Product Description
- Features:
- Dimensions: according to customer's requirement
- Densities: 15.8-18.50 g/cm3
- Composition: W content: 80-97%, W-Ni-Fe, W-Ni-Cu
- Surface: Sinter state, polish state, swaged state
- Introduction:
- Produced by pressing and sintering into billets, which are worked by rolling or swaging into rod
- Smaller sizes are produced by subsequent drawing
- Produced in straight random lengths with a smooth swaged surface at diameters 3mm and larger, and with a smooth drawn finish below 3mm
- A center less-ground finish can also be furnished
- Specific lengths and special fabrications can be supplied upon request
- 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:
- Could be machined further, which are usually used to making the parts of counter weights for oil logging, artillery, rocket, satellite, aircraft, boats
- Radiation shielding, military defense appliance, armor-piercing bullet, welding rod, the aerospace, mechanical manufacture, extrusion die, also for some sports fields, such as darts, billets, golf club & more
- Standard:
- ASTMB777-15
Surface: Sinter state, Grind state, processing state with chamfer angle
