Inco

Inco is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Inco rather than just read about it. In short: Inco Limited was an American-Canadian mining company that existed from 1902 to 2007. The company was founded as a New Jersey corporation in 1902 as the International Nickel Company by Robert Means Thompson and J.

Key takeaways

  • Inco belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Inco to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Inco from memory before moving on to harder problems.

Reference excerpt

Inco Limited was an American-Canadian mining company that existed from 1902 to 2007. The company was founded as a New Jersey corporation in 1902 as the International Nickel Company by Robert Means Thompson and J. P. Morgan. In 1916, the company created a Canadian subsidiary, the International Nickel Company of Canada Limited, which in 1928 took over the American parent. In April 1976, International Nickel changed its name to Inco Limited. Inco was one of Canada's largest corporations and one of the world's largest nickel producers. In late 2006 the company was acquired by Vale of Brazil, and in 2007 became Vale Canada.

History

Founding of Inco The company was founded following the discovery by blacksmith Tom Flanagan in Copper Cliff, Ontario of chalcopyrite deposits, while the Canadian Pacific Railway was being built in 1883; the township of Sudbury soon followed in 1884 when JL Morris, provincial land surveyor, laid it out. Initially, ore was shipped for smelting to a plant in Constable Hook, New Jersey, owned by the Orford Copper Company. Processing revealed in 1884 that the ore was also rich in nickel and exploration tests revealed an enormous potential. In 1893 Robert M. Thompson patented the Orford "Tops and Bottoms" process; this was the first commercially viable method of separating (Fe,Ni)9S8 Pentlandite-borne Nickel from the CuFeS2 Chalcopyrite-borne Copper. The Spanish-American War focused the eyes of the world on nickel steel, because in the Battle of Manila Bay and the Battle of Santiago de Cuba, the American losses were negligible while the Spanish losses were catastrophic. This was the result of the nickel steel used by the Americans to clad their hulls. The Spanish Navy had ignored to their peril the 1889 paper by James Riley, "Alloys of Nickel and Steel", and the market for nickel was made. The next year saw the introduction by Bethlehem Steel of a virtually indestructible nickel steel automobile axle. Nickel mining started in Sudbury, Ontario in 1902, and that year, the International Nickel Company, Ltd. was created by Thompson and John Pierpont Morgan in New York, NY as a joint venture between Canadian Copper Company, Orford Copper Company, and American Nickel Works, with a capitalization of $28 million. In 1905, Monel alloy was discovered by Robert Crooks Stanley (1876-1951) and named for Inco President Ambrose Monell. Meanwhile, the development of austenitic stainless steel was launched by a pair of Krupp engineers known today as AISI Type 304 or simply 18/8, which indicates a nickel content of 8%. This novelty would assure the 20th-century success of the firm. In 1916, the International Nickel Company of Canada, Ltd. was incorporated in Copper Cliff in Sudbury; this entity was a subsidiary of New York-based Inco. The company built a new refinery in Port Colborne in 1918 and during the following year, the company first began using the trade name Inco. During the 1919 Ontario general election, The Toronto World pursued a simmering scandal from 1916 concerning Inco and alleged provincial support of wartime shipments of the metal to Germany via the cargo submarine Deutschland. On 31 October 1928 the Canadian body corporate and its American parent switched roles and the Canadian became the parent. On 1 January 1929 the corporation acquired the British-owned Mond Nickel Company in exchange for treasury shares, to solve the Frood Mine problem. By 1931, Stanley had progressed to President of the firm. Between 1935 and 1939, sales exceeded 200 million pounds annually, which was more than 80% of world consumption. A significant proportion of these sales found their way to the United States, with other notable markets including the Soviet Union, Great Britain, Japan, and Germany. Approximately 9 percent of company's total sales from 1934 to 1939 were to Nazi Germany, mainly to meet the growing demand of the country's armaments industry.

Worked examples

Example 1 — a first encounter with Inco

Start with the simplest possible case. Write down what Inco claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Inco before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Inco ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Inco

In research
Inco appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Inco in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Inco is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1902 establishments, 1916 establishments, 2007 disestablishments, so understanding it makes those chapters shorter.
In everyday life
Look for Inco outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
