If that’s the case, why is e.g. 10% of a 787 still using steel rather than titanium, which can be had at 11$ per kg?

- elil17 4y agoThe challenge is with design, certification, and manufacturing (forming and joining), not with affording the material. Plus, high strength steels can bear more stress than titanium, although they weigh more. This may be needed for certain space-constrained components.
