Gold alloys

Gold alloys
Gold is a metal known for its beauty and durability. But pure gold, although beautiful, is not always perfect for various purposes. Often to give it the necessary properties, such as strength, color or price, it is mixed with other metals. The resulting mixtures are called alloys.
A variety of gold alloys
Gold easily races with many other metals, forming an incredible variety of alloys. The most common additives are silver, copper and palladium. Each added substance affects the final result: color, strength, wear resistance. For example, the addition of silver makes golder gold, and copper - reddish. Almost all gold jewelry are alloy, not clean metal. This is due to the fact that pure gold is too soft and is easily deformed. Alloy is much stronger and more durable.
Gold sample: how much gold is in the alloy?
To determine how much gold is contained in the alloy, the concept of a test is used. The test is a designation of the fraction of gold in the alloy, usually expressed in carats or ppm. For example, gold 585 samples contains 58.5% gold. Gold products of 750, 900 and 958 have a higher sample. The higher the sample, the more gold in the alloy, and the, respectively, the product is more expensive. Of course, it is important to understand that the addition of other metals not only gives the necessary properties, but also significantly affects the cost of the product.
Practical use of gold alloy
Gold alloys are used not only in jewelry. In dentistry, gold is used for the manufacture of seals and crowns due to its resistance to saliva and food acids. In electronics, due to the high electronics of gold alloys, it is used in contacts and various electronic components. Despite the variety of applications, it is in jewelry of gold alloys, with their variety of shades and shades, they find the widest application, delighting us with their beauty and charm for centuries.
