resistance , and non-toxic environmental protection Is consistent with international environmental protection standards.
Appliance of tungsten heavy alloy rod
These kinds of rods could be machined further, which are usually used to making the parts of counterweights for oil logging, artillery, rocket, satellite, aircraft, boats; radiation shielding, welding rod, the aerospace, mechanical manufacture, extrusion die, also for some sports fields, such as darts, billets, golf club, etc.
