Scandium is a silvery-white metal with a metallic luster, similar in appearance to other transition metals. It has a bright, shiny surface and reflects light well, giving it a characteristic metallic sheen. Scandium's appearance is quite typical for metals and doesn't have any particularly distinctive visual features.

Aluminium–scandium alloys (AlSc) are aluminum alloys that consist largely of aluminium (Al) and traces of scandium (Sc) as the main alloying elements. In principle, aluminium alloys strengthened with additions of scandium are very similar to traditional nickel-base superalloys in that both are strengthened by coherent, coarsening resistant precipitates
