Copper Ball
Zhong Shan H.R.T. Precision Steel Ball Co., Ltd. manufactures copper balls made from electrolytic copper with a purity of Cu 99.99 % (CW004A / C11000). The balls are offered in diameters from 1.0 mm up to 25.4 mm, covering a broad spectrum of precision applications. These spheres are classified under HS code 7403.90 for unwrought copper, which is standard for non‑ferrous metal exports. Each ball features a low coefficient of friction, facilitating smooth axial and radial movement in mechanisms.
In the precision ball industry, copper balls of this grade typically exhibit a Brinell hardness of 70‑80 HB and a sphericity deviation of less than 0.005 mm, which ensures reliable performance. Standard tolerances for size are ±0.005 mm for the 1‑10 mm range and ±0.010 mm for larger diameters, while surface roughness is usually Ra ≤ 0.2 µm after grinding and polishing. Manufacturers often package the balls in sealed plastic bags placed within wooden crates to protect against contamination; this is a typical delivery method.
The balls are commonly used in valves, spray nozzles, instruments, pressure gauges, carburetors and other precision equipment. Potential buyers include valve manufacturers, automotive component makers, and industrial equipment suppliers. The supplier’s listing does not disclose minimum order quantity, lead time or payment conditions, so importers should request these details directly. Custom packaging or surface treatments can be discussed during negotiation, as is usual for precision metal components.

High-purity copper balls are manufactured in sizes ranging from 1.0mm to 25.4mm, suitable for valve, spray, instrument, and pressure gauge applications. These copper spheres feature a low coefficient of friction enabling smooth axial and radial movement. Exported globally in standardized packaging, copper balls are classified as unwrought copper and subject to standard non-ferrous metal trade regulations.

Sourcing Copper Ball from Zhong Shan H.R.T. Precision Steel Ball Co., Ltd. - China Import Guide
Before committing to purchase, verify that the copper balls meet the stated 99.99 % purity by requesting an independent material analysis report. Confirm that the product complies with any destination‑specific non‑ferrous metal regulations and that the HS code 7403.90 is correctly applied for customs clearance. Ask for a detailed technical data sheet that lists size tolerances, hardness and surface finish to avoid mismatches later.
Shipping copper balls from China generally involves consolidation at ports such as Shenzhen or Guangzhou, with sea freight as the most common mode. Discuss preferred incoterms with Zhong Shan H.R.T. and obtain an estimated lead time, as the listing provides no timeline. Payment by irrevocable L/C or telegraphic transfer (T/T) is typical for precision metal components, but the exact terms should be documented in the sales contract.
Arrange a pre‑shipment inspection to verify size tolerance, hardness and surface roughness against the agreed specifications. Request a quality control report that includes dimensional inspection data and any relevant material test certificates. Ensure the commercial invoice, packing list and certificate of origin are supplied to facilitate smooth customs processing and reduce clearance delays.
