Gold alloys<\/a> are represented by different variants, they differ in the content of precious metals<\/a>. And there are low-grade and high-grade compositions. The intermediate variant is the metal marked 525 Sample<\/a>. It is versatile, used in industry, medicine, jewelry. Products that are made on its basis are wear-resistant. In addition, the metal has another feature - it changes color<\/a> depending on the ratio of additives. To use it correctly, you need to learn more about these and other properties.<\/p>\n\n\n\n

525 hallmark - what kind of metal is it<\/h2>\n\n\n\n

The alloy is assayed by metric system<\/a>. The numerical designation is the amount of gold contained in 1,000 weight parts of the material being tested. If you need to determine the fraction of precious metal in 1,000 g of an alloy, it is easy to do. <\/p>\n\n\n\n

The amount of gold in this case will be 525 g. <\/p>\n<\/blockquote>\n\n\n\n

The rest of it is. ligatures<\/a>The use of Au in various industries would be difficult because of its brittleness, softness, and low ductility. Without them it would be difficult to use Au in various industries because of its brittleness, increased softness and low ductility. The percentage of precious and other additives is 52.5% and 47.5%.<\/p>\n\n\n\n

Why is 525 proof silver confused with 925 proof silver?<\/h2>\n\n\n\n

Often metal with hallmark 925<\/a> is considered to be a white gold alloy. In the same way, the variety of material with a 525 assay is misunderstood. In fact, the carat and metric system does not have such a variant of the hallmark. But that doesn't mean the alloy doesn't exist. It is used in various spheres, but much more rarely in jewelry. Just as a result of the infrequent use of this metal, many people have no idea that it exists, mistaking it for silver alloy<\/a>. In addition, there are other reasons:<\/p>\n\n\n\n
