Material of alloy necklace The material of alloy necklace is a solid product with metallic characteristics, which is made by mixing and melting one metal with another, or several metals or nonmetals, and cooling and solidifying. Alloy materials can be divided into binary alloys, ternary alloys and multicomponent alloys according to the number of their constituent elements.
Alloys can be said to be macro-homogeneous chemicals containing metal elements. Because of the complex composition, any element can be used as an alloying element, but a large number of elements added are still metals. Therefore, in the solid state, the alloy may be a single-phase or multi-phase mixture, or a crystalline, quasicrystalline and amorphous mixture.
Common alloys in people's daily life are stainless steel, brass, bronze, white copper, 18K gold and other materials, among which 18K gold, brass and white copper are the most commonly used in jewelry design, mainly used for various jewelry inlays, such as diamonds, rubies and pearls.
