铸铜雕塑主要有三种材料：
Cast copper sculpture has three main materials:
1。青铜：青铜具有良好的铸造加工性能，耐酸、碱、盐、耐腐蚀，适用于精密铸造，着色稳定，青铜铸造艺术也是我国雕塑艺术的一个重要分支，其主要成分是铜和锡，含量很小。铝和锌，国家标准为38；
1. Bronze: Bronze has good casting performance, acid, alkali, salt, corrosion resistance, suitable for precision casting, stable coloring, bronze casting art is also an important branch of sculpture art in China, its main components are copper and tin, the content is very small. Aluminum and zinc, the national standard is 38;
2。紫铜：也就是我们所说的纯铜。它的可塑性很好。它非常适合锻造工艺。如果不添加其他金属，则不适合铸造。
2. Copper: That's what we call pure copper. It has good plasticity. It is very suitable for forging process. If no other metal is added, it is not suitable for casting.
三。黄铜：黄铜具有良好的铸造工艺和耐腐蚀性，着色稳定，适合精密铸造；其主要成分为铜和锌，且含有极少量的铝和锡。
Three. Brass: Brass has good casting technology and corrosion resistance, stable coloring, suitable for precision casting; its main components are copper and zinc, and contains a very small amount of aluminum and tin.
