6092/SiC/17.5p O vs 6092/SiC/17.5p T4
Composite · 6092/SiC/17.5p grade comparison
6092/SiC/17.5p O and 6092/SiC/17.5p T4 are two grades of the same composite grade, 6092/SiC/17.5p: O (annealed) versus T4 (solution heat treated and naturally aged). The chemistry is identical, so every difference below comes from the condition. 6092/SiC/17.5p T4 is the stronger of the two: yield strength 260 MPa (37.7 ksi) against 150 MPa (21.8 ksi) for 6092/SiC/17.5p O, about 73% more; tensile strength follows at 400 MPa (58 ksi) vs 250 MPa (36.3 ksi). In exchange, 6092/SiC/17.5p O is the more ductile: elongation 12% versus 9% for 6092/SiC/17.5p T4. 6092/SiC/17.5p O runs hotter in service (200°C vs 120°C continuous) and 6092/SiC/17.5p O conducts heat better (175 W/m·K vs 150 W/m·K).
6092/SiC/17.5p OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
6092/SiC/17.5p T4Choose it when strength drives the design.
6092/SiC/17.5p O vs 6092/SiC/17.5p T4: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all composite grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

6092/SiC/17.5p O vs 6092/SiC/17.5p T4 — frequently asked
Is 6092/SiC/17.5p T4 stronger than 6092/SiC/17.5p O?
Yes. 6092/SiC/17.5p T4 has a typical yield strength of 260 MPa (37.7 ksi) against 150 MPa (21.8 ksi) for 6092/SiC/17.5p O — about 73% more. Tensile strength is 400 MPa (58 ksi) vs 250 MPa (36.3 ksi).
Which grade does FabDigit quote by default, O or T4?
T6 is the default 6092/SiC/17.5p condition in the FabDigit quote flow (neither O nor T4). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, 6092/SiC/17.5p O or 6092/SiC/17.5p T4?
6092/SiC/17.5p O, by a small margin. Both rate poor for machinability — 28/100 against 20/100 for 6092/SiC/17.5p T4.
