The Zoom 1.5mm-20mm Copper Balls are precision‑machined spheres supplied by Zhong Shan H.R.T. Precision Steel Ball Co., Ltd. Each ball is produced from electrolytic copper with a purity of 99.99 % Cu, ensuring excellent electrical conductivity. The product range covers diameters from 1.5 mm up to 20 mm, with a uniform spherical tolerance suitable for automated assembly. These attributes make the balls appropriate for high‑density PCB manufacturing and related electronic assemblies.
Electrolytic copper of this grade is the standard material for conductive components in the electronics sector, offering resistance to oxidation and stable performance over temperature cycles. In the industry, similar copper spheres are classified under C11000 (ECP) grade and are often supplied with a surface roughness of Ra 0.2 µm to minimise contact resistance. Typical hardness for such balls lies around 70 HB, which balances wear resistance with manufacturability. The balls are usually packed in bulk containers, such as 25 kg cartons, to facilitate high‑volume handling.
End users include PCB fabricators, connector manufacturers and suppliers of conductive fillers for polymer composites. Importers can request bulk packaging under FOB or CIF terms, with payment options including L/C or T/T as noted in the supplier’s standard trade conditions. Because the supplier’s response rate is currently recorded as 0 %, buyers should confirm lead times and minimum order quantities directly before placing an order. The combination of material purity and dimensional consistency supports reliable performance in electronic hardware.

Zhong Shan H.R.T. Precision Steel Ball Co., Ltd. is located in Zhongshan, Guangdong Province, China, as indicated by its registered address in Shenchong Industrial Park. The company holds a harbor‑tier verification on the platform, signalling that its business credentials have been cross‑checked, although its recorded response rate is currently 0 % and average response time is not available.
The supplier specialises in the manufacture of precision steel and copper balls for a range of industrial applications, including electronics, automotive and mechanical components. Its product catalogue lists custom specifications such as the Zoom copper balls described here, but the listing does not provide further details on production capacity, certifications or client references. Prospective buyers should therefore request any additional documentation directly from the company.
Our Zoom Copper Balls, spanning 1.5mm to 20mm in diameter, are manufactured from high-purity electrolytic copper Cu 99.99% for reliable performance in electronics manufacturing. These precision copper spheres are widely used in PCB assembly, electrical contacts, conductive fillers, and welding applications, meeting rigorous industrial quality standards. Available in bulk packaging for efficient B2B supply, they are suitable for importers and distributors sourcing electronic hardware components at competitive wholesale rates.

Before placing an order, importers should request material certificates confirming the 99.99 % Cu purity and any relevant ISO test reports. Verifying the supplier’s harbor tier status and asking for recent factory audit documents can also reduce risk. Clarify the exact packaging format, such as 25 kg bulk cartons, to ensure it matches handling capabilities at the destination.
Logistics details need confirmation: ask the supplier which Incoterms (FOB, CIF, etc.) they can offer, typical lead times from the Guangdong port, and preferred payment methods such as L/C or T/T. Because the listed response rate is 0 %, establishing a clear communication channel early helps avoid delays. Confirm whether the supplier can arrange container loading or prefers smaller parcel shipments.
Quality assurance should include pre‑shipment inspection by a third‑party lab, focusing on diameter tolerance, hardness and surface roughness. Request a copy of the inspection report and any conformity certificates before cargo release. Maintaining documentation such as the Bill of Lading, commercial invoice and certificate of origin will streamline customs clearance for the copper balls.
