A tungsten alloy dart barrel is the main body component of a dart, precision-machined from high-specific-gravity tungsten alloy, providing the primary weight and gripping function of the entire dart. International dart rules define it as the detachable cylindrical section between the point and the shaft, constrained by upper limits on outer diameter, length, and total weight. Tungsten alloy achieves a microscopically dense skeleton through powder metallurgy by compounding tungsten particles with a binder phase, integrating high inertia and rigidity within an extremely narrow outer diameter. Functionally, it serves as center-of-gravity regulator, tactile feedback provider, kinetic energy transmitter, and modular interface: fingertip pressure determines micro-adjustment of the center of gravity, rigidity ensures no energy loss at release, and threads are compatible with standard points and shafts. In design, contours encompass straight, stepped, teardrop, torpedo, and bomb shapes, supporting front-weighted, center-weighted, and rear-weighted balance strategies. Surface processes include knurling, ring cuts, sandblasting, coating, and polishing, offering a full spectrum of frictional grip. The tungsten alloy dart barrel is essentially a precision engineering core that converts the player’s wrist biomechanical signals into predictable aerial trajectories, advancing dart sport from skill to systematic science. The introduction of tungsten alloy dart barrels has completely revolutionized dart design paradigms, enabling players to achieve ultimate center-of-gravity control and trajectory stability within rule-constrained volumes, becoming an irreplaceable core component in modern competitive darts.
