The Harmonica Shape Aluminum Tube is manufactured from Aluminum Alloy 3003 and features a non‑circular cross‑section measuring 8 mm by 30 mm with three evenly spaced holes. This geometry is intended for use in heat‑exchanger and radiator applications where enhanced fluid flow and thermal conductivity are required. The tube is supplied in a seamless form, providing a consistent internal surface that reduces turbulence and improves heat transfer efficiency. The supplier highlights high strength, corrosion resistance and good thermal performance as key advantages for large radiators.
Aluminum 3003 is a standard alloy in the HVAC and cooling‑system industries, offering a typical tensile strength of around 120 MPa and excellent workability. Dimensional tolerances for such tubes are generally ±0.1 mm, and a surface finish of Ra 1.6 µm is common to minimise fouling. Typical tube lengths are 6 m, which can be cut to size on demand, and the weight is approximately 0.15 kg per metre. These attributes align with industry expectations for medium‑strength structural components in cooling equipment.
Potential buyers include OEM manufacturers of radiators, heat exchangers and other HVAC equipment who need reliable, standardized tube profiles. While the listing does not disclose specific MOQ or price, Dongyingtaixiao Trade Company offers flexible order quantities and protective packaging for bulk shipments. Shipping terms such as FOB or CIF and payment options like L/C can be negotiated directly with the supplier after confirming the technical specifications.

When considering a purchase, first verify the alloy grade, cross‑section dimensions, hole configuration and any surface‑finish requirements. Ask the supplier for a mill test report and, if needed, a certification of corrosion resistance to match your project specifications. Confirm the minimum order quantity and packaging style to ensure it aligns with your shipping and storage plans.
Discuss logistics early by agreeing on an Incoterm such as FOB or CIF, and clarify the expected lead time for production and shipment. Because the supplier’s response rate is shown as 0.00, establish a reliable point of contact and obtain written confirmation of payment terms, whether L/C, T/T or another method. Verify that all trade documents, including commercial invoice and packing list, will be provided.
Plan for quality assurance by arranging a third‑party inspection at the factory or at the loading port. The inspection should cover dimensional checks, surface‑finish verification and material‑grade confirmation. Request the inspection report and any relevant certificates before the goods are released for export.
