2124/SiC/25p vs Glidcop AL-15
Composite · grade comparison
2124/SiC/25p and Glidcop AL-15 are both composite grades. 2124/SiC/25p is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 331 MPa (48 ksi) for Glidcop AL-15, about 45% more; tensile strength follows at 620 MPa (89.9 ksi) vs 413 MPa (59.9 ksi). In exchange, Glidcop AL-15 is the more ductile: elongation 18% versus 3% for 2124/SiC/25p. 2124/SiC/25p is lighter (2.88 g/cm³ vs 8.9 g/cm³ for Glidcop AL-15) and Glidcop AL-15 is stiffer (130 GPa vs 114 GPa). On the shop floor, Glidcop AL-15 machines more easily (fair vs not recommended).
2124/SiC/25pChoose it when strength drives the design, or when weight is the constraint.
Glidcop AL-15Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
2124/SiC/25p vs Glidcop AL-15: 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.
