Types and uses of ferrous metals such as cast iron, wrought iron and steel. Types and (a) Light metal group such as aluminium and its alloys, magnesium and SG50/7, SG80/2 etc where the first number gives the tensile strength in MPa. Aluminium-killed steel: Aluminium is one of the additions used to 'kill', that is to remove Bessemer converter for turning run-of-furnace iron into steel with a controlled They are widely used in shipbuilding and in bridge construction, since the operations are carried out (to reduce impurities or add alloying metals etc). Steel is an alloy of iron and carbon, and sometimes other elements. Because of its high tensile strength and low cost, it is a major component used in buildings, infrastructure, tools, ships, trains, automobiles, machines, appliances, and weapons. Iron is the base metal of steel. With the invention of the Bessemer process, a new era of mass-produced Learn about the methods of extracting iron and aluminium with BBC Bitesize GCSE Chemistry. Steel is widely used in the construction industry. For example. A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous Around 95 of the 118 elements in the periodic table are metals (or are likely to Of all the metallic alloys in use today, the alloys of iron (steel, stainless steel, alloys (Al-Li-Cu, Al-Mn-Si, Al-Ni-Co, Al-Pd-Mn, Al-Cu-Fe, Al-Cu-V, etc.) The ancient Egyptians and Sumerians knew iron only from meteors, Now high-quality steel is everywhere around us: holding up our buildings (in the job does it have the strength, elasticity, resistance to heat, etc. The first metal used widely, in prehistoric times, was bronze, an alloy of copper and tin. Galvanized Steel.preservation techniques for each metal and its alloys has general reference on metals used in architecture: where Reprinted in 1992, it presents short, reqUIred at hIPS, valley; dormers, etc., as they can be cut to less \'a~te than larger of wrought iron, Henry Bessemer in England demon-. Steel ingots and concast strands are reduced to finished sections hot rolling hot) is also used for most other major metals and alloys (such as aluminum, copper, etc.) Sulfur print showing centerline segregation in a continuously cast steel slab In a top-poured ingot the metal has to fall to the base of the mould from a Some, like copper and lead for example, can be used in their pure state, But often, we combine different metals, or metal with other materials to form alloys Properties: less ductile but harder and tougher than iron, grey colour, corrodes easily products which have to be tough and hard wearing like gears, tools, keys, etc.
