A mixture of two or more metals or metalloids that are mutually soluble in the molten state; distinguished as binary, ternary, quaternary, etc., depending on the number of metals within the mixture. Alloying elements are added to alter the hardness, strength, and toughness of a metallic element, thus obtaining properties not found in a pure metal. Alloys may also be classified on the basis of their behavior when solidified.
A metallic substance (e.g., brass) resulting from the fusion or mixture of two or more metals.
A metallic compound consisting of a combination of two or more distinct metals.
