Drawn Aluminum Tube

Drawn aluminum tube refers to aluminum tubing that is cold-worked through multiple-pass drawing after initial extrusion. Compared to extruded tubes, drawn tubes offer superior dimensional accuracy (up to ±0.05 mm), smoother surface finish (Ra ≤ 1.6 μm), and enhanced concentricity and mechanical performance.

Chalco offers a full range of cold drawn, seamless drawn,precision drawn aluminum tubes—from aerospace-grade ±0.05 mm precision tubes to cost-effective long-length tubing for heat exchangers and structural systems.

FAQs

Is a cold drawn aluminum tube suitable for high-precision bearing or hydraulic use?

Yes. Cold drawing delivers tight dimensional control and improved roundness/concentricity. Typical tolerances reach ±0.05 mm (up to ±0.02 mm on request) with optional surface roughness down to Ra ≤ 0.8 μm, making it a good fit for precision fits, pneumatic and hydraulic systems.

Cold drawn vs. precision drawn — which should I choose?

Precision drawn tubes are cold drawn and then further straightened and finished for even tighter tolerances and a finer surface. Choose precision drawn when you need the smallest tolerances and best finish for high-end assemblies; choose cold drawn when you need high accuracy with better cost efficiency for structural or pressure-line use.

Can you manufacture to my drawing and deliver ready-to-assemble parts?

Yes. We customize OD, wall, length, temper, and tolerances to your drawing and provide value-added operations such as cutting, drilling, threading, bending, CNC machining, and welding—so tubes arrive ready for direct assembly.

Will these tubes withstand outdoor or corrosive environments?

Yes. We offer surface finishes such as anodizing (typical film 8–12 μm), powder coating, and e-coat to boost corrosion resistance and appearance for coastal, chemical, or outdoor use.

What is the typical lead time?

Standard sizes ship in about 7–10 days. Custom sizes usually deliver in 2–4 weeks depending on quantity and processing; expedited production is available.

How are the tubes packed and protected for shipment?

Packed with moisture-proof film and rigid protection, fixed in wooden crates with anti-corrosion covering, compliant with ASTM B241. Optional single-tube sleeves or separators ensure the tubes are ready to use on arrival.
