At room temperature, LaNi5-based multicomponent alloys can easily react with Cu2+ aqueous solution (such as the CuSO4 solution). The elements La, Ni, Co, Mn and Al in the alloys were oxidized to form their ions correspondingly, and the Cu2+ ion was reduced to precipitate as metal copper.

Key words: LaNi5-based alloy, Redox reaction
