YW1 tungsten carbide bars YW1 YW1 YW1 tungsten alloy steel chemical composition: wc: 84%, co: 6% TAC: 3% Density: 14.3 Hardness: 90HRA-91HRA bending strength: (σbb / MPa): 1400 Impact toughness : σK / (J/cm2): 0.3 Application: silicon steel sheet, cold rolled sheet, suitable for the production of drawn mold, wear-resistant parts and stamping parts and carbide automatic presses punch and so on. Use strength and impact toughness, wear resistance than the alloy is low. Top load large forging dies, such as for screws. Rivet upsetting die. Also used for stamping die. Extrusion die. Die and so on. For volume production, with excellent strength and toughness, suitable for the production of drawn mold, wear-resistant parts and stamping parts and carbide automatic presses punch.
