The tungsten alloy dart barrel is the main body of a dart, precision-machined from a tungsten alloy shaft to provide primary weight and grip function. The classification of tungsten alloy barrels can be made from multiple perspectives: by tungsten content, they fall into three categories (high-tungsten, low-tungsten, and medium-tungsten); by appearance shape, they are divided into torpedo, barrel, and straight types; and by surface texture, they include knurled, ringed, smooth types, among others.
By tungsten content, high-tungsten barrels offer higher density, slimmer bodies, smaller cross-sections, minimal air resistance, stable flight paths, and minimal landing-point disturbance from tail fins—ideal for pros chasing tight groupings. Medium-tungsten barrels strike a cost-vs-slimness balance, with moderate diameters that deliver both stability and affordability, making them the mainstream choice for clubs, online events, and semi-pro players. Low-tungsten barrels have thicker walls for a solid grip feel, budget-friendly pricing, and larger diameters that help beginners sense the centre of gravity, build throwing muscle memory, and lower the entry barrier.
By appearance shape, torpedo barrels are thick at the front and thin at the rear, with forward-shifted weight that slices airflow and suppresses turbulence for straight long-range paths—perfect for power-push techniques and strength players. Barrel-shaped barrels bulge in the middle with centre-balanced weight and low moment of inertia, offering instant balance on release, high adoption rates on the PDC tour, and reduced fatigue during continuous throwing. Straight barrels maintain uniform diameter and centred weight, allowing grip anywhere along the front, middle, or rear, accommodating different throwing stages and ideal for players in technical transition.
By surface texture, knurled barrels weave dense raised points into an anti-slip net with high static friction, staying locked in sweaty conditions—perfect for hot, humid venues or tense finals. Ringed barrels feature deep lateral cuts that create positioning steps, letting fixed-grip players achieve sub-millimetre resets for high throwing repeatability. Smooth barrels receive mirror polishing or laser micro-grooving for low dynamic friction, dropping release resistance instantly so the dart slips away silkily—suited to fluid techniques chasing ultimate exit speed.
