What is 8009/SiC?
8009/SiC is a rapidly solidified Al-Fe-V-Si alloy powder, strengthened by Al12(Fe,V)3Si dispersoids and consolidated with SiC reinforcement (11p, 15p, 20p and 15w variants, plus HIP, sheet and forged forms). It is used for elevated-temperature aerospace hardware, with 425 MPa yield, 500 MPa tensile, 150 HB, 100 GPa modulus and a 315 °C maximum service temperature at 2.95 g/cm³ density. Elongation is 5 %, thermal conductivity 125 W/m·K, and fusion welding is not viable. Titanium alloys are the usual alternative above this temperature range. 8009/SiC has a density of 2.95 g/cm³ (0.107 lb/in³), heavier than 99% of aluminum grades. It melts at 640°C (1,184 °F). 8009/SiC has a yield strength of 425 MPa (61.6 ksi) and a tensile strength of 500 MPa (72.5 ksi) — stronger than 90% of aluminum grades. Elongation at break is 5% and the elastic modulus is 100 GPa (14.5 Msi).

Working with 8009/SiC
Is 8009/SiC easy to machine?
Use PCD or CVD-diamond tooling with high speed / light feed and flood coolant; carbide wears out in minutes and grinding needs diamond wheels.
Can 8009/SiC be welded?
Avoid fusion welding — melting coarsens the Al12(Fe,V)3Si dispersoids and forms Al4C3 at SiC interfaces; use friction stir, inertia friction, diffusion bonding or mechanical fastening.
Can 8009/SiC be formed, bent or molded?
Formed only by hot extrusion, isothermal forging or warm rolling at roughly 400–480 °C; cold forming is limited to very gentle radii due to low RT ductility.

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.

What surface finishes work on 8009/SiC?
Conversion coat plus primer for corrosion protection; anodising gives a grey, particle-disturbed film, and electroless nickel is a better choice for wear or solderable surfaces.

8009/SiC — frequently asked
What is 8009/SiC used for?
8009/SiC is typically used for gas turbine components, high-temperature aerospace brackets and engine casings. In short: 315 °C aluminum composite; dispersoid-strengthened rapid-solidification alloy; titanium replacement candidate.
What is the yield strength of 8009/SiC?
8009/SiC has a typical yield strength of 425 MPa (61.6 ksi) and a tensile strength of 500 MPa (72.5 ksi) — stronger than 90% of aluminum grades. Strength varies by condition: see the 7 listed tempers.
Is 8009/SiC easy to machine?
Not especially — machinability is rated poor (18/100, worse than 99% of aluminum grades). Use PCD or CVD-diamond tooling with high speed / light feed and flood coolant; carbide wears out in minutes and grinding needs diamond wheels.
Can 8009/SiC be welded?
Not readily — weldability is rated not recommended (12/100). Avoid fusion welding — melting coarsens the Al12(Fe,V)3Si dispersoids and forms Al4C3 at SiC interfaces; use friction stir, inertia friction, diffusion bonding or mechanical fastening.
What surface finishes work on 8009/SiC?
Conversion coat plus primer for corrosion protection; anodising gives a grey, particle-disturbed film, and electroless nickel is a better choice for wear or solderable surfaces.
Can 8009/SiC be formed, bent or molded?
Formed only by hot extrusion, isothermal forging or warm rolling at roughly 400–480 °C; cold forming is limited to very gentle radii due to low RT ductility.
What is the maximum service temperature of 8009/SiC?
8009/SiC 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/SiC SiC/11p-F and 8009/SiC HIP-F?
SiC/11p-F is the default condition — baseline extruded bar/section: best balance of strength, ductility and toughness for 315 °C service parts. HIP-F: isotropic consolidated billet for subsequent forging or machining of near-net blocks; properties below worked product. Yield strength is 425 MPa in SiC/11p-F versus 385 MPa in HIP-F.
How much does 8009/SiC cost?
8009/SiC is a high-cost aluminum ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
