Manufactured via cold drawing process, these tubes feature uniform wall thickness, corrosion resistance, and excellent formability, meeting the rigorous demands of high-performance systems.
Cold-Drawn Performance
Material Excellence: 3003 H14 alloy (Mg 1%, Mn 1.2%) with yield strength 140 MPa, 20% stronger than hot-extruded alternatives, compliant with ASTM B241/B241M.
Dimensional Precision: OD tolerance ±0.05mm, wall thickness tolerance ±0.03mm (ISO 2768-1 fine class), ensuring leak-free connections in high-pressure systems (max 100 bar).
Corrosion & Heat Resistance
Surface Protection: Natural aluminum oxide layer (0.1-0.2μm) provides base corrosion resistance, with optional chromate conversion coating (MIL-DTL-5541 Class 1A) for marine environments (1500h salt spray).
Thermal Conductivity: 165 W/mK heat conductivity, 30% more efficient than carbon steel, ideal for heat exchanger tubes (EN 13480-5 compliant).
Formability & Machinability
Cold Workability: Elongation ≥15% allows bending (min radius 2x OD) and flaring (30° angle) without cracking, supporting complex piping layouts.
Surface Finish: Smooth interior (Ra ≤1.6μm) reduces fluid friction (Darcy-Weisbach factor ≤0.015), improving flow efficiency in hydraulic systems.
Size & Connection Options
Range: OD 6-150mm, wall thickness 1-10mm, length 1-6m (custom lengths up to 12m available).
End Treatments: Beveled ends, threaded (NPT/BSP), and grooved (GROOVE LOK) for easy welding, brazing, or mechanical jointing.
Industrial Piping: Conveys water, oil, and gas in chemical plants, power stations, and refineries, compliant with ASME B31.3 process piping codes.
Heat Exchangers: Used in HVAC systems and automotive radiators, leveraging high thermal conductivity for efficient heat transfer (UA value improvement 25%).
Structural Framing: Lightweight supports for industrial racks, conveyor systems, and solar panel mounts, reducing overall structure weight by 40% compared to steel.
Cold Drawing Expertise
5-stage cold drawing process with intermediate annealing (350°C for 1 hour) ensures uniform grain structure, validated by metallographic analysis (ASTM E3-11).
Compliance Leadership
Certified to ISO 9001:2015, ASME BPVC Section VIII, and EN 10216-5 for pressure equipment, with material traceability (Mill Test Reports for each batch).
Cost-Effective Solutions
30% lower cost than equivalent stainless steel tubes, with 5-year corrosion warranty in standard environments (humidity ≤70% RH).
Global Certification
Export-compliant with CE PED Module B+D, UL 1068, and CNAS testing, ensuring seamless market access to Europe, North America, and APAC regions.
