白银是一种贵金属,长期以来因其优良的金属性质而被广泛地用于人们生活、生产的各个方面。银的硬度在金与铜之间,熔点为961.93℃,比重10.5①,银有最佳的传导性,又有优良的延性(细而不断)和展性(薄而不裂),且有美丽的色泽,很早就被用来制作器物和首饰等,所以银这种金属有着较高的使用价值,又有便于携带、切割、保存和按需重新熔炼、重新制作的特点,因此历史上白银曾被世界许多国家和地区选为制作货币的材料,它也曾是我国一种重要的货币。
Silver is a precious metal that has long been widely used in all aspects of human life and production because of its excellent metallic properties. Silver hardness between gold and copper, the melting point of 961.93 ℃, the proportion of 10.5 ①, silver has the best conductivity, but also excellent ductility (fine and continuous) and malleability (thin and not split), and beautiful Color has long been used to make utensils and jewelry, so the silver metal has a high value, but also easy to carry, cut, save and re-smelting, re-production features, so the history of silver It was chosen as the material for making money by many countries and regions in the world and it was once also an important currency in our country.
