（1） 红铜又称纯铜、紫铜，采用的是锻造工艺。
(1) Red copper, also known as pure copper and copper, is forged.
（2） 红铜的质地软，延展性好，可塑性强；导电性好（金属含量高）。其中延展性是铜雕装饰的重要特性。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。锻铜浮雕工艺，是我国传统手工艺百花中的一枝奇葩。
(2) Red copper has soft texture, good ductility and plasticity, and good electrical conductivity (high metal content). Among them, ductility is an important characteristic of bronze carving decoration. 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. Forged copper relief technology is a wonderful flower in the traditional handicraft of our country.
（3） 红铜浮雕耐腐蚀、不褪色、制作工期长，适合室外应用的优点，是铜浮雕最常使用的材料。其中红铜浮雕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。
(3) Copper relief is the most commonly used material for copper relief, which has the advantages of corrosion resistance, non-fading, long production period and is suitable for outdoor applications. Among them, the metallic luster of red copper relief makes it have stable and noble quality while expressing modern feeling.
（4） 红铜浮雕平均价格为每平方米2800元左右
(4) The average price of red copper relief is about 2800 yuan per square metre.
