When the earth formed, the molten mass contained a variety of metals, which we extract and use in massive quantities today. When molten, the majority of metals combine with a rock to form metallic ores. The most common of these are bauxite, which is used to extract aluminum, and iron ore, which is used to extract iron. Today, over seventy different metals are extracted and used in manufacturing.
Certain metals, such as copper and lead, can be used in their pure state to maximize their inherent properties. However, alloys are frequently formed by combining different metals or metals with other materials. By creating alloys, we can tailor the properties of metal to our specific requirements. A pure metal is a substance composed entirely of atoms of a single metallic element, for example, aluminum, gold, copper, lead, or zinc. Most metals occur in their pure form very rarely, if ever, in nature and must therefore be extracted from metal ore.
Numerous metals possess extremely advantageous properties, such as being excellent conductors of electricity. On the other hand, the majority of metals are too soft and malleable to be used in their pure state. Rather than that, they are combined with other metals or non metal elements to create much harder and stronger alloys while retaining many of the original metal's properties. Alloys include steel, which is composed of iron and carbon, and bronze, composed of copper and tin.
Ferrous metals are composed of iron and are renowned for their tenacity. Consider the following materials: steel, stainless steel, carbon steel, and cast iron. Ferrous metals are used in various architectural and industrial applications, including skyscrapers, bridges, vehicles, and railroads.
Ferrous metals are also used in appliances and engines due to their magnetic properties. Ferrous metals also contain a high amount of carbon, which makes them prone to rust. The exceptions are stainless steel, chromium, and wrought iron, which contains a high percentage of pure iron.
Ferrous metals include the following:
● Steel is a combination of iron and carbon; it is extensively used in construction and industrial metal fabrication.
● Carbon steel: Iron with a high carbon content; tough metal.
● Stainless steel is an alloy steel that has been treated with chromium to make it resistant to rust.
● Other alloy steels: Metals such as chromium, nickel, and titanium are added to other metals to strengthen them without adding weight.
● Cast iron is composed of iron, carbon, and silicon; it is a dense, hard metal that is resistant to wear.
Since the Copper Age, around 5,000 B.C. non-ferrous metals have been used. The absence of iron in non-ferrous metals is typically more corrosion resistant than ferrous metals. Aluminum, aluminum alloys, and copper are all examples of non-ferrous metals that are frequently used in industrial applications such as gutters, roofing, pipes, and electrical.
Brass, gold, nickel, silver, tin, lead, and zinc are also non-ferrous metals. Non-ferrous metals also have the properties of being non-magnetic, malleable, and lightweight. As a result, they are well-suited for use in aircraft and other applications.
Non-ferrous metals include the following:
● Aluminum is alight weight, low-strength material that is easily shaped.
● Copper is a highly malleable metal with high conductivity.
● Lead is a dense, malleable metal with a low melting point and low strength.
● Tin: A soft, malleable metal with a low tensile strength that is frequently used to coat steel to prevent corrosion.
● Zinc is a medium-strength metal with a low melting point frequently used in galvanizing to protect iron or steel from rust.
Physical properties of typical pure metals include the following:
● Ductile- ductile material that can be drawn into a fine wire
● Malleable—can be beaten into thin sheets without cracking.
● Lustrous- when polished, acquire a sheen
● Significantly high melting and boiling points
● Excellent heat and electricity conductor
The arrangement of atoms in pure metals reflects these properties. Because pure metal is composed of only one type of atom, all of its atoms are the same size. Because all atoms are the same size in the solid-state, they are ordered and closely packed together. As a result, pure metals have a very high density. Metal atoms are organized in layers to form a three-dimensional crystal lattice. Due to the powerful forces of attraction between the closely packed atoms, metals have high melting and boiling points. As a result, more heat energy is required to overcome the attraction forces.
While the forces of attraction between the atoms are solid and pure metals are weak and soft due to their ductility and malleability, they have limited applications.
Pure metals are malleable and soft due to the uniform size and arrangement of their atoms; as a result, the layers of atoms slide over one another easily when a force is applied. Pure metals are malleable, brittle, and malleable. They can be shaped. This is because pure metals contain some empty spaces between their atoms. When a metal is knocked or pressed, groups of atoms may slide and settle into new positions.
Due to the ductility and malleability of pure metals, they are relatively soft and easily oxidized to form metal oxides.Alloys are created to enhance the properties of pure metal.
