What is the difference between 18 carat and 24 carat gold?

Gold is used as an alloy with the size of metals. Copper, nickel, silver, palladium, etc. are good metals to combine with gold. Gold grade depends on the amount of gold in the alloy with which a certain product is made. The carat number of all gold is 24, and if the gold is 24 carat, it means that the gold is pure and not an alloy mixed with another metal. Usually, the higher the carat, the softer and more malleable gold is, that's why they combine gold with various alloys to make it more durable and reach the desired strength.

This gold is the purest type of gold that can be used in jewelry and crafts. 24 carat gold is completely yellow and shiny. Of course, keep in mind that 24-karat gold is softer and less strong as mentioned.

This type of gold is a famous alloy of gold and copper or gold and nickel, 75% of which is gold and the rest is other metals. This type of gold is very resistant and has all the characteristics of gold except softness and malleability.
