Gold filled 2: Pasting gold is a craft with a long history. It is satisfied that the thickness of pure gold is not less than 0.5μm, so the common gold-clad coating (alloy) on the market is thicker than the gold-plated coating (alloy). It must meet the above-mentioned requirement that the gold content of the gold-clad covering layer is not less than 37.5‰ and the gold content of the gold-plated covering layer is not less than 58.5‰. However, the common covering layer on the market is generally not pure gold.
In the domestic standard, the pure gold thickness of the gold-clad and gold-plated covering layer is the same, and the thickness is not less than 0.5μm to meet the standard. The thickness of the covering layer (alloy) is different The purity of the covering layer is differentĪccording to domestic standards, the gold content of the gold-clad covering layer is not less than 37.5‰, and the gold content of the gold-plated covering layer is not less than 58.5‰.Ġ3. The Gold filled adopts mechanical processing methods, and the gold-plated adopts processing methods such as electroplating or electroless plating.Ġ2. The difference between Gold filled and gold-plated Gold-plating treatment (such as silver-copper gold-plating) can improve the color of the material, thereby improving the viewing effect of the article. Gold-plating is divided into two categories: one is gold-plating of homogenous materials, and the surface of gold jewelry is gold-plated to improve the brightness and color of the jewelry the other is gold-plating of heterogeneous materials: the surface of non-gold materials is gold-plated. Gold plating uses methods such as electroplating or electroless plating to plate a layer of gold on the base metal, but the plating layer is generally relatively thin. It should be noted that the gold-plated coating with a thickness of 0.05μm-0.5μm is defined as "thin gold-plated coating" in the national standard The domestic standard QB/T 1131-2005 "Regulations on the Thickness of Jewelry Gold Covering Layer" defines the "gold-plated cover layer" as follows: "The gold cover layer obtained by electroplating or electroless plating is called the gold-plated cover layer." It is required that "the thickness of the gold covering layer is not less than 0.5μm (micrometer)". Gold-plated, the English name is Gold-Plated.
Gold-filled jewelry has the luster and texture of gold jewelry, as well as higher wear resistance and oxidation resistance. The surface of these materials is wrapped with a layer of gold or K gold, and the inner The material is wrapped up. The inner material is not precious metals such as gold and platinum, but some alloy materials such as aluminum, copper, zinc, etc. Gold coating is a method of wrapping gold or K gold foil on the surface of silver or other types of metal carcasses by mechanical rolling or high-temperature welding. Tips: The thickness of the gold overlay here is defined by pure gold. All color gemstones are naturally occurring and it’s to be assumed many are heat treated.Gold-filled: The domestic standard QB/T 1131-2005 "Regulations on the Thickness of Jewelry Gold Covering Layer" defines the "Gold-filled cover layer" as follows: "The gold cover obtained by firmly wrapping gold foil on the substrate of the jewelry product by mechanical processing The layer is called the gold-clad covering layer, and it is required that the thickness of the gold covering layer is not less than 0.5μm (micrometer).
