Kr is a transition metal with moderate elastic stiffness and density, positioned in the middle range of structural metals. It is primarily used in specialized aerospace, automotive, and high-strength structural applications where a balance between weight and rigidity is required, as well as in chemical processing equipment and corrosion-resistant components. Engineers select this material when performance envelopes demand intermediate strength-to-weight ratios or when corrosion resistance and thermal stability are critical factors over materials that are either too heavy or lack sufficient stiffness.
