6092/SiC/17.5p vs B/6061Al
Composite · grade comparison
6092/SiC/17.5p and B/6061Al are both composite grades. B/6061Al is the stronger of the two: yield strength 950 MPa (138 ksi) against 434 MPa (62.9 ksi) for 6092/SiC/17.5p, about 119% more; tensile strength follows at 1,380 MPa (200 ksi) vs 483 MPa (70.1 ksi). In exchange, 6092/SiC/17.5p is the more ductile: elongation 6% versus 0.75% for B/6061Al. B/6061Al is lighter (2.65 g/cm³ vs 2.8 g/cm³ for 6092/SiC/17.5p) and B/6061Al is stiffer (210 GPa vs 100 GPa). On the shop floor, 6092/SiC/17.5p machines more easily (poor vs not recommended).
6092/SiC/17.5pChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
B/6061AlChoose it when strength drives the design, or when weight is the constraint.
6092/SiC/17.5p vs B/6061Al: 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 vs B/6061Al — frequently asked
Is B/6061Al stronger than 6092/SiC/17.5p?
Yes. B/6061Al has a typical yield strength of 950 MPa (138 ksi) against 434 MPa (62.9 ksi) for 6092/SiC/17.5p — about 119% more. Tensile strength is 1,380 MPa (200 ksi) vs 483 MPa (70.1 ksi).
Which is cheaper, 6092/SiC/17.5p or B/6061Al?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, 6092/SiC/17.5p or B/6061Al?
6092/SiC/17.5p. Its machinability rates poor (22/100) against not recommended (8/100) for B/6061Al.
