Copper is naturally antibacterial. Brass doorknobs, handrails and fingerplates are excellent choices for public buildings and will prevent the spread of bacteria.
Copper tools will not cause sparks, making them the tools of choice when working around explosives.
Copper is 100% recyclable and nearly 80% of the copper that has been produced is still in use today. Copper can continue to be recycled without any changes to its properties. In fact, it retains 95% of its original value.
Copper is often referred to as “man’s eternal metal”. It’s highly durable, long lasting and can be used in all applications of life.
The average person will use 1500 pounds of copper just to enjoy today’s standard of living. (Think computers, telephones, automobiles, etc.)
U.S. coins today consist of a solid copper core and layer of copper-nickel alloy.
A copper earthing system could save the lives of people who are struck by lightning, as well as save the homes and structures that are damaged from lightning strikes.
Copper is our oldest metal. There are records dating its uses that date back 10,000 years. Egyptians had a symbol that signified copper.
The statue of Liberty contains a whopping 179,000 pounds of copper.
Copper is quite resilient and can withstand harsh storms and deplorable weather.
Professional chefs prefer copper cookware to stainless steel, as it thoroughly and evenly heats the contents of the bowl, avoiding heat spots.
There are coins that have more copper in them than pennies themselves. This may be hard to believe thinking about the color of pennies. They look like copper so they must be, right? Well, up until 1982, pennies were actual 95% copper. However, pennies currently consist of a zinc alloy, which only has a coating of copper; other coins, like dimes, are 75% copper.
Copper is completely recyclable, and luckily most if it has been recycled already. About 80% of the copper that we see today is recycled from original copper, retaining almost all of its original characteristics.
Copper is not only in coins and structures, it is also in our bodies as well. The human body needs copper to keep things such as our immune system, nervous system and heart working efficiently. Lower volumes of copper can actually lead to bone density and low white blood cells. Great sources of copper are found in shellfish, whole grain cereals, soy milk, mushrooms, and seeds. Word of advice: swallowing coins with copper will not make you healthier.
Contractors and chefs prefer copper materials, as they do not cause sparks, and are safe to use around flammable materials.
Electrical wiring, pipes, and most household appliances consist of copper, making an average home employ over 400 lbs. of copper. Cars use a lot of copper as well, usually between fifty and 100 lbs.
Subsequently, It takes over 1,000 lbs. of copper to maintain the standard of living for one person.
Copper has been used for as long as we can remember. The Egyptians had the ankh symbol to represent copper, and pyramids in Egypt used copper for water plumbing.
Copper can be alloyed with tin to make bronze and alloyed with zinc to make brass.
Although the Dead Sea Scrolls have been known to be made with rare animal skins, one that was recovered contains copper.
Copper is everywhere: TVs, radios, electrical wiring, plumbing, washers and dryers. It is often alloyed with zinc or tin to make brass or bronze, giving it a golden-like color.
Chile was the top mine producer of copper with at least one-third world share followed by the United States, Indonesia and Peru.
It was in use at least 10,000 years but 95% of all copper ever mined and smelted has been extracted since 1900.
Copper FAQs
Copper is a fascinating element with a rich history and countless uses in our modern world. Here are some of the most commonly asked questions about copper, answered in detail:
1. What is copper?
Copper (Cu) is a chemical element with atomic number 29. It’s a reddish-brown metal known for its excellent electrical and thermal conductivity, surpassed only by silver. Copper is naturally soft, malleable (can be shaped into sheets), and ductile (can be drawn into wires). Interestingly, copper can also occur naturally in its metallic form, unlike most metals.
2. What are the properties of copper?
- High conductivity: Copper excels at conducting electricity and heat. This makes it ideal for electrical wiring, heat sinks in electronics, and heat exchangers.
- Malleability and ductility: Copper’s ability to be shaped and drawn into thin wires makes it crucial for various applications, from electrical cables to plumbing pipes.
- Corrosion resistance: Copper resists corrosion from fresh water, making it a reliable material for pipes and fittings. It also shows good resistance to many other elements.
- Antimicrobial properties: Copper has inherent antimicrobial properties, meaning it can kill bacteria and fungi on its surface. This is beneficial for applications like doorknobs and antimicrobial surfaces in hospitals.
3. How is copper used?
Copper has a vast range of applications across different industries:
- Electrical wiring: Copper is the standard for electrical wiring in buildings due to its excellent conductivity.
- Plumbing: Copper pipes are widely used for both hot and cold water due to their durability, corrosion resistance, and ability to resist freezing.
- Electronics: Copper is essential for various electronic components like circuit boards, wires, and heat sinks.
- Construction: Copper is used in roofing, cladding (exterior building covering), and other architectural applications.
- Consumer goods: Copper finds its way into cookware, doorknobs, and other everyday items.
- Industrial applications: Copper is used in motors, generators, transformers, and other industrial equipment.
4. Does copper turn green?
Yes, copper can develop a green patina over time when exposed to air and moisture. This patina is actually a protective layer composed of copper carbonate and other compounds. While it may not be aesthetically pleasing in some cases, it doesn’t harm the copper itself and can even enhance its durability.
5. Is copper safe?
Copper is generally safe for most people in the amounts typically encountered. However, high doses of copper can be toxic. Copper pipes are considered safe for drinking water, but if there’s high copper content in the water source, it can leach into the water. It’s always best to follow recommended guidelines for copper levels in drinking water.
6. What are some interesting facts about copper?
- Ancient metal: Copper is one of the first metals humans used, with evidence of its use dating back to 10,000 BC.
- Natural occurrence: Unlike most metals, copper can be found in nature in its pure metallic form.
- Essential nutrient: Copper is a vital trace element needed by the human body for various functions.
- Space exploration: Copper plays a role in spacecraft construction due to its conductivity and heat resistance.
