Alloy jewelry is formed by uniform fusion and cooling of two or more metals, and then cooled and solidified. According to the number of constituent metals, it can be divided into binary alloys, ternary alloys and multi-element alloys. Alloy jewelry has strong plasticity and variability, and can be made arbitrarily, but alloy jewelry is not suitable for people with allergies and is prone to allergic symptoms. Alloys are not mixtures in the general concept, and can even be pure substances, such as single-phase intermetallic alloys. The physical properties of alloys, such as density, reactivity, Young's modulus, electrical conductivity, and thermal conductivity may be similar to those of the constituent elements of the alloy, but the tensile and shear strengths of alloys are generally related to the properties of the constituent elements. with large differences.

It is generally harmless to wear alloy jewelry normally, but if you do not pay attention to hygiene and wear it for a long time, it will induce "jewelry disease". Most of the alloy jewelry are electroplated products. Mildew will occur, which is quite harmful to the human body. Alloy jewelry does not need special maintenance or cleaning with a high-end cleaning machine. Just remember to keep the alloy jewelry away from acidic and alkaline substances as much as possible. Alloy jewelry is easy to be scratched by collision. Be careful when storing. Do not overlap the jewelry. It should be stored in the original packaging bag or in a jewelry box with a separate small lattice to avoid rubbing each other and scratching the surface.
