Tungsten Carbide Grinding Ball Bearing Ball
Chengdu Woco Carbide Industry Co., Ltd. produces tungsten carbide grinding and bearing balls that are sintered from a WC matrix with either cobalt or nickel binder. The balls are precision‑engineered for high‑wear applications and can be supplied in a range of diameters according to customer drawings. The listing notes that the material offers exceptional hardness, wear resistance and thermal stability for demanding industrial use.
Typical binder content for WC‑Co or WC‑Ni carbides is 5 % - 12 % by weight, delivering hardness values in the 90‑95 HRA range, which is standard for grinding media. Grain size is usually controlled to below 1 µm to ensure a fine microstructure and consistent performance. Density for these carbides is about 15.6 g cm‑3 and thermal conductivity lies between 70 and 85 W m‑1 K‑1, both typical for high‑grade cemented carbides. Dimensional tolerance for spherical balls is commonly ±0.005 mm, a standard specification for bearing‑grade components.
The balls are employed in ball bearings, valve seats, grinding media, high‑stress mechanical systems, and specialised aerospace or oil‑and‑gas equipment. Buyers such as bearing manufacturers, pump and valve producers, and mining‑tool makers source them in bulk for assembly lines. The listing does not disclose minimum order quantity, lead time or payment conditions, so interested importers should request those details directly from the supplier. Shipping is usually arranged in bulk containers, with Incoterms negotiable per contract.

Sourcing Tungsten Carbide Grinding Ball Bearing Ball from Chengdu Woco Carbide Industry Co., Ltd. - China Import Guide
Importers should first confirm the exact binder composition, grain size and hardness that match their performance requirements. Requesting a mill test report or a third‑party hardness certification will provide evidence that the balls meet the stated technical parameters. Verifying the supplier’s business registration and trade credentials is also essential before finalising any purchase.
Logistics for bulk carbide balls are typically arranged under FOB or CIF terms, but the exact Incoterm, container loading plan and payment schedule are not disclosed in the listing. Buyers must negotiate lead‑time, shipping method and payment conditions directly with the supplier. Ensure that the packaging protects the spherical balls from impact and moisture during transit.
Quality control usually involves hardness testing, dimensional inspection of each ball batch, and visual examination for surface defects. Engaging a pre‑shipment inspection agency can verify compliance with the agreed specifications. Ask the supplier for a certificate of conformity or a detailed test report to document that the delivered product adheres to the required standards.
