WCball Tungsten Carbide Milling Balls Ø3-10mm, 20 Balls per Package, High Hardness and Density for Lab Milling
WCball milling balls are designed specifically for laboratory milling tasks that require durable and dense grinding media. These tungsten carbide balls are ideal for use in tungsten carbide jars, ensuring compatibility and optimal milling efficiency. Their exceptional hardness and density make them suitable for grinding tough samples with minimal wear and contamination.
The balls feature a spherical shape with a flat band, known as the satellite design, which enhances milling performance by improving contact and reducing ball agglomeration. Available in four diameter sizes—3 ± 0.3 mm, 5 ± 0.3 mm, 8 ± 0.5 mm, and 10 ± 0.5 mm—these balls provide flexibility to match different milling jar sizes and sample requirements. Each package contains 20 balls, and customers can select the desired size and quantity accordingly.
