The harmonica-shaped tube offered by Dongyingtaixiao Trade Company is fabricated from Aluminum Alloy 3003, a medium‑strength alloy noted for corrosion resistance and formability. It measures 9 mm by 68 mm and incorporates 23 precisely drilled holes, matching the dimensions supplied in the source description. The product is marketed for integration into aluminium‑tube radiators used in automotive and HVAC heat‑exchange systems.
Alloy 3003 belongs to the 3000 series, which typically provides a tensile strength around 120 MPa and a thermal conductivity near 200 W·m⁻¹·K⁻¹, making it suitable for applications requiring efficient heat dissipation. In the tube‑fabrication industry, a dimensional tolerance of ±0.1 mm is standard for components of this size, and a milled surface finish is common to ensure smooth fluid flow. These attributes align with the typical specifications for aluminium heat‑exchanger tubes.
Primary buyers include OEM manufacturers of vehicle cooling systems and commercial HVAC equipment who need reliable, corrosion‑resistant tubing. Dongyingtaixiao lists the product as a specialised industrial component and does not disclose minimum order quantities, pricing, or lead times, so interested importers should request those details directly. Trade terms such as Incoterms, payment schedules and packaging options can be negotiated with the supplier after initial contact.
