Hoʻohana ʻia ʻo Scandium Metal i ka uhi optical, catalyst, electronic ceramics a me ka ʻoihana laser. ʻO ka noi nui o Scandium ma ke kaumaha i loko o nā alloys Aluminium-Scandium no nā ʻāpana ʻoihana aerospace liʻiliʻi. ʻO kekahi mau mea o nā mea haʻuki, e hilinaʻi nei i nā mea hana kiʻekiʻe, ua hana ʻia me nā alloys Scandium-Aluminium. Hoʻohana ʻia i loko o ka hoʻohui ʻana o nā pūʻulu maʻamau, Sc19Br28Z4, (Z=Mn, Fe, Ru a i ʻole Os). He mea hoihoi kēia mau puʻupuʻu no ko lākou kūkulu ʻana a me nā waiwai magnetic. Hoʻohana ʻia ia e hana i ka super alloy.
