As with all of the platinum group metals, iridium can be found naturally in alloys with raw nickel or raw copper.

The single crystal nickel alloy turbine blades are also hollow, and air is pushed through laser drilled holes in them to cool them because the gas temperature is higher than the melting point of the blades.

Alloyed steels, which are sometimes also called special steels and may be considered specialty products, contain small portions of alloying elements such as chromium, cobalt, manganese, molybdenum, nickel, niobium, silicon, tungsten or vanadium.

After its discovery, the only source for nickel was the rare Kupfernickel but, from 1824 on, nickel was obtained as a byproduct of cobalt blue production.

New Caledonia's economy is dominated by the nickel industry.

Fe2 and Mg2 may substitute for Ni in trevorite.

In 1810, he observed the magnetic properties of nickel and cobalt.

In the nickel and copper deposits, the platinum group metals occur as sulfides (i.e.

These catalysts must be highly active, stable, and, for global scalability, composed of earth abundant elements, such as iron, nickel, or cobalt, not the scarce metals now used, such as ruthenium or iridium.

The reaction plays a key role in the order and decomposition of quasicrystalline phases in several alloy types.

Nickel is very soluble in ferrite therefore, it forms compounds, usually Ni3Al.

Nickel 58 is the most abundant isotope of nickel, making up 68.077 of the natural abundance.

The United States imports an average of 130,000 tons of raw nickel per year.

Copper, nickel, and other metals are also common, but in lower denominations.

The discovery of the large deposits in the Sudbury Basin, Canada, in 1883, in Norilsk Talnakh, Russia, in 1920, and in the Merensky Reef, South Africa, in 1924 made large scale production of nickel possible.

The degenerate explosion model predicts the production of about a solar mass of nickel 56 (56Ni) by the exploding star.

Alloyed steels account for a relatively small portion of all finished steel products, and their production and use are concentrated in developed countries and China.

Certain grades of steel are sensitive to the 78 nitrogen which was part of the air blast passing through the steel.

Iron artifacts, composed of meteoric iron, have the chemical composition containing up to 40 nickel.

Significant natural resources are iron ore, coal, potash, timber, lignite, uranium, copper, natural gas, salt, nickel, arable land and water.

The three provinces have each signed up to acquire a total share of 10 per cent in Goro Nickel.

New Caledonia has benefited from higher global nickel prices in 2004, partly as a result of strong demand from China.

The debate over the impact that new nickel projects will have on New Caledonia's pristine maritime environment began some years ago.
