Things that are made of copper include alloys, pipes, wires, coins, electronics and poisons. It is also a key element in creating bronze and brass.Continue Reading
Copper has been used for thousands of years, and it exists as a pure element in a variety of forms. Pure copper has a reddish color, while oxidized copper has a turquoise color. The properties of copper are conductivity, malleability and resistance, and this metal provides the lowest electrical resistance next to silver. It is also very ductile and easily drawn into thin wires.
Copper ores are much more abundant than native copper and are the major source of copper worldwide.
Copper is used in numerous alloys, such as brass and bronze. When combined with other metals, this transition metal increases their strength and usefulness. Pure copper is also useful in making pipes and wiring used in most households. Another common use of copper is in making coins; although pennies in the United States are not made of pure copper, many other countries still use pure copper to create coins. As copper is a great conductor, it is commonly used in manufacturing electronic products. Additionally, some pesticides are copper based, such as copper sulfate and copper hydroxide.Learn more about Chemistry
The two most dangerous and fast-acting poisons are hydrogen cyanide and botulinum toxin, which can kill within very quickly, according to Planet Deadly and the Organisation for the Prohibition of Chemical Weapons. The speed with which poisons kill depends on the dosage and route of entry.Full Answer >
Examples of alloys are brass, bronze, pewter and steel. Precious metals such as gold and silver are also alloyed with other metals to make durable jewelry.Full Answer >
Zinc chromate primarily is used as a corrosive-resistant coating for metals with zinc plating or alloys containing zinc. Zinc chromate is also used in spray paint and linoleum production. Although it is a known toxin and carcinogen in humans, zinc chromate primers are used in the automobile, aviation and aerospace industries to prevent corrosion and organic growth on metal components.Full Answer >
Steels are alloys that have iron content ranging from more than 99 percent to less than 60 percent, with carbon and other metallic elements to harden the alloys or give them other properties. Iron by itself is relatively soft and prone to rusting. Steel is hard and corrosion-resistant.Full Answer >
