Gold can be classified as one of the most precious metals. One of the properties of gold is its high malleability and softness, which makes it impossible to use it alone and must be combined with other metals to obtain the necessary strength. Therefore, all gold that is combined with other metals is called alloy, except for 24 carat gold, which is pure. Among the metals that are added to gold to increase its strength, we can mention silver, palladium, nickel and copper.
Carat gold
Carat is actually a unit that measures the purity of gold and other metals. The higher the presence of other metals in gold, the lower its grade and subsequently its price is also lower and vice versa. People's interest in carat is different in different countries, for example, in our country people like 18 carat, while in Arab countries this number is 24.
Gold color The color of gold can vary depending on the alloy used in it. In the alloy of gold, copper and silver, if the amount of gold is more, the gold turns yellow. In the alloy of gold, silver, copper and zinc, if the amount of silver is more, green gold is obtained. In the alloy of gold and copper, if the amount of copper is more, we will have pink gold, and in the alloy of gold, nickel, palladium, silver and zinc, if the ratio of all is constant, we will have white gold.
