Shelf life: Indefinite under dry, covered storage; no degradation of mechanical properties
2. Core Industrial Applications
-
Building & construction: Window frames, curtain walls, railings, and solar panel frames – outperforms 6060 in anodizing uniformity and post-extrusion straightness
-
Automotive & transportation: Roof rails, heat sinks for EV battery cooling, hydraulic tubes – reduces secondary machining due to tight dimensional consistency
-
Consumer & industrial electronics: LED heat sinks, enclosures, telescopic poles – superior thermal conductivity (≈200 W/m·K) ensures longer component life
-
Furniture & medical equipment: Lightweight structural profiles – lower die wear vs. 6061 reduces tooling cost per ton by 12–18%
3. Competitive Advantages
-
Quality consistency: <1% RSD across tensile strength (min 185 MPa) and elongation (min 8%) per heat lot; 100% eddy current tested for seam defects
