Explore our premium architectural and specialized industrial aluminum extrusions engineered for high endurance and strict tolerance specifications.
Aluminum tube extrusions represent one of the most versatile structural elements used in modern engineering. From structural pillars and custom fluid conduit networks to lightweight frames for industrial automation, the geometry, alloy choice, and heat treatment tempers determine the integrity of the finished profile. As a leading manufacturer based in Sihui, Guangdong, Aoli Aluminum offers precision round, square, rectangular, and custom-shaped hollow profiles designed to meet international standards (including ASTM, EN, and GB specifications).
For industrial applications, understanding the difference between structural (die-line) and seamless aluminum tubes is critical. Structural tubes are typically produced using a bridge or porthole die, where the metal separates and re-welds under intense heat and pressure as it passes through the tooling. This is highly cost-effective and perfectly suited for structural building applications, window framing, and decorative projects. Seamless tubes, conversely, are extruded over a mandrel or solid piercer, eliminating weld seams entirely. These are ideal for high-pressure fluid systems, safety-critical aerospace elements, and precise CNC machining applications.
Sourcing aluminum tube extrusions from China—specifically from the cluster around Sihui and Foshan—offers key logistical and technical benefits. Our raw materials are acquired through integrated supply networks, allowing us to insulate clients from extreme spot price volatility. By managing everything from custom tool design and alloy mixing to automated extrusion, precise surface finishing, and CNC post-processing under a unified ISO quality control system, we minimize operational waste and deliver direct-to-manufacturer pricing that matches your strategic target budgets.
| Alloy Family | Typical Temper | Yield Strength (MPa) | Key Applications | Machinability |
|---|---|---|---|---|
| 6063 | T5 / T6 | 145 - 214 | Window frames, solar framing, curtain walls, lighting fixtures | Excellent |
| 6061 | T6 | 240 - 276 | Heavy-duty structural frames, CNC machined parts, marine fittings | Very Good |
| 6082 | T6 | 250 - 310 | Bridges, cranes, roof trusses, transport applications | Good |
| 6005A | T6 | 200 - 220 | Railway carriages, structural hollow profiles, complex tooling | Good |
Thermal processing is critical to unlocking the target mechanical properties of 6000-series aluminum. The T5 temper involves cooling the extruded profiles directly from the press, followed by artificial aging to stabilize the hardness. The T6 temper is more intensive, requiring solution heat treatment, rapid quenching in water or air, and artificial aging to maximize yield and tensile strength. Our facility houses specialized vertical quench systems and automated aging ovens to ensure that every production lot achieves structural compliance.
