The current gold can be roughly divided into the following types: foot gold, thousands of gold, platinum, 3D hard gold, K gold, white K gold, gold plating, gold -plated gold. The foot gold and thousands of gold are collectively referred to as pure gold. At present, there are three types of gold in the Chinese market: four -nine gold, and the color is 99.99%. Three -nine gold, 99.9%, commonly known as thousands of gold. Two -nine gold, 99%, commonly known as foot gold.
physical properties 1. Color: The steam emitted when gold is melted is green; its gold powder is usually brown during the smelting process; if it is cast into a thin piece, it is even better Transmit green light. 2, ductility: abnormal strong. 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. 3, forgedness: secondary and none. It can cause extremely thin and easy to roll up. 1 ounce of gold can be hammered to 1 foot thick and 100 square feet with a large area of 4 million. The ancients hammered it into thin slices to decorate the temples and the palace. These can explain the strong flexibility and forgedness of gold.
