The color of gold is golden yellow, metal luster, and it is difficult to break down. The hardness is 2-3, the pure gold is 19.3, and the melting point is 1064.4 ° C; it has good ductility and can be pressed into thin foil. It has extremely high heat transfer and conductivity. The resistance of pure gold is 2.4P. Pure gold has good anti -chemical corrosion and is the best electroplating material.
Gold, as a precious metal, has good physical characteristics. "Real gold is not afraid of fire" means that the gold under the general flame is not easy to melt. The density is strong and the feel is heavy. Good toughness and ductility, good guidance. Pure gold has gorgeous yellow, but after incorporating other metals, the color changes greatly.

Different density According to calculations, under pure circumstances, the density of gold is 19.32 grams/cm3, and the density of the golden gold is 12.02 grams /cm3. Colors are generally white. 3. The melting point of the melting point is 1064 ° C, and the melting point of the golden gold is 1554 ° C. 4. Mo's hardness with different hardness is 2.5, and the hardness of Mohs of Gold Gold
