Tungsten heavy alloy ball WNiCu
The Tungsten heavy alloy ball WNiCu is a solid spherical component manufactured from a tungsten‑nickel‑copper alloy. The alloy contains 90‑97 % tungsten with the balance of nickel and copper, delivering a density of approximately 18.5 g/cm³. Hardness values fall between HRA 90 and HRA 95, and the material tolerates temperatures up to 800 °C. These balls are supplied in standard and custom diameters to match OEM requirements.
WNiCu alloys are produced by powder‑metallurgy sintering, a process that yields high uniformity and excellent machinability. In the heavy‑alloy market the typical density range is 18.3‑18.6 g/cm³ and hardness is commonly HRA 90‑95, aligning with the figures provided. The nickel‑copper binder improves ductility compared with tungsten‑nickel‑iron alternatives, which is valued in precision applications. Dimensional tolerances of ±0.02 mm are standard for spherical parts of this size.
Primary users include aerospace manufacturers, automotive brake‑system makers, medical imaging equipment producers and defence contractors that require high‑density counterweights or shielding. Buyers typically request bulk shipments under FOB or CIF terms and may need ISO or SGS test reports, which should be confirmed with the supplier. The supplier offers flexible minimum order quantities, so importers should discuss exact batch size and packaging - usually bulk crates or steel drums - during negotiation.

Sourcing Tungsten heavy alloy ball WNiCu from Chengdu Woco Carbide Industry Co., Ltd. - China Import Guide
Before placing an order, importers should verify the exact tungsten content, hardness range and dimensional tolerance of the balls. Request the supplier’s material test report and, if required, an independent certification such as ISO 9001 or SGS conformity. Confirm whether the balls are supplied in the requested diameter and whether any surface finishing is applied. Checking these points reduces the risk of receiving parts that do not meet engineering specifications.
Logistics arrangements should be clarified early, including the preferred Incoterm - FOB from a Chinese port such as Shanghai or Ningbo, or CIF to the destination port. Ask the supplier to provide an estimated lead‑time based on the order volume and any required machining. Payment conditions, for example a telegraphic transfer after shipment or a documentary letter of credit, must be agreed in writing. Verifying these details helps avoid unexpected delays or additional costs.
Upon arrival, buyers are advised to conduct visual inspection for surface defects and to measure a sample batch for density and hardness using ASTM B21 and Rockwell methods. A third‑party inspection agency can verify compliance with the supplied material test report. Request accompanying documentation such as a certificate of conformity and a packing list that specifies crate dimensions and weight. Proper inspection and paperwork ensure the imported balls meet the required performance standards.
