The term metal comes from the Greek language where it translates to quarry or mine in the English language. Generally, metals are good conductors of both electricity and heat. These materials are malleable and ductile. Being malleable means that they can be hammered into sheets while ductility means that they can be drawn into wires. Metals can be alloys or chemical elements such as stainless steel and iron respectively. Here are facts regarding AZ metals.
The meaning of the word metal varies depending on the subject being considered. For example, the term might be used to refer to any element that can conduct electricity at absolute zero temperature in Physics. Most elements and compounds that are not considered as metal generally are often metallic when put under high pressure levels. Iodine is a good example because it becomes metallic when put under levels of pressure ranging from 40 to 170 times that of the pressure of the atmosphere.
The earth crust comprises of 25 percent of metal. Metal is very common in nearly all aspects of life because of its abundance. Various metals have dissimilar properties and this is the reason for some being more useful than others. In general, a lot of strength and resilience is exhibited by metal. This strength makes them to find use in the building of high-rise structures and bridges.
Products that are made from metal include aircraft, furniture, pipes, tools, home appliances, stationery, utensils, vehicles and many more. Coinage used to be made from precious metal in the old days but that is not the case anymore. Twenty three more elements on the periodic table are used to make coinage.
The use of copper is often thought to be the beginning of the history of metal. This happened some 11 thousand years ago. The use of bronze was introduced in the 5th millennium BCE. Before bronze was introduced, other metals such as lead, brass, iron, gold, and silver were already in use. Early forms of steel were then invented before sodium was discovered in 1809 as the first light metal.
More sophisticated alloys started to be produced and used in most processes and products after world war two. Alloys are usually described as substances that are composed of more than one element whereby one is a metal. Usually, they contain metallic properties. The composition might be variable or fixed. This depends on the chemical elements used in making the alloy.
There are several reasons why it is important to make alloys for use. One of these reasons is that metal in its pure form tends to be too brittle, soft, or chemically reactive to be put to any practical use. When different ratios of metals are combined, their properties are modified to achieve desirable characteristics. The reason why alloys are made is to make them harder, corrosion resistant, and less brittle.
More desirable colors and lusters are contained in alloys than in pure metal. Although many alloys are being used today, those of iron are the most abundant. Their commercial use and quantity are used to measure their abundance. Some of the popular alloys of iron are carbon steel, stainless steel, cast iron, alloy steel, and tool steel.
