Italma
Italma (acronym of ''Italiano Alluminio Magnesio'') is an aluminium alloy. It was produced by A.S.A. (Alluminio Soc. Anonima) and was introduced shortly after World War II in order to being used in the new coinage of the Italian lira, which lasted until the adoption of the Italian euro coins in 2002. It comprised 96.2% aluminium, 3.5% magnesium, and 0.3% manganese.

Lira 1951
Lira is the name of several currency units. It is the current Turkish lira, currency of Turkey and also the local name of the Lebanese pound, currencies of Lebanon and of Syrian pound, Syria. It is also the name of several former currencies, including those of Italy, Malta and Israel. The term originates from the value of a Roman pound ( la, libra, about 329g, 10.58 troy ounces) of high purity silver. The Libra (weight), libra was the basis of the monetary system of the Roman Empire. When Europe resumed a monetary system, during the Carolingian Empire, the Roman system was adopted. The Roman denominations ''librae'', ''solidi'', ''denarii'' were used (becoming known in England as £sd). Particularly this system was kept during the Middle Ages and Modern Age in England, France, and Italy. In each of these countries the ''libra'' was translated into local language: pound (currency), pound in England, French livre, livre in France, ''lira'' in Italy. The Venetian lira was one o ...

Aluminium Alloy
An aluminium alloy (or aluminum alloy; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions. Cast aluminium alloys yield cost-effective products due to the low melting point, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4–13%) contribute to give good casting characteristics. Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required.I. J. Polmear, ''Light Alloys'', Arnold, 1995 Alloys c ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Italian Lira
The lira (; plural lire) was the currency of Italy between 1861 and 2002. It was first introduced by the Napoleonic Kingdom of Italy in 1807 at par with the French franc, and was subsequently adopted by the different states that would eventually form the Kingdom of Italy in 1861. It was subdivided into 100 ''centesimi'' (singular: ''centesimo''), which means "hundredths" or "cents". The lira was also the currency of the Albanian Kingdom from 1941 to 1943. The term originates from ''libra'', the largest unit of the Carolingian monetary system used in Western Europe and elsewhere from the 8th to the 20th century. The Carolingian system is the origin of the French ''livre tournois'' (predecessor of the franc), the Italian lira, and the pound unit of sterling and related currencies. In 1999 the euro became Italy's unit of account and the lira became a national subunit of the euro at a rate of €1 = Lit. 1,936.27, before being replaced as cash in 2002. History Etymology ...

Italian Euro Coins
Italian euro coins have a design unique to each denomination, though there is a common theme of famous Italian works of art from one of Italy's renowned artists. Each coin is designed by a different designer, from the 1 cent to the 2 euro coin they are: Eugenio Driutti, Luciana De Simoni, Ettore Lorenzo Frapiccini, Claudia Momoni, Maria Angela Cassol, Roberto Mauri, Laura Cretara and Maria Carmela Colaneri. All designs feature the 12 stars of the EU, the year of imprint, the overlapping letters "RI" for ''Repubblica Italiana'' (Italian Republic) and the letter R for Rome. There are no Italian euro coins dated earlier than ''2002'', even though they were certainly minted earlier, as they were first distributed to the public in December 2001. The choice of the design of the coins was left to the Italian public by means of a television broadcast where alternative designs were presented, letting the people vote by calling a certain telephone number. However, the 1 euro coin was missing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Magnesium
Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of the periodic table) it occurs naturally only in combination with other elements and it almost always has an oxidation state of +2. It reacts readily with air to form a thin passivation coating of magnesium oxide that inhibits further corrosion of the metal. The free metal burns with a brilliant-white light. The metal is obtained mainly by electrolysis of magnesium salts obtained from brine. It is less dense than aluminium and is used primarily as a component in strong and lightweight alloys that contain aluminium. In the cosmos, magnesium is produced in large, aging stars by the sequential addition of three helium nuclei to a carbon nucleus. When such stars explode as supernovas, much of the magnesium is expelled into the interstellar medium where it ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manganese
Manganese is a chemical element with the symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent; as a rubber additive; and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide. Manganese is also an essential human dietary element, important in macronutrient metabolism, bone formation, and free radical defense systems. It is a critical component in dozens of proteins and enzymes. It is found mostly in the bones, but also the liver, kidneys, and brain. In the human brain, the manganese is bound to manganese metalloproteins, most notably glutamine synthetase in astrocytes. Manganese was first isolated in 1774. It is familiar in the laboratory in the form of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
