The relative likeness between scandium and yttrium seems to extend to the respective metallic alloys. Thus, metallic alloys of rare-earths are similar to scandium ones, whose applications are limited to the metallurgical industry.

In a general way, scandium does not tend to form alloys with alkaline metals. However, this element is sufficiently soluble in magnesium for hardening it. There is also evidence that the scandium can be dissolved in titanium at high temperatures.
