W: I heard that the earrings produced will be made of different materials, but after electroplating, I can't distinguish them. I don't know which material is the best. D: No matter what color the earrings are electroplated, in fact, earring manufacturers have a way to distinguish the material. Different styles and different grades will use different materials. Generally, the materials used are alloy, copper, resin, stainless steel, silver, etc. If it is divided only from the material, then the alloy is the cheapest, and the value of silver is the highest, but in terms of wearing time, the color retention period of stainless steel earrings after the vacuum plating process in the furnace is the longest. In fact, in addition to the material, the workmanship is also very important. Only by finding a good earring manufacturer, using good materials and finer workmanship, the earrings produced in this way will have a texture. The higher-grade earrings will be more popular.
