Copper is also used in parts for refrigerators, electronic ovens, TVs, VTRs, air conditioners, and acoustic devices. If we understand that every button is made with copper, we may understand how much copper contributes to modern civilizations.

The materials called CDA194 and CDA195, manufactured by the U.S. once prevailed in the global semiconductor market. With the new materials developed by sampo entering the market, Korea was able to show off its technology to the world. The Company went as far as to export manufacturing technology to the German market. This marked the first exported sophisticated technology. Copper is indispensable to the modern industries. This holds true for telecommunications equipment. Copper enabled the advancement of all telecommunications equipment including telegrams, telex, facsimile, wireless units as well as cables and antennae thanks to its excellent conductivity.

Copper is a material often used in aircrafts to maintain its complicated functions. Different cables, hydraulic pipes, and switch contact points in aircrafts have to use copper. The materials should be light in weight, durable, highly resistant to corrosion, and flexible enough to endure vibrations; Copper is the material that fulfills all such requirements.

Copper is an ideal piping material in view of corrosion resistance, hygiene, and economical aspects not only for heating coils in the "ondol" floor heating system, but also for waterworks, water supply, hot water supply, cooling and heating, gas, fire extinguishing, and sewage drainage piping.

Copper roofing material is more widely used in the U.S., Europe and Japan due to its semi-permanent life expectancy and its excellent decorative design with the mystical color change of verdigris, not requiring additional painting or coating. It also remains stable in the ever-changing weather conditions, especially in the urban industrial area where the atmosphere is filled with strong acids such as sulfurous acids.

The usage of copper as roofing material for buildings to be preserved permanently such as the National Assembly, the National Museum of Korea, or temples and general houses is on the rise. sampo reproduced the traditional Korean roofing style in the Independence Hall and temples across the country in accordance with the standards specified by the Office of Cultural Properties, thereby opening a new chapter in the Korean roofing culture.

With the exception of becoming worn out or the currency unit changes, coins, on the other hand, may be used continuously and cannot be collected to be reused.

Coins change color depending on the alloy ingredient of copper. The coins used in Korea, denominations of 500 won and 100 won are made of cupro-nickel (alloy of copper, zinc, and nickel), 70% of the globally distributed coins use this material, whereas 10 won coins use brass (alloy of copper and zinc).

The reasons for using copper alloy materials in coins since old times are threefold. First, copper alloy materials do not corrode easily and have a long distribution life. Second, the materials can be collected and reused at all times. Third, coins pass through many hands and require hygiene. Copper allows the surface of the coins to be free of germs thanks to copper's unique anti-microbial ability, free from concerns over infections.

Take the brewing industry for example. There are several types of alcoholic beverages such as makgeolri (unrefined rice wine), wine, beer, and whisky.

Whiskey or beer is the same. It is worthwhile to note that the scotch whiskey brewers in Scotland use copper plates in various kilns.

The saying that "the liquor tastes best when brewed in copper containers or copper pipes" still holds true. In the pharmaceutical industry, vitamin tablets are made using copper. Usually, those who are feeble or tired take vitamins to relieve the fatigue and many of these vitamins have red and yellow coating. These colorings are usually sugar coating and ingredients of vitamins are included in this colored layer. Copper kilns are used in making these sugared tablets because copper has superior thermal conductivity and corrosion resistance.

Confectionary makers also use copper a great deal. Large confectionaries use copper kilns to boil red beans or to make toffees. Copper allows uniform processing of target products.

The materials should have good molding and processing capabilities as well as good appearances. When making musical instruments, only few metals can meet the

In addition to the use of copper in the above areas, the scope of application of cooper is ever so broad in various furniture decorations, locks, medical devices, and ornaments. The importance of copper can be summarized thus: "Without copper, modern civilization would not have made advancement."

A wide range of cartridge cases from sporting ammunitions used for hunting and sports and cartridge cases used in small arms to ammunition for field guns are made with copper alloys. Copper alloy s are reusable at all times after collecting and recycling.
