Tungsten Alloy Spheres 2–12mm, Heavy High-Density Balls for Balancing & Grinding For Sale

These high-density tungsten alloy balls are manufactured from W-Ni-Fe alloy containing about 95% tungsten, offering a density of approximately 18 g/cm³. The compact and heavy metal spheres provide reliable performance for laboratory applications where high mass in a small volume is required.
The tungsten balls are precisely formed with smooth spherical surfaces and multiple diameter options ranging from 2 mm to 12 mm. Their durable structure makes them suitable for laboratory grinding media, counterweight beads, calibration components, and research experiments.
Because tungsten alloy combines high density with good mechanical stability, these metal spheres are widely used in scientific research, engineering tests, precision balancing, and laboratory setups.
