2124/SiC/25p vs N-1
Composite · grade comparison
2124/SiC/25p and N-1 are both composite grades. 2124/SiC/25p is the stronger of the two: tensile strength 620 MPa (89.9 ksi) against 80 MPa (11.6 ksi) for N-1, about 7.8 times as much. N-1 is lighter (1.15 g/cm³ vs 2.88 g/cm³ for 2124/SiC/25p) and 2124/SiC/25p is stiffer (114 GPa vs 5.5 GPa). On the shop floor, N-1 machines more easily (good vs not recommended).
2124/SiC/25pChoose it when strength drives the design, or when the part sees heat.
N-1Choose it when weight is the constraint, or when the part is machined in volume.
2124/SiC/25p vs N-1: 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.

2124/SiC/25p vs N-1 — frequently asked
Is 2124/SiC/25p stronger than N-1?
Yes. 2124/SiC/25p has a typical tensile strength of 620 MPa (89.9 ksi) against 80 MPa (11.6 ksi) for N-1 — about 7.8 times as much.
Which is cheaper, 2124/SiC/25p or N-1?
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, 2124/SiC/25p or N-1?
N-1. Its machinability rates good (60/100) against not recommended (12/100) for 2124/SiC/25p.
