With the high performance of electrical and thermal conductivity, copper has played an important role in electrical industry and electronic industry. Additionally, copper has a series of good performance in machining, casting, wielding, and cutting, copper and copper alloys have a wild use in light industry, such as air conditioner, refrigerator, horologe, papermaking and printing machine, and pharmacy industry. Copper has strong corrosion resistance against water; a variety of copper alloy materials have became the standard shipbuilding material. Similarly, copper alloys have a wild range of application in automotive, railway, and aerospace industry. In architecture industry, copper water pipe is a typical application of copper alloys.
