Nikel (Russian: Ни́кель, lit. nickel; Finnish: Nikkeli) is an urban locality (an urban-type settlement) and the administrative center of Pechengsky District of Murmansk Oblast, Russia, located on the shores of Lake Kuets-Yarvi 196 kilometers (122 mi) northwest of Murmansk and 7 kilometers (4.3 mi) from the Norwegian border on E105.
Nickel is preeminently an alloy metal, and its chief use is in nickel steels and nickel cast irons, in which it typically increases the tensile strength, toughness, and elastic limit. It is widely used in many other alloys, including nickel brasses and bronzes and alloys with copper, chromium, aluminium, lead, cobalt, silver, and gold ( Inconel ...

A nickel is a five-cent coin struck by the United States Mint. Composed of 75% copper and 25% nickel, the piece has been issued since 1866. Its diameter is.835 inches and its thickness is.077 inches. Due to inflation, the purchasing power of the nickel continues to drop, and currently the coin represents less than 1% of the federal hourly minimum wage. In 2018, over 1.26 billion nickels were produced at the Philadelphia and Denver mints. The silver half dime, equal to five cents, had been issued
The silver half disme was one of the denominations prescribed by the Mint Act of 1792; its weight and fineness were set by law. The first pieces under federal authority were half dimes, struck in 1792 in the cellar of John Harper, a saw maker; as the first federal mint was still under construction in Philadelphia, this took place locally at Sixth and Cherry Streets. The dies were engraved by Adam Eckfeldt, who a half-century later recalled that the silver for the half dimes was supplied by Presi
The Civil War caused most American coins to vanish from circulation, with the gap filled by such means as merchant tokens, encased postage stamps, and United States fractional currency, issued in denominations as low as three cents. Although specie was hoarded or exported, the copper-nickel cent, then the only base metal denomination being struck, also vanished. In 1864, Congress began the process of restoring coins to circulation by abolishing the three-cent note and authorizing bronze cents an
In anticipation of the approval of the new five-cent coin, the Mint's chief engraver, James B. Longacre, had begun preparing designs and pattern coins in 1865. After rejecting pieces showing deceased presidents George Washington and Abraham Lincoln, Treasury Secretary Hugh McCulloch decided on a design similar to Longacre's two-cent piece, with a shield on the obverse and a numeral 5 surrounded by stars and rays on the reverse. This has come to be known as the Shield nickel. The new coins proved
With production of nickels lagging in the late 1870s, and with minimal strikings of the copper-nickel three-cent piece, Wharton sought to increase the use of nickel at the Mint. The bronze cent represented a major portion of the Mint's production, and Wharton began to lobby for the piece to be struck in copper-nickel, as it had been from 1857 until 1864. In 1881, this lobbying led Philadelphia Mint Superintendent Archibald Loudon Snowden to order Mint Engraver Charles Barber to produce uniform d
President Theodore Roosevelt in 1904 expressed his dissatisfaction with the artistic state of American coins, and hoped to hire sculptor Augustus Saint-Gaudens to beautify them. Saint-Gaudens, before his death in 1907, designed a new eagle and double eagle, which entered circulation that year; the cent, quarter eagle, and half eagle were redesigned by other artists and were released into circulation by 1909. That year, Mint Director Frank Leach instructed Barber to make pattern coins for new nic

Nikel je jeden z piatich feromagnetických elementov. Ale napríklad „niklové“ mince v USA nie sú magnetické, lebo väčšinou obsahujú 75% medi. Kanadské medené mince razené v rozličných periódach v rokoch 1922 – 81 obsahovali 99,9 % niklu a boli magnetické.

Nikel adalah bahan magnetostriktif alami, artinya, jika ada medan magnet, bahan tersebut mengalami sedikit perubahan panjang. Magnetostriksi nikel sekitar -50 ppm, yang menunjukkan bahwa nikel berkontraksi. Nikel digunakan sebagai pengikat dalam industri semen wolfram karbida atau logam keras dan digunakan dalam proporsi 6% sampai 12% berat.
The Jefferson nickel has been the five-cent coin struck by the United States Mint since 1938, when it replaced the Buffalo nickel. From 1938 until 2004, the copper-nickel coin's obverse featured a profile depiction of founding father and third U.S. President Thomas Jefferson by artist Felix Schlag; the obverse design used in 2005 was also in profile, though by Joe Fitzgerald. Since 2006 Jefferson's portrayal, newly designed by Jamie Franki, faces forward. The coin's reverse is still the Schlag o
The design for the Buffalo nickel is well regarded today, and has appeared both on a commemorative silver dollar and a bullion coin. However, during the time it was struck, it was less well liked, especially by Mint authorities, whose attempts to bring out the full design increased an already high rate of die breakage. By 1938, it had been struck for 25 years, thus becoming eligible to be replaced by action of the Secretary of the Treasury rather than by Congress. The Mint, which is part of the
Production of the Jefferson nickel began at all three mints, on October 3, 1938. By mid-November, some twelve million had been coined, and they were officially released into circulation on November 15; more than thirty million would be struck in 1938. According to contemporary ac
When it became known that the Denver Mint had struck only 2,630,030 nickels in 1950, the coins began to be widely hoarded. Speculation in them increased in the early 1960s, but prices decreased sharply in 1964. Because they were so widely pulled from circulation, the 1950-D is re

The key deal was completed on June 28, 2007, when Norilsk Nickel acquired about 90 per cent of Canada's LionOre Mining International Ltd, the world's 10th-largest nickel producer at the time. This takeover, valued at US $ 6.4 billion, is the biggest acquisition abroad by a Russian company, making Norilsk Nickel the world's largest nickel producer.
