This harmonica-shaped tube is extruded from Aluminum 3003 (Al-Mn Alloy) and features a 1 mm x 8 mm profile with a 4-hole fluted design to maximise heat dissipation surface area. The tube is engineered for automotive and industrial radiator applications, where thermal conductivity and corrosion resistance are critical for performance and longevity.
Aluminum 3003 is a standard grade for heat exchange applications due to its excellent thermal conductivity of approximately 167 W/m·K and moderate strength, which balances formability and durability. The typical wall thickness for such tubes ranges from 0.35 mm to 4.00 mm, with the 4-hole design enhancing structural integrity and heat transfer efficiency.
OEM radiator manufacturers and aftermarket suppliers use these tubes in cooling systems for passenger vehicles, commercial trucks, and industrial machinery. Buyers should confirm the exact dimensions, hole configurations, and thermal performance requirements with Dongying Taixiao Trade Company to ensure compatibility with their radiator assemblies.

Before ordering, verify the exact alloy grade, dimensions, and hole configurations with Dongying Taixiao Trade Company to ensure the tubes match your radiator’s thermal and structural requirements. Request samples to test fit, heat dissipation, and pressure resistance in your specific application.
Confirm the supplier’s lead times, as custom orders may require additional production time. Discuss incoterms such as FOB or CIF, as well as packaging methods, to ensure the tubes arrive in optimal condition. Buyers should also clarify payment terms and any applicable certifications for their market.
Inspect the tubes upon delivery for dimensional accuracy, surface quality, and freedom from defects. Request material certificates and test reports to validate the alloy composition and thermal properties. For critical applications, consider third-party inspections to confirm compliance with your radiator’s performance standards.
