Tungsten alloys, with their high density (17-18.5 g/cm3), high strength (tensile strength up to 900-1200 MPa), and excellent corrosion and wear resistance, serve as critical components for optimizing power transmission, stability, and efficiency in automobiles. In traditional internal combustion engine vehicles, tungsten alloy counterweights are widely used in crankshaft and flywheel balance designs. The crankshaft, as the heart of the engine, has its operational smoothness affecting power output and noise control. Tungsten alloy counterweight blocks significantly reduce vibration and torque…
