Brass is good
Special tips
1. Copper pots and pans safety identification methods: copper cookware specifically used for cooking generally have a layer of stainless steel inside the pot, there are also a few tin inner layer. Copper is particularly thermally conductive and reacts strongly to anything that comes into contact with it - including air, moisture, food ....... A stainless steel interior prevents copper from touching or reacting with food, but pans with a tin interior tend to wear out, exposing the copper underneath, so use caution.
2. Copper pots are not suitable for boiling medicines. Copper is chemically unstable and oxidizes easily, reacting with the chemicals in Chinese medicine and affecting its efficacy.
Safe use of copper pots
1. Stay away from rust. Copper rust can be born after "copper green" that is (alkaline copper acetate), as well as blue alum (copper sulfate). These two toxic substances, can make people nausea, vomiting and even poisoning. So there is a patina of copper tableware, do not use.
2. Be wary of breakage. Never use copper pots without inner layer, or suspect that the inner layer has been damaged copper to cook or serve food.
3. Be careful with copper from tourist destinations. Copperware purchased in places like India or from the Middle East should be used for decoration, not as cooking utensils.
The most common use of copper is in the manufacture of electrical wiring, which is usually made of pure copper, because it is second only to silver in electrical and thermal conductivity, but much cheaper than silver.
And copper can be used to make a variety of alloys, the important alloys of copper are the following:
Brass brass is an alloy of copper and zinc, because of the color yellow and so named. Brass has good mechanical properties and wear resistance, and can be used to make precision instruments, parts of ships, and shells for guns. Brass knock up sound good, so gongs, cymbals, bells, horns and other musical instruments are made of brass.
Navigational brass copper and zinc, tin alloy, resistant to seawater erosion, can be used to make ship parts, balancer.
Bronze copper and tin alloy called bronze, because the color green and named. It was a common alloy in ancient times (e.g., Bronze Age China). Bronze generally has good corrosion resistance, wear resistance, casting and excellent mechanical properties. Used in the manufacture of precision bearings, high-pressure bearings, seawater corrosion-resistant mechanical parts on ships, as well as a variety of plates, tubes, rods and so on. Bronze also has a perverse property - "heat shrinkage and cold expansion", used for casting statues, expansion after cooling, can make the brow clearer.
Phosphor bronze copper alloy with tin and phosphorus, hard, can make springs.
White CopperWhite Copper is an alloy of copper and nickel, its color and silver, silver, not easy to rust. Commonly used in the manufacture of coins, electrical appliances, instruments and decorations.
Eighteen open gold (18K gold or called rose gold) 6/24 copper and 18/24 gold alloy. Reddish yellow, hard, can be used to make jewelry and decorative items.
Medicine and Health80% of infectious diseases are spread through contact. Despite strict infection prevention measures taken by health professionals, including frequent hand washing and frequent disinfection of surfaces, the number of infections among patients during hospitalization is increasing every year indicating that these measures are not enough. There are hundreds, if not tens of thousands, of colonies of infectious bacteria on frequently touched surfaces in the intensive care unit. Patients, family members, doctors, nurses and cleaning staff come into contact with these surfaces on a daily basis. Because bacteriostatic copper naturally inhibits and consistently kills bacteria, it plays a supportive role in combating infections. An additional line of defense can now be placed on these contact surfaces.
Schools and Public ****BuildingsThe Centers for Disease Control and Prevention (CDC) lists five factors conducive to the spread of methicillin-resistant Staphylococcus aureus (MRSA), as well as other contagious bacteria: crowding, touching, contaminated contact surfaces, injured skin (e.g., cuts, scrapes), and lack of disinfection. These conditions are common in schools, dormitories, offices, and homes. The frequently touched surface environments in these buildings are ideal for the spread of bacteria, and some antibiotic-resistant bacteria can be cross-transmitted between healthcare facilities and social environments, increasing the likelihood of deadly outbreaks.
A 2009 study by the U.S. Centers for Disease Control and Prevention reported a seven-fold increase in community-acquired MRSA among outpatients from 1996 to 2006. Unlike hospital-acquired MRSA, community-acquired MRSA affects healthy children and adults. The aforementioned infections are growing at an alarming rate in schools and public **** buildings. Bacteriostatic copper surfaces can assist in the fight against MRSA and other bacteria in schools and public **** buildings. Stainless steel, biocides, and silver-containing coatings do not consistently kill these disease-causing bacteria.
Sports Between 20 and 30 percent of us don't realize we carry S. aureus, and sports equipment and devices are used regularly by large groups of people. The humid, hot conditions typical of these sports spaces are ideal breeding grounds for bacterial growth, and there's no doubt that the growth of staphylococcus attached to sports equipment is leading to an increasing number of infections.
Methicillin-resistant Staphylococcus aureus (MRSA) infections have been severely exacerbated in Nebraska senior high schools. The rate of MRSA infections in the surveyed schools increased from 4.4 percent in 2006-2007 to 14.4 percent in 2007-2008. MRSA infections per 10,000 wrestlers changed from 19.6 to 60.1, more than a threefold increase. Infections per 10,000 soccer players went from 5.0 to 25.1, a more than five-fold increase. These statistics illustrate the urgent need for sports equipment and frequently touched surfaces to be consistently effective against MRSA and other disease-causing bacteria* using materials that inhibit the bacteria.
Appliance Heating, Ventilation and Air Conditioning (HVAC) system components operate in warm, dark, humid environments, which are ideal breeding grounds for odor-causing substances and mold, which in turn impede system efficiency. Laboratory tests for odor-causing substances and mold have shown that copper materials can inhibit the growth of these microorganisms. After 24 hours of exposure to copper surfaces, total death of several common bacteria was observed. Aluminum, on the other hand, had no effect on any of the bacterial species. These test results demonstrate the superiority of copper surfaces over aluminum surfaces, which naturally inhibit the growth of odor-producing substances.

Natural Bacteriostatic Properties of Copper
Healthcare-Associated Infections (HAIs) place a heavy socioeconomic burden on people around the world. The U.S. Centers for Disease Control and Prevention (CDC) estimates that, combined with the significant costs paid by individuals, the U.S. spends between $35 and $45 billion annually on healthcare-associated infections. These infections are caused by bacteria that are active on objects we touch every day. Those antibiotic-resistant bacteria spread from healthcare settings to schools, homes, and public **** transportation venues. Despite constant hand washing and cleaning, these bacteria continue to multiply at an alarming rate.
Copper, is currently the only solid material registered by the U.S. Environmental Protection Agency (EPA) for its bacteriostatic properties. Copper inhibits the growth of disease-causing bacteria 24/7, killing more than 99.9% of (specific) bacteria on its surface within two hours. At the same time, it minimizes "secondary contamination" of the contact surface, which is far more effective than other materials, including silver-containing coatings, stainless steel, antimicrobial plastics, and other materials, so that you can keep away from the attack of disease-causing bacteria. Laboratory tests on the efficacy of six types of bacteria have shown that, under regular cleaning, Copper Inhibitor TM can kill more than 99.9% of the (specific) bacteria on its surface within two hours: methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, Staphylococcus aureus, Enterobacter aerogenes, Pseudomonas aeruginosa, and Escherichia coli type 0157H7.
Scientific evidence supporting the U.S. Environmental Protection Agency's (EPA) registration and certification has demonstrated that Copper Inhibitor is the most effective* antibacterial material for contact surfaces and advocates globally for the use of this antibacterial material in medical devices, public ****transportation, educational institutions, and other areas in the fight against disease-causing bacteria.

[edit]Types of copper
Copper is used in the U.S., the United States and Canada as the main ingredient in the copper industry.
There are more than 350 EPA-registered bacteriostatic copper and copper alloy products and materials in a wide variety of colors and surface textures, as well as a wide range of textured and ductile options to meet the needs of different users of bacteriostatic public ****contact surfaces. In addition, do not wax, stain, paint, varnish, or add coatings of any kind to bacteriostatic copper surfaces. Even though the copper alloy will rust to varying degrees, its bacteriostatic properties will not be impaired.
[edit]Role of copper in the human body
Foods high in copper
Main entry: copper nutrition
Copper ions (copper) are essential elements for living things, whether animals or plants. A deficiency of copper in the body can cause anemia, hair abnormalities, bone and artery abnormalities, and even brain disorders. In excess, however, it can cause cirrhosis of the liver, diarrhea, vomiting, movement disorders and perceptual nerve disorders.
In general, beef, sunflower seeds, cocoa, black pepper, lamb's liver and so on are rich in copper.
