铜雕工艺品广泛存在于世界各地，而制作工艺却不尽相同，铜含量的标准也不相同，当然做出来的效果也是不同的。如果整个铜雕工艺品铜含量太高甚至达到百分之百也是不太现实的，相反铜含量太低也会出现各种问题，比如影响成品的色泽或者比较容易出现腐蚀的现象。

Copper carving arts and crafts widely exist all over the world, but the production process is not the same, the standard of copper content is not the same, of course, the effect is different. If the copper content of the whole copper carving handicraft is too high or even 100%, it is not realistic. On the contrary, if the copper content is too low, there will be various problems, such as affecting the color of the finished product or corrosion.
目前，中国、美国、泰国等国家所制造的铜雕工艺品的水平是不一样的，这主要就体现在铜含量和制作工艺上。美国制作的铜制品中，最低含铜量标准达到了90%，最高端的一些雕塑甚至达到了98%。而对于我们这些亚洲国家来说，铜雕工艺品中含铜量大概是55%左右。
At present, China, the United States, Thailand and other countries are not the same level of copper carving crafts, which is mainly reflected in the copper content and production technology. Among the copper products made in the United States, the minimum copper content has reached 90%, and some of the most high-end sculptures have even reached 98%. For Asian countries like us, the copper content in copper carving crafts is about 55%.
那些含铜纯度较高的铜工艺品中，抗氧化强，具有优良的导热性、延展性和耐腐蚀性，具有这些优越的性能使得整个工艺品不会因为长时间置于室外而出现腐蚀的现象，当然会生成一些铜绿，但是不至于锈得过于严重。
Among those copper handicrafts with high copper purity, they have strong oxidation resistance, excellent thermal conductivity, ductility and corrosion resistance. With these superior properties, the whole handicraft will not be corroded due to long-term outdoor exposure. Of course, some copper green will be generated, but it will not rust too seriously.
