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
Copper–tungsten (tungsten–copper, CuW, or WCu) is a mixture of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure is therefore rather a metal matrix composite instead of a true alloy.
During the sintering process, the nickel diffuses into the tungsten, producing an alloy. Tungsten can also be extracted by hydrogen reduction of WF 6: WF 6 + 3 H 2 → W + 6 HF. or pyrolytic decomposition: [74] WF 6 → W + 3 F 2 (ΔH r = +) Tungsten is not traded as a futures contract and cannot be tracked on exchanges like the London Metal ...

The ignition is easier and the arc burns more stably than without the addition of thorium. For powder metallurgy applications, binders have to be used for the sintering process. For the production of the tungsten heavy alloy, binder mixtures of nickel and iron or nickel and copper are widely used. The tungsten content of the alloy is normally ...
Researches created an alloy with the strength of steel and the lightness of titanium alloy. It combined iron, aluminum, carbon, manganese, and nickel. The other ingredient was uniformly distributed nanometer-sized B2 intermetallic (two metals with equal numbers of atoms) particles. The use of nickel team avoided problems with earlier attempts ...
Nickel superalloy jet engine turbine blade. A superalloy, or high-performance alloy, is an alloy with the ability to operate at a high fraction of its melting point. [1] Key characteristics of a superalloy include mechanical strength, thermal creep deformation resistance, surface stability, and corrosion and oxidation resistance.
A bronze is an alloy of copper and other metals, most often tin, but also aluminium and silicon. Aluminium bronzes are alloys of copper and aluminium. The content of aluminium ranges mostly between 5% and 11%. Iron, nickel, manganese and silicon are sometimes added.
