The harmonica‑shaped tube for automobile is an aluminium radiator insert sized at 8 mm × 30 mm and incorporates three precision‑drilled holes. It is produced from aluminium alloy 3003 (Al‑Mn series with Mn 1.0‑1.5 %) as indicated by the supplier. The tube’s wall thickness is specified between 0.35 mm and 4.00 mm, while its overall width and height fall within 8 mm - 99 mm and 2 mm - 10 mm respectively. These measurements align with the dimensional standards for compact heat‑exchanger cores.
Alloy 3003 delivers a typical elongation of about 12 % and a typical corrosion resistance that meets automotive environmental requirements. The harmonica profile increases the effective heat‑transfer area, a design choice common in high‑capacity radiators for large vehicles. Typical surface roughness for mill‑finished aluminium of this grade is Ra ≤ 1.6 µm, facilitating efficient coolant flow. Compared with straight‑tube designs, the wavy geometry reduces flow resistance and improves thermal uniformity.
Vehicle manufacturers, parts integrators and large‑scale service centres source this component for new‑car radiator assemblies and for retrofit kits. The supplier lists the item under aluminium tube radiator parts and notes that bulk orders are handled, but exact MOQ and lead time must be confirmed directly. Prospective buyers should request material certification, dimensional tolerance sheets and agreed Incoterms before confirming the purchase.

Prior to ordering, confirm the exact aluminium grade, wall‑thickness selection and hole tolerance against the supplier’s technical drawing. Request a material test report and dimensional inspection certificate to ensure the tube meets the required radiator specifications. Verify whether any surface‑treatment documentation, such as anodising process records, is available if that finish is required.
Shipping aluminium radiator components from China generally uses sea freight under Incoterms like FOB or CIF. Because the listing does not state lead‑time or payment conditions, ask the supplier to specify expected production lead‑time, shipping schedule and preferred payment method, whether it be T/T, L/C or another arrangement. Clarify packaging details, such as bulk bundling or protective wrapping, to prevent damage during transport.
For quality assurance, arrange visual inspection for surface defects, dimensional verification using calibrated gauges, and functional testing of thermal performance under simulated coolant flow. If needed, engage a third‑party inspection agency and request the inspection report before shipment. Ensure the supplier provides a Certificate of Conformity and any applicable export compliance documents for China.
