6061/SiC/10p vs MA754
Composite · grade comparison
6061/SiC/10p and MA754 are both composite grades. MA754 is the stronger of the two: yield strength 585 MPa (84.8 ksi) against 296 MPa (42.9 ksi) for 6061/SiC/10p, about 98% more; tensile strength follows at 965 MPa (140 ksi) vs 338 MPa (49 ksi). MA754 is the more ductile: elongation 21% versus 6% for 6061/SiC/10p. 6061/SiC/10p is lighter (2.75 g/cm³ vs 8.3 g/cm³ for MA754) and MA754 is stiffer (149 GPa vs 81 GPa). On the shop floor, 6061/SiC/10p machines more easily (poor vs not recommended).
6061/SiC/10pChoose it when weight is the constraint, or when the part is machined in volume.
MA754Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
6061/SiC/10p vs MA754: 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 MA754 — frequently asked
Is MA754 stronger than 6061/SiC/10p?
Yes. MA754 has a typical yield strength of 585 MPa (84.8 ksi) against 296 MPa (42.9 ksi) for 6061/SiC/10p — about 98% more. Tensile strength is 965 MPa (140 ksi) vs 338 MPa (49 ksi).
Which is cheaper, 6061/SiC/10p or MA754?
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 MA754?
6061/SiC/10p. Its machinability rates poor (30/100) against not recommended (12/100) for MA754.
