Copper has excellent electrical and thermal conductivity, ranking among the top of all engineering metal materials, which is the main basis for its pivotal role in the current electrification and electronic information society. Copper also has many excellent comprehensive performance: it is the atmosphere, seawater, soil and many chemical media have a strong corrosion resistance; it is used in the structure of the rigid and flexible, flexible, friction, anti-wear; it has a colorful appearance, is a symbol of people's favorite, rustic elegance. In addition to the above performance, it has a series of good processing, casting, welding, easy cutting and other process performance, so that it has gained economic and wide range of applications.
--Housing construction accounts for 48%: including: piping systems (water, heat, gas, fire sprinkler, etc.); housing facilities (air conditioning, refrigerators, etc.); building renovation (roofing, gutters, decorative, etc.); communication lines (sound, image, data, etc.); power systems.
--Equipment production accounts for 41%: including: industrial equipment (motors, transformers, etc.); transportation (automobiles, railroads, airplanes, etc.); electronic devices; light industrial goods (household appliances, meters, tools, etc.)
--Infrastructure 11%: including: large-scale projects (transportation facilities, petrochemical industry, mining and metallurgical industry, etc.); electric power utilities (transmission, distribution, etc.); and communication networks.
It is worth noting that the construction of housing and people's production level is directly related to the application of copper in this area occupies the largest proportion; especially China's residential construction as an important link in pulling the development of the national economy as a whole, which can be seen, and actively promote the application of copper on the national economy and people's livelihood of the important role.
