Historical records show that copper has been used from ancient times to modern times for various purposes including medical, antibacterial and sterilizing purposes and its effectiveness has been proven. It is widely known that Hippocrates, often referred to as the “Father of Medicine” used copper to treat varicose veins and foot ulcers around 400 BC. In modern times, it is used as natural antibacterial and sterilizing agent in multi-use facilities to the extent that it is used as material for immigration desk at the airport and water tank to eradicate E-coli. Research has found that the natural antibacterial effect of copper works on bacteria and viruses such as E-coli and food poisoning bacteria, which is effective in preventing infectious diseases and cross-infection.
Bacteria recognizing copper ion as essential nutrients
Copper ions penetrating through cells
Cell membrane rupture
Membrane potential and cytoplasmic loss
Copper ions induce the formation of reactive oxygen species
Causing and accelerating additional cell damage
Disrupting bacterial cell respiration and metabolism
Dissolution by genome and plasmid DNA
Pure copper itself is very soft, but it can be used in various areas as its strength varies depending on processing method. In the past, during Joseon Dynasty, brass bowls (copper alloy) were very precious and they were abroad at high prices. In fact, copper has antibacterial properties and is rarely toxic to human body. The steamed rice in a copper bowl does not go bad even when it is kept at a room temperature for a long time and the reason why coins are put in sneakers is to use the sterilization and deodorization capability of copper. Copper is effective in preventing the reproduction of organisms on the surface and killing microorganisms, so large hospitals use copper as the material for elevator buttons or door handles where patients touch a lot and copper is also used as a sterilizer for ship floor.
The highest electrical conductivity next to silver (Ag) used in areas that require energization.
9 times better than steel, 24 times better than stainless steel and 40 times better than aluminum
Infection prevention effect with sterilization effect upon contact with bacteria and virus
Used for forging, copper foil and fine wire thanks to its excellent malleability and ductility.
Various colors can be made by surface oxidation treatment and alloying (art, architecture)
Excellent corrosion resistance by forming a protective film
