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.
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
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 ...
Cupronickel or copper–nickel (CuNi) is an alloy of copper with nickel, usually along with small quantities of other metals added for strength, such as iron and manganese. The copper content typically varies from 60 to 90 percent. (Monel is a nickel–copper alloy that contains a minimum of 52 percent nickel.)
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.
It mainly comes from iron-nickel meteorites that formed millions of years ago but were preserved from chemical attack by the vacuum of space, and fell to the earth a relatively short time ago. Metallic meteorites are composed primarily of the iron-nickel alloys: taenite (high nickel content) and kamacite (low nickel content). However, there are ...
L23A1 APFSDS: The penetrator is made from a tungsten–nickel–copper alloy with a 6 bladed aluminium fin and is located in a three-segment aluminium alloy saddle-type sabot. The shot 120mm TK APFSDS, L23 is used with the L8A1 charge.
