6061/SiC/10p vs P100Gr/6061Al
Composite · grade comparison
6061/SiC/10p and P100Gr/6061Al are both composite grades. P100Gr/6061Al is the stronger of the two: tensile strength 620 MPa (89.9 ksi) against 338 MPa (49 ksi) for 6061/SiC/10p, about 83% more. In exchange, 6061/SiC/10p is the more ductile: elongation 6% versus 0.3% for P100Gr/6061Al. P100Gr/6061Al is lighter (2.5 g/cm³ vs 2.75 g/cm³ for 6061/SiC/10p) and P100Gr/6061Al is stiffer (320 GPa vs 81 GPa). On the shop floor, 6061/SiC/10p machines more easily (poor vs not recommended).
6061/SiC/10pChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
P100Gr/6061AlChoose it when strength drives the design, or when weight is the constraint.
6061/SiC/10p vs P100Gr/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.

6061/SiC/10p vs P100Gr/6061Al — frequently asked
Is P100Gr/6061Al stronger than 6061/SiC/10p?
Yes. P100Gr/6061Al has a typical tensile strength of 620 MPa (89.9 ksi) against 338 MPa (49 ksi) for 6061/SiC/10p — about 83% more.
Which is cheaper, 6061/SiC/10p or P100Gr/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, 6061/SiC/10p or P100Gr/6061Al?
6061/SiC/10p. Its machinability rates poor (30/100) against not recommended (12/100) for P100Gr/6061Al.
