Copper casting sculpture plays an important part of sculpture art culture. After long history of development, the technology is getting mature. Here we talk about Brass Sculpture and Bronze sculpture, which both contain the copper materials.

Brass alloy materials generally are composed of copper and zinc. The brass composed of copper and zinc is called ordinary brass. If it is composed of more than two elements, it is called special brass. Brass has strong wear resistance, usually used in the manufacture of valves, water pipes, machine connection pipe and radiator. Brass refers to smelting copper, the world's first smelting copper was found in China's Shaanxi. In 1973, a semi-circular brass piece and a brass tube were found in the ruins of the Jiangzhai cultural site in Lintong, Shaanxi province,which was dating back to the year 4700 or so.

Bronze is the earliest alloy in the history of metal smelting. Compared with pure copper, bronze has high strength and low melting point (the melting point of bronze will be reduced to 800℃ with 25 percent of tin. The melting point of pure copper is 1083℃). Bronze has good casting ability, wear resistance and stable chemical properties. Bronze casting art is an important branch of sculpture art, the contemporary copper casting sculpture is inheriting the traditional copper casting and Bronze sculpture is one of copper sculptures. A hard sculpture made of bronze (copper, tin and lead).

On the basis of art, both brass and bronze materials have absorbed more abundant artistic elements. Through continuous technological innovation, it has undergone fundamental changes in its artistic concepts, expressive themes and artistic forms and become an important cultural carrier and cultural symbol expressing the spiritual and cultural life of the people and carrying the spirit of The Times.
