6092/SiC/17.5p T4 vs 6092/SiC/17.5p T651

Composite · 6092/SiC/17.5p grade comparison

6092/SiC/17.5p T4 and 6092/SiC/17.5p T651 are two grades of the same composite grade, 6092/SiC/17.5p: T4 (solution heat treated and naturally aged) versus T651 (T6, stress relieved by stretching). The chemistry is identical, so every difference below comes from the condition. 6092/SiC/17.5p T651 is the stronger of the two: yield strength 427 MPa (61.9 ksi) against 260 MPa (37.7 ksi) for 6092/SiC/17.5p T4, about 64% more; tensile strength follows at 476 MPa (69 ksi) vs 400 MPa (58 ksi). In exchange, 6092/SiC/17.5p T4 is the more ductile: elongation 9% versus 6% for 6092/SiC/17.5p T651. 6092/SiC/17.5p T651 runs hotter in service (150°C vs 120°C continuous).

6092/SiC/17.5p T4Choose it when the part is bent, formed or impact-loaded.

6092/SiC/17.5p T651Choose it when strength drives the design, or when the part sees heat.
