Nickel-based superalloys are used in load-bearing structures requiring the highest homologous temperature of any common alloy system (Tm = 0.9, or 90% of their melting point). Among the most demanding applications for a structural material are those in the hot sections of turbine engines (e.g. turbine blade). They comprise over 50% of the ...
The Joint European Torus and DIII-D tokamaks' vacuum vessels are made of Inconel. [43] Inconel 718 is commonly used for cryogenic storage tanks, downhole shafts, wellhead parts, [44] and in the aerospace industry -- where it has become a prime candidate material for constructing heat resistant turbines.

Working at Inco's Wiggin facility at Birmingham in the United Kingdom, Leonard Bessemer Pfeil is credited with the development of Nimonic alloy 80 in 1941, and used in the Power Jets W.2B. Four years later, Nimonic alloy 80A followed, an alloy widely used in engine valves today. Progressively stronger alloys were subsequently developed: Nimonic ...
It does not mean any metal that is rare, but rather strong in its characteristics. Exotic Materials are used for high performance tasks. Exotic Materials can include plastics, superalloys, semiconductors, superconductors, and ceramics. [1]

Quantities of niobium are used in nickel-, cobalt-, and iron-based superalloys in proportions as great as 6.5% [88] for such applications as jet engine components, gas turbines, rocket subassemblies, turbo charger systems, heat resisting, and combustion equipment. Niobium precipitates a hardening γ''-phase within the grain structure of the ...
Hiduminium or R.R. alloys (2% copper, iron, nickel): used in aircraft pistons; Hydronalium (up to 12% magnesium, 1% manganese): used in shipbuilding, resists seawater corrosion; Italma (3.5% magnesium, 0.3% manganese): formerly used to make coinage of the Italian lira; Magnalium (5-50% magnesium): used in airplane bodies, ladders, pyrotechnics ...
The use of pewter was widespread across Europe, from France to Norway and Britain (where most of the ancient tin was mined) to the Near East. [21] The alloy was also used in China and the Far East, arriving in Japan around 800 AD, where it was used for making objects like ceremonial vessels, tea canisters, or chalices used in shinto shrines.
