alloy definition for kids
1 Copper is a good conductor of electricity and is often used for making wires. 2  At room temperature, mercury is the only metal that is in liquid form.  Aluminum is a good conductor of heat and is often used to make cooking pots. Pure aluminium is soft and weak, but it can form alloys with small amounts of copper, magnesium, manganese, silicon, and other elements to make alloys having a variety of useful properties. These alloys form vital components of aircraft and rockets. When aluminium is evaporated in a vacuum it forms a coating that reflects both visible light and radiant heat. These coatings form a thin layer of protective aluminium oxide that does not deteriorate as silver coatings do. There are a few more words you might hear when people talk about mixtures. We can't cover all of them, but we'll give you a quick overview of the biggies. Alloys are basically a mixture of two or more metals. Don't forget that there are many elements on the periodic table. Elements like calcium (Ca) and potassium (K) are considered metals. Of course, there are also metals like silver (Ag) and gold (Au). You can also have alloys that include small amounts of non-metallic elements like carbon (C). Metals are the key thing to remember for alloys. The main idea with alloys is that the combinations work better together than any of the metals do alone. (ăl′oi′, ə-loi′) n. 1. A metallic solid or liquid that is composed of a homogeneous mixture of two or more metals or of metals and nonmetal or metalloid elements, usually for the purpose of imparting or increasing specific characteristics or properties: Brass is an alloy of zinc and copper. 2. A mixture; an amalgam: Television news has ... 1 More iron facts. 2  Copper is a good conductor of electricity and is often used for making wires. 3  At room temperature, mercury is the only metal that is in liquid form.

Aluminium or aluminum (in the U.S. and Canada) is a chemical element in the periodic table with the symbol Al and atomic number 13. A silvery, ductile metal, aluminium is found primarily as the ore bauxite and is remarkable for its resistance to oxidation, its strength, and its light weight. Aluminium is used in many industries to make millions of different products and is very important to the world economy. The chemical symbol used for silver is Ag, this comes from the Latin word for silver, argentum. More silver facts. While aluminum is the most common metal found in the Earth's crust, the most common metal found on Earth is iron, mostly because it makes up such a large part of the Earth's core.
