Rusty gold jewelry is a steel problem? You must not understand these

We all know that the raw material of gold jewelry is silver. When brown rust spots (spots) appear on the surface of the jewelry, people will think,'The raw material of gold jewelry is silver, why does it still rust? There must be a problem with the steel! 'In fact, this is a lack of a comprehensive understanding of silver, because silver will rust under certain conditions. Our jewelry processing factory often uses silver in the process of manufacturing gold jewelry, and I will share some silver tips with you. Silver has the ability to resist atmospheric oxidation---that is, rust resistance, and it also has the ability to resist corrosion in media containing acid, alkali, and salt---that is, corrosion resistance. However, the size of its anti-corrosion ability varies with the chemical composition of the steel itself, the state of mutual addition, the conditions of use and the type of environmental media. The silver models used in gold jewelry are different, and their corrosion resistance is also different. For example, 304 steel has excellent anti-corrosion ability in a dry and clean atmosphere. Once it is placed on the seashore with a lot of salt and sea fog, it will quickly rust, while 316 steel performs well. Therefore, rusting of gold jewelry is not necessarily a steel problem, but is determined by the silver material used by the manufacturer in the jewelry processing process. Not all types of silver material have the same performance, which can resist corrosion in any environment and achieve the effect of not rusting. It depends on which material has stronger corrosion resistance. Next: What is the difference between a necklace and a pendant?
