The term strategic and critical raw materials is relative to their importance for major importing countries because what is critical to one country may not be critical for another. Moreover, the list of these raw materials is not static.Copper, iron, manganese, nickel, cobalt, chromium, etc., increase it, as is to be expected, and so do magnesium and rare earths. Fatigue resistance is relatively low, especially if the silicon is not modified or is spheroidised by heat treatment. Cobalt and manganese may improve the fatigue resistance.
