Cuerterium

An extremely strong amalgam of iron, cuerterin, and a few other minor additives. Cuerterin is utilized in lieu of carbon, which is instead employed by fabricators in other more vital applications. While cuerterium is slightly heavier than ferric steel, it tends to have a higher resistance to stress load than its relative, and performs admirably when used as the chassis for heavy-duty vehicles and aerospace craft.

CDMC utilized cuerterium for the spines and spars of several high-performance aerospace craft, knowing that they needed something to retain high stress and deformation loads.
