First, plumbing systems
As copper water pipe has many advantages such as beautiful and durable, easy installation, safety and fire prevention, health care, etc., it makes it significantly superior price-performance ratio compared with galvanized steel pipe and plastic pipe. In residential and public buildings, used for water supply, heating, gas supply and fire sprinkler systems, increasingly favored by people, becoming the current material of choice.
In developed countries, copper water supply system has accounted for a large proportion. New York, the United States, known as the world's sixth tallest building in the Manhattan Tower, which is only a water supply system, the copper pipe used to 60,000 feet (10,000 kilometers). In Europe, drinking water with a large consumption of steel pipe. Britain's drinking water with an average of 1.6 kilograms of steel pipe consumption per person per year, Japan for 0.2 kilograms.
Because galvanized steel pipe is easy to rust, many countries have been expressly banned. Our country in the construction of housing to promote the use of copper piping system, imperative.
Second, house decoration
In Europe, the use of through-board production of roofs and eaves has been a tradition. Scandinavian countries even use it for wall decoration.
Copper atmospheric corrosion resistance is very good, durable, can be recycled, it has a good processing can be easily made into complex shapes, and it also has a beautiful color; therefore, it is very suitable for use as a house decoration. It has a long history of application on the roofs of ancient buildings such as churches, and still emits an attractive luster; and it is increasingly used in the construction of modern large buildings and even apartments and houses.
For example: in London, on behalf of the modern British architectural art of the "Commonwealth Commission" building, the complex shape of the roof, built with copper, weighing about 25 tons; in 1966 the opening of the Crystal Palace Sports Center, made of copper 60 tons of wavy roof and so on. According to statistics, the average annual consumption of copper sheets used for roofing is 0.8 kilograms per person in Germany and 0.2 kilograms in the United States.
In addition, the house decoration, such as: door knobs, locks, louvers, press bar, lamps, wall decorations and kitchen utensils, etc., the use of steel products are not only durable, sanitized and hygienic, but also decorated with an elegant atmosphere, loved by people.
Third, statues and crafts
There is no metal in the world, like copper, can be widely used in the manufacture of various crafts, from ancient times to the present, enduring. Today's urban construction, a variety of monuments, cast bells, tripods, statues, statues, antique products, etc., a large number of cast copper alloy.
Modern musical instruments, such as flute made of white copper, saxophone with brass material. A variety of exquisite works of art, inexpensive and beautiful gold-plated and imitation gold, imitation silver jewelry also need to use a variety of components of copper alloy.
In 1996, the Hong Kong Temple of Heaven Buddha, the use of tin, zinc, lead bronze casting splicing and become, 26 meters high, weighing 206 tons. 1997, the completion of the South China Sea Goddess of Mercy Buddha in Putuoshan, Zhejiang Province, 20 meters high, weighing 70 tons, is the world's first use of gold-imitation materials to build a giant bronze statue. Later in Wuxi, the 88-meter-high bronze Shakyamuni Buddha statue was completed.
Fourth, coins
Since human ancestors used coins for trading, copper and copper alloys have been used to make coins, which have been passed down from generation to generation and inherited to this day. With the development of modern automatic coin-operated telephones, car rides, shopping and other people-friendly activities, the amount of steel used for coinage continues to increase.
In the application of copper coins, in addition to changing the size, it is easy to use different alloy compositions and change the color of the alloy to manufacture and distinguish different denominations of currency. Commonly used are "silver coins" containing 2.5% nickel, brass coins containing 20% zinc and 1% tin, and "copper" coins containing small amounts of tin (3%) and zinc (1.5%). Thousands of tons of copper are consumed worldwide each year to produce copper coins. The Royal London Mint alone produces 700 million copper coins per year, requiring about 7,000 tons of metal.
