No. This is a alloy of copper and zinc, and it is also the most suitable copper for jewelry. It is named after the color. High copper content is high, and it can withstand melting and polishing. Many musical instruments are made of brass, such as gong, trumpet, copper tube instrument and so on. The history of brass casting of Chinese people has been at least more than 3,000 years. For example, the Southern Baiyue nation in the pre -Qin era uses brass as a currency. In fact, copper itself is valuable, otherwise it will not be regarded as a symbol of power in the early days of Huaxia civilization. However, the value of the value of copper and copper jewelry is mainly due to historical changes. As a metal with a large amount of storage, the output of copper ore is very stable, and the good -looking copper can be used as jewelry.
