18K gold has 75 % gold, and the remaining 25 % are other metals. In addition to white gold, 18K gold has other colors, and the hardness is higher than gold.nThe hardness of 18K gold is moderate, and it will not be like platinum or too soft. Therefore, the general difficult jewelry will be made of 18K gold.

Metal is a substance with metal characteristics synthesized by two or more metals and non -metals. Although gold is strong but not hard, when the metal needle is carved with real gold, it will leave obvious scratches. Bite with teeth can see tooth marks. Folk goldrs often bite with their teeth. The principle of hardness distinguishes authenticity. Gold is divided into pure gold and alloys, pure gold soft, and alloy hardness. Alloys are substances with metal characteristics composed of two or more metals and non -metals.nThe characteristics of gold mainly include: 1. Strong ductility. 1 ounce of gold can be pulled into 50 miles long, and its ductility makes it easy to cast and is a good choice for making jewelry. Gold is the strongest in the metal. 2. It has extremely high anti -chemical corrosion and color resistance resistance, and does not melt, oxidation, discoloration, and loss at 1,000 degrees Celsius at high temperature; 3. Have good conductivity and thermal conductivity; The effective cross section of the neutron is captured, and the reflection capacity of infrared rays is close to 100 %; 5. Due to softness, gold is easy to forge, and it is easy to extend. On the surface of pottery and glass.
