- Product Definition
Tungsten alloy disc is circular metal plates made primarily from high-percentage tungsten (typically 90–97%), alloyed with elements such as nickel (Ni), iron (Fe), or copper (Cu). They are manufactured through powder metallurgy, hot isostatic pressing (HIP), and precision machining processes. Based on thickness, they can be classified into thin discs, thick discs, and high-precision round plates.
- Key Performance Features
| Property | Description |
| High Density | Typically 17.0–18.8 g/cm³, allowing compact yet heavy design. |
| Excellent Mechanical Properties | High strength and hardness with outstanding impact and wear resistance. |
