Crafted via cold extrusion, these tubes feature uniform wall thickness, high fatigue resistance, and customizable finishes, ideal for machinery, automotive components, and construction frameworks.
Mechanical Performance
Alloy Excellence: 6060 T5 (Mg 0.6%, Si 0.4%) with yield strength 190 MPa and elongation 12%, surpassing 6063-T5 by 15% in tensile strength (ASTM B221 compliant).
Dimensional Precision: OD tolerance ±0.05mm, wall thickness ±0.03mm (ISO 2768-1 fine class), ensuring seamless fit with bearings, flanges, and fasteners (e.g., ISO 7-1 NPT threads).
Extrusion & Surface Treatment
Cold Extrusion: Produces grain flow alignment (elongation ≥15%) for improved fatigue life (10^7 cycles at 80 MPa), 20% better than hot-extruded tubes.
Finish Options:
Anodised (15μm Type II) for cosmetic protection (salt spray 500h).
Chromate conversion (MIL-DTL-5541 Class 1A) for marine applications (1500h salt spray).
Size & Load Capacity
Range: OD 10-200mm, wall thickness 1-10mm, length 1-12m (custom cut to ±1mm), supporting axial loads up to 50kN (calculated per EN 1999-1-1).
Weight Advantage: 60% lighter than steel tubes (density 2.7g/cm³), reducing transportation costs and structural load in mobile equipment.
Formability & Machinability
Bending/Riveting: Minimum bend radius 2x OD without cracking, compatible with CNC machining (drilling, tapping, threading) for complex assemblies.
Industrial Machinery: Structural supports for conveyor systems, robotic arms, and hydraulic cylinders, compliant with ISO 10133 mechanical stability standards.
Automotive Components: Lightweight tubular frames for EV battery supports and suspension parts, reducing vehicle weight by 20% (UN R100 compliant).
Construction: Scaffolding poles, ladder rails, and temporary structures, with anodised finishes resisting construction site corrosion (e.g., cement dust, moisture).
Extrusion Technology Leadership
1000-ton extrusion presses with temperature-controlled dies (±5°C) ensure uniform grain structure, validated by metallographic analysis (ASTM E3-11).
Certification & Compliance
Certified to EN 10219-1 for structural hollow sections and IATF 16949 for automotive applications, with material traceability from billet to finished tube.
Custom Fabrication
In-house CNC turning/milling for precision ends (chamfering, flaring) and surface texturing (knurling, grooving), supporting JIT inventory models.
Global Engineering Support
Dedicated team for FEA analysis (stress/strain simulation) and DFMA suggestions, optimizing tube dimensions for cost and performance.
