红铜又称纯铜、紫铜。红铜的延展性、导电性和耐腐蚀性很好，其中延展性是铜饰的重要特性。红铜的熔点很高，不易铸造，而良好的延展性弥补了这一缺点，因此能够很容易地加工成各种造型图案。暗红的金属光泽使其在表达现代感的同时还具有沉稳、高贵的品质，是铜饰中最常使用的材料。
Red copper is also called pure copper and purple copper. The ductility, electrical conductivity and corrosion resistance of red copper are very good, and ductility is an important characteristic of copper ornaments. Red copper has a high melting point and is not easy to cast, and good ductility makes up for this shortcoming, so it can be easily processed into various shapes and patterns. Dark red metallic luster makes it have stable and noble quality while expressing modern feeling. It is the most commonly used material in copper decoration.
传统意义上紫铜浮雕也称纯铜浮雕，是用红铜薄板作为基材经过手工錾制而成，故又称锻铜浮雕。锻铜浮雕自二十世纪八十年代以来得到了空前发展，全国各地经济改革、招商引资的浪潮汹涌澎湃，文化搭台、经济唱戏成为各地政府争相仿效的成功手段。
Traditionally, copper relief is also called pure copper relief. It is made of red copper sheet as the base material by hand, so it is also called forged copper relief. Forged copper relief has developed unprecedentedly since the 1980s. The wave of economic reform and investment attraction is surging all over the country. Cultural platform and economic singing have become successful means for governments to emulate.
