随着现代艺术运动的不断发展，雕塑也进入了一个更加无拘无束的时代。机器大工业的发展为雕塑的材料应用开拓了新的领域，大量的金属加工手段被运用。当代雕塑中有五分之四以上的作品是以金属为材料的。
With the continuous development of modern art movement, sculpture has entered a more unrestrained era. The development of machine industry has opened up a new field for the application of sculpture materials, and a large number of metal processing methods have been used. More than four fifths of contemporary sculptures are made of metal.
造成这种现象的原因并不是偶然的，人类的文明进程很大程度上归功于金属材料加工手段的进步，这使得金属具有极大的优越性——能够切割、焊接、铸造、锻打，也可以打磨、抛光以及上锈，能够将铜、铁、钢等各种材料的性能和材质的美感得到充分的发挥。
The reason for this phenomenon is not accidental. The progress of human civilization is largely due to the progress of metal material processing means, which makes the metal have great advantages - it can cut, weld, cast, forge, polish, polish and rust, it can give full play to the performance of copper, iron, steel and other materials and the aesthetic feeling of materials.
