Working with 8009 F-FORGED
Is 8009 easy to machine?
Machine like a high-silicon Al: PCD or fine-grain uncoated carbide, high speed, light feed and flood coolant — the Al12(Fe,V)3Si particles wear HSS quickly.
Can 8009 be welded?
Avoid fusion welding (dispersoid coarsening kills elevated-temperature strength); use friction/inertia welding, FSW, diffusion bonding or mechanical fastening.
Can 8009 be formed, bent or molded?
Produced only by rapid-solidification powder/ribbon consolidation plus hot extrusion or hot rolling; warm-form sheet at 200–350 °C, cold formability is poor.
What surface finishes work on 8009?
Anodizing gives dark, patchy films; prefer chromate-free conversion coating plus high-temperature primer, or bare use with a thin sol-gel/paint system.
8009 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

| Febound in Al12(Fe,V)3Si dispersoids | 8 – 9 | 8.5 |
| V | 1.1 – 1.5 | 1.3 |

8009 F-FORGED — frequently asked
What is 8009 F-FORGED used for?
8009 F-FORGED is typically used for aerospace elevated-temperature components, turbine engine parts and high-temperature airframe structures. In short: 315 °C service aluminum; dispersion-strengthened, not age-hardened; specialty aerospace availability.
What is the yield strength of 8009 F-FORGED?
8009 F-FORGED has a typical yield strength of 345 MPa (50 ksi) and a tensile strength of 390 MPa (56.6 ksi) — stronger than 83% of aluminum grades. Strength varies by condition: see the 3 listed tempers.
Is 8009 F-FORGED easy to machine?
Not especially — machinability is rated fair (42/100, worse than 77% of aluminum grades). Machine like a high-silicon Al: PCD or fine-grain uncoated carbide, high speed, light feed and flood coolant — the Al12(Fe,V)3Si particles wear HSS quickly.
Can 8009 F-FORGED be welded?
Not readily — weldability is rated poor (25/100). Avoid fusion welding (dispersoid coarsening kills elevated-temperature strength); use friction/inertia welding, FSW, diffusion bonding or mechanical fastening.
What surface finishes work on 8009 F-FORGED?
Anodizing gives dark, patchy films; prefer chromate-free conversion coating plus high-temperature primer, or bare use with a thin sol-gel/paint system.
Can 8009 F-FORGED be formed, bent or molded?
Produced only by rapid-solidification powder/ribbon consolidation plus hot extrusion or hot rolling; warm-form sheet at 200–350 °C, cold formability is poor.
What is the maximum service temperature of 8009 F-FORGED?
8009 F-FORGED is rated for continuous use to about 315°C (599 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 8009 F-EXT and 8009 F-HIP?
F-EXT is the default condition — standard supplied condition for bar, profile and forging stock; highest longitudinal strength. F-HIP: billet or near-net P/M preform condition; use only where subsequent hot working is not possible, as ductility is lowest. Yield strength is 385 MPa in F-EXT versus 320 MPa in F-HIP.
