Properties: Tungsten (W) is one of thestrongest pure metals, with a tensile strength of 450-1300 MPa and Vickers hardness of HV 1500-2500. It has exceptional high-temperature stability, retaining hardness even at 1000°C, and a high melting point (3422°C).
Advantages: Boasts superior heat resistance far outperforming steel and titanium alloys; when alloyed into tungsten carbide, it gains excellent wear resistance. Its rigidity from covalent bonds ensures long service life in harsh conditions.
Applications: Core component of tungsten carbide (one of the strongest alloys) for CNC cutting tools; used in high-temperature precision components like aerospace engine parts; ideal for wear-resistant precision cutting tools (e.g., 6% Co WC-Co alloys for machining).
