P100Gr/6061Al T6 vs P100Gr/6061Al UD45-F

Composite · P100Gr/6061Al grade comparison

P100Gr/6061Al T6 and P100Gr/6061Al UD45-F are two grades of the same composite grade, P100Gr/6061Al: T6 (solution heat treated and artificially aged) versus UD45-F (UD Vf≈45%). The chemistry is identical, so every difference below comes from the condition. P100Gr/6061Al T6 is the stronger of the two: tensile strength 660 MPa (95.7 ksi) against 620 MPa (89.9 ksi) for P100Gr/6061Al UD45-F, about 6% more. In exchange, P100Gr/6061Al UD45-F is the more ductile: elongation 0.3% versus 0.25% for P100Gr/6061Al T6. P100Gr/6061Al UD45-F runs hotter in service (350°C vs 250°C continuous).

P100Gr/6061Al T6Choose it when strength drives the design.

P100Gr/6061Al UD45-FChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
