Primary FD Materials Alloy Elastic Modulus Elastic Limit Market-Approved FD Examples Cobalt-nickel-chromium ∼120–240 GPaa ∼ 0.5 to 1.5%a PED, PED Flex, PED Shield, PED Vantage, Surpass Streamline (Stryker), Surpass Evolve2 Nitinol ∼ 40–10 GPaa ∼ 6%–12%a FRED, FRED Jr, FRED X, Silk, Silk+, p64, Tubridge2
↵a Use due consideration in applying values for modeling because the Young modulus and elastic limit (pseudoelastic for nitinol) can vary widely due to process-structure texture and strength outcomes. Bookends given here are realistic possible outcomes dependent on the supplier production path and target outcomes.
