Facts About Copper Alloy
- Bronze and brass are the most well known copper based alloys.
- Brass is mainly zinc and copper.
- Bronze is mainly copper mixed with elements such as aluminium, tin, beryllium or silicon.
- Leaded yellow brass also known as copper alloy 360 is very easy to machine.
- Leaded yellow brass is the benchmark standard for machinability when working with metals.
- Brass is the standard alloy used when making instruments such as watches, navigational aids and clocks.
- Brass pins when rust free, where used in very early wool making tools.
- Brass is used for decorative gold coloured products.
- Bronze is far more resistant to corrosion and harder than pure iron.
- Bronze is also harder than pure copper, Egyptians used bronze for armour, weapons, sculptures and tools.
- Bronze expands when heated and is well suited for sculptures.
- Bronze contracts as it cools so sculptures are easy to remove from moulds.
- Bronze containing about 20-25 percent tin is called bell metal.
- Bronze with a tin content under 10 percent and a mixture of lead and zinc is called statuary bronze.
- Other copper alloys include copper-nickel-zincs and copper-nickels, there is many other alloys also.
Historical Facts About Copper
- Dating back more than 10,000 years, copper is the oldest metal used by humans.
- Neolithic man first used copper as a substitute for stone.
- Copper metallurgy emerged in Egypt around 4000 B.C. when copper was heated and cast into shaped moulds.
- In the Bronze age around 3500 B.C., copper was first alloyed with tin to create bronze, hence the name “Bronze Age”.
- The word copper, originated from the words aes Cyprium, meaning “metal of Cyprus” by the Romans.
- aes Cyprium was shortened to cyprium, then changed to coprum, and thereafter became known as copper in English.
- Many everyday items in ancient Egypt where made of copper including water vessels, razors, hand mirrors and chisels.
- Copper chisels where used to smooth the limestone blocks of the great pyramids.
- Copper was also important in agriculture, hoes and picks used to harvest crops was made of copper.
- Greek soldiers wielded bronze weapons and wore bronze armour.
- Egyptians performed medical operations with instruments made of copper-alloy.
- Food was cooked and served in brass or bronze kitchenware in ancient times.
- Bronze mirrors allowed people of high stature to admire themselves and their jewellery.
- Coins were made of copper and its alloys and were used by early traders and world travellers and still do today.
- Ornamental and ceremonial objects show the use of annealing and hammering, a process of heating and cooling to soften and temper metal.
- Cave dwellers from 10,000 years ago used copper tools to survive and copper axes as weapons.
- Mayans, Aztecs and Incans commonly used copper alloyed with silver and gold, when they reigned over South and Central America.
Natural Resource Facts About Copper
- Copper is a valuable and important metal, estimated resources of more than 8.1 trillion pounds, only 1.1 trillion pounds have been mined so far in history.
- Copper’s recycling rate is higher than any other engineering metal, the vast majority that has been mind is still in circulation.
- Post consumer scrap equates for nearly 50% of all recycled copper, such as discarded automobile radiators, electric cable and air conditioners
- The remainder of recycled copper is new scrap, such as turnings, chips and offcuts from screw machine production.
- Other sources of reclaimed copper include electrical plumbing tube, wiring, automobile radiators, cartridge cases and production scrap waste.
Communication Facts About Copper
- Structured wiring using twisted pairs of copper wire can achieve speeds up to 10 gigabits per second when transferring data between computers.
- Copper lines enable telephone companies to offer low-cost networking and communication options, using High-Speed Digital Subscriber Line (HDSL) and Asymmetrical Digital Subscriber Line (ADSL) technologies.
- Copper wires can be used to allow data and voice transmissions to run simultaneously on phone wires.
Electrical Facts About Copper
- The standard benchmark for electricity is copper, it conducts electrical current better than other metals except for silver.
- Copper is commonly refined to 99.98% purity before it is approved for many electrical applications.
- Connectors are required for the flow of electricity, copper is the favoured material for use in conductors and high current distribution for power or for data and telecommunication “signal’ level currents.
- Copper-wound stators and rotors are used to convert mechanical energy into electric current when used in electric power generators.
- Copper is used in the delivery of wind energy, based on its low electrical resistance, high-conductivity and resistance to corrosion.
- Die-cast copper rotors in electric motors has been the “holy grail” for motor manufacturers for many years.
- SUVs and hybrid cars use copper-wound induction motors that draw their power from batteries.
- Larger buses and hybrid trucks can be equipped with motors using highly efficient copper rotors, when road tested copper rotors reduced fuel costs by more than a third.
- Copper rotor motors are used in the world-renowned Tesla all-electric vehicles.
- Copper provides the matrix in the superconductors used in the CERN Large Hadron Collider in Switzerland.
- Copper is used as a heat exchange medium in hot water systems and solar heating.
Plumbing Facts About Copper
- Copper tubing was found in the plumbing system from the Pyramid of Cheops in Egypt, it was dated to more than 5,000 years old.
- Copper tubing is a major application for fuel gas, its becoming more common that home builders are using high-pressure lines and copper tubing is the most cost effective connecting ranges, gas ovens, water heaters, fire places, outdoor barbecues and clothes fryers to propane or a natural gas supply.
- Metal manufacturers introduced a new type of lightweight yet durable drawn copper tube around 1927, it could be quickly soldered together with other copper fittings.
- Copper tubing is the standard material used for indoor water systems in homes today.
Consumer Products Facts About Copper
- The oldest musical instruments were made with copper alloys.
- The largest swinging bell is called the “World Peace Bell”, its 12 foot high and 66,000 pounds in weight and made out of “bell bronze”.
- In the 17th century brass became the preferred material used for mechanical clocks because its easily worked and corrosion resistant, prior to the 17th century iron was the preferred material used.
- Copper and its alloys are widely used for coffins, plaques, vaults and cremation urns, because of its non corrosive and durable properties.
- Vessels to distil liquor and brew beer are made from copper, it helps keep the distillate sweet by removing unpleasant tasting sulfur based compounds from the alcohol.
