Frequently Asked Questions

What is the primary function of an intercooler tube in a vehicle?

The intercooler tube is part of the turbocharging system. Its main purpose is to cool the compressed air from the turbocharger before it enters the engine, thereby increasing air density and improving engine ventilation efficiency.

Which aluminum alloys are used for these rectangular tubes?

The core layer typically uses 3003 or 3005 series aluminum, while the cladding layer uses 4045, 4343, or 7072 alloys to provide superior corrosion resistance and welding properties.

What are the advantages of high-frequency welding for intercooler pipes?

High-frequency welding ensures a strong, clean seam with very low weld line height (≤0.08mm). It allows for high production speeds while maintaining strict dimensional tolerances.

Are the tube dimensions customizable?

Yes, both the length and specific dimensions of the rectangular tubes can be customized according to specific customer requirements and engine designs.

How do you ensure the surface quality of the tubes?

The manufacturing process includes strict inspections to ensure surfaces are free of oil, dust, and aluminum chips. We also guarantee no pressure pits, bumps, or scratches are present on the final product.

What certifications do these aluminum products carry?

Our products meet international standards including CE, ISO 9001:2008, and SGS certifications, and are fully compliant with ROHS environmental standards.
