Metal is made up of a chemical element that is made up of single atoms that are lined up in a pattern in a crystal structure (atoms that repeat itself many times to line up in a pattern.) Some metals are called metal ore. Meaning it is a metal mixed with a different mineral or rock, the other part is an element. An element is the “materials” of matter. Metal is useful to man because it can be molded more easily than stone, and it is a good conductor of heat and electricity. There are many kinds of metal, copper, aluminum, iron, and steel. But the two kinds of metal I am going to use for this project is copper and aluminum. Copper is one of the most widely used metal except iron. One of the greatest abilities of copper is that it can form many alloys. Alloy is to combine two metals for it to be annealed. Anneal or annealing means to make it stronger. Aluminum was discovered by Charles Hall, aluminum is also one of the most widely used. Aluminum is known for its strength and lightweight. Metals have two types, non-ferrous metal and ferrous metal. Non- ferrous means that it does not contain iron, and of course, ferrous metals are compound metals that contain iron. A compound metal is two or more elements that is combined together. Two non-ferrous metals are copper and aluminum, and two ferrous metals are iron and steel. Strength is how much weight the material can hold, and toughness is the ability to absorb pressure until it cannot get anymore. Some

Iron and Uses Metal Metals Essay example

Design Breif and Introduction Wood, Metal and Plastics Timber There are three main types of timber: hardwoods, softwoods and manufactured boards. Here are a few examples: Name Softwood or Hardwood? Properties and colour Uses Metal Metals can either be ferrous or non-ferrous: ★ Ferrous metals contain iron and small amounts of other metals. Almost all ferrous metals are magnetic. But one major disadvantage of many ferrous metals is that they rust and therefore protective coats…

Chem: Iron and Metal Salt Solutions Essay

reactions between metals and their salts Introduction: Some metals are more reactive than others. In this experiment, a strip of metal is added to the solution of another metal’s salt. If the metal is more reactive than the metal whose ion is in the solution, this metal displaces the less reactive metal ion from the solution. This process is repeated with all the metals and all the metal salt solutions. Collecting this data will determine the order of reactivity of the metals. Aim: To determine…

Labs: Metal and Nr Essay

activity series of metals introduction: Alloy: An alloy is a mixture or metallic solid solution composed of two or more elements. Alloying a metal is done by combining it with one or more other metals or non-metals that often enhance its properties. For example, steel is stronger than iron, its primary element. The physical properties, such as density, reactivity. The term alloy is used to describe a mixture of atoms in which the primary constituent is a metal. The primary metal is called the base…

Essay about Materials and Processes, Chap. 8 Review

process. 3. Draft or taper 4. When metal solidifies from liquid it shrinks in inches/feet depending on metal. You have to leave enough extra metal to allow for shrinkage and machining. 5. Cores are the center (void) of a part. Used to produce a desired cavity. Mostly by compacting a sand mixture into the core box and curing it. 6. A crane hook needs to be able to safely handle a lot of weight, so I would use steel because it is stronger than cast iron and cast iron is a lot more brittle. 7. I would…

The History of Iron Essay

Iron is a chemical element with the symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is the most common element (by mass) forming the planet Earth as a whole, forming much of Earth's outer and inner core. It is the fourth most commonelement in the Earth's crust. Iron's very common presence in rocky planets like Earth is due to its abundant production as a result of fusion in high-mass stars, where the production of nickel-56 (which decays to the…

Oxygen and Manganese Dioxide Essay

below. In the extraction of iron in the blast furnace, a mixture of iron ore, coke (form of carbon) and limestone is used. The overall reaction is: Fe2O3(s) + 3CO(g) 2Fe(s) + 3CO2(g) 1. What is the function of the limestone in the extraction process? a) It acts as a catalyst in the reaction. b) Its decomposition at high temperatures provides the calcium oxide and carbon dioxide needed for the extraction process. c) It forms a layer of slag over the iron to prevent its oxidation. d)…

Stoich Lab Essay

Stoichiometry of Reaction of Iron with Copper (II) Sulfate Solution Objective To demonstrate the use of stoichiometric principles in order to verify the correct chemical equation of the reaction between iron metal and a solution of copper (II) sulfate. Theory Stoichiometry is a branch of chemistry which deals directly with the law of definite proportions and also the conservation of mass and energy to chemical activity. In the experiment the reaction between iron metal and copper (II) sulfate is…

Essay about Recycling Steel

recycling became important in American society and in many other parts of the world. Economic depressions made recycling a necessity for many people to survive, as they couldn't afford new goods. In the 1940s, goods such as nylon, rubber and many metals were rationed and recycled to help support the war effort. However, the economic flourishing of the postwar years caused conservationism to fade from the American consciousness. It wasn't until the environmental movement of the 1960s and 70s, heralded…

Electrochemistry and Oxidation Essay

reduction came to be associated with producing metals from their compounds. Red iron (III) oxide “reduced” by carbon monoxide gas to iron metal is a typical example of this process. 3 common metallurgical processes Fe2O3(s) + 3 CO (g) (reducing agent) → 2 Fe(s) + 3 CO2 (g) SnO2(s) + C(s) (reducing agent) → Sn(s) + CO2 (g) CuS(s) + H2 (g) (reducing agent) → Cu(s) + H2S (g) * A reducing agent causes the reduction of a metal compound to an elemental metal * Corrosion reactions are similar to combustion…
