紫铜又名红铜，就是铜单质，表面形成氧化膜后呈紫色，故一般称为紫铜。紫铜是比较纯净的一种铜，一般可近似认为是纯铜，导电性、塑性都较好，但强度、硬度较差一些。紫铜具有优良的导热性﹑延展性和耐蚀性。另外，紫铜还有良好的焊接性，可经冷、热塑性加工制成各种半成品和成品。由于紫铜具有上述的许多优点，所以人们在生产铜缸的时候，逐渐的加入紫铜缸，不仅色泽艳丽，容易加工，而且还大大的提高了观赏性能。
      Copper, also known as red copper, is a copper element. It is purple after forming oxide film on its surface, so it is generally called copper. Copper is a kind of relatively pure copper, which can be generally considered as pure copper. It has good conductivity and plasticity, but its strength and hardness are worse. Copper has excellent thermal conductivity, ductility and corrosion resistance. In addition, copper has good weldability and can be processed into semi-finished products and finished products by cold and thermoplastic processing. Because copper has many advantages mentioned above, people gradually add copper cylinders in the production of copper cylinders, which not only has bright color, easy processing, but also greatly improves the ornamental performance.
