Bronze is an alloy composed of copper and tin, though sometimes other substances, such as arsenic, are substituted for the tin. Bronze is harder than pure copper, making it a more durable material for weapons, hardware and sculpture.


Bronze has a cost that varies according to its fluctuating value in the market. Different scrap yards, antique dealers and other buyers all pay different rates for the alloy.


Silver is the most conductive element. However, it is not often used to conduct electricity because it is more expensive than copper and tarnishes more readily than gold, particularly in environments that contain sulfur or ozone.


Water can easily conduct electricity if it contains ionic compounds, but pure water does not conduct electricity. Pure water is rarely found in nature, therefore the majority of water found on Earth does conduct electricity.


To clean a bronze item, rinse it, apply baking soda and lemon juice, buff the bronze, wait 30 minutes, rinse the item, and dry it with a towel. This 40-minute process requires gloves, a bowl, a spoon, baking soda, a lemon, a knife, a towel, a sink and a polishing cloth.


Bronze is an alloy made of 88 percent copper and 12 percent tin. Other metals, such as aluminum, zinc, lead and silicon, are added to it frequently. It is malleable, ductile, lustrous, hard, golden brown in color, and a good conductor of heat and electricity.


Carbon is the only nonmetal outside of the metalloid group that conducts electricity. Metalloids are a group of related nonmetal elements with some metal traits, including the ability to conduct electricity. Other nonmetals are electrical insulators.


There is no metal that does not conduct electricity entirely, but there are some metals that are less effective conductors than others. Metal atoms have electrons in their outer shells that are not tied to any particular atom and can flow freely within the metal when electricity is applied.


Metals conduct electricity well due to the fact that the outermost electrons in their atoms are held by weak atomic forces, allowing these electrons to flow easily from one atom to another. This flow of electrons is what lies at the heart of an electric current.


The metals that conduct electricity the best are silver, copper and aluminum. Both copper and aluminum are used extensively in electrical wiring. Silver, though it conducts electricity better than either of the other two, is too expensive for common usage.
