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
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.
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.)
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 ...
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.
The alloy of 30% Ni, 0.8% Fe, 1% Mn and 68.2% Cu is used in maritime shipping, in particular for the manufacture of condenser tubes. Nickel gives melchior, unlike brass and bronze, a silver color, and that property, combined with its high corrosion resistance, made it popular for the manufacture of household utensils in the Soviet Union.

The nickel–copper sulfides resulting from the sulfur in its composition act as chip breakers, but because of these inclusions the surface finish of the alloy is not as smooth as that of alloy 400. Monel 405 is designated UNS N04405 and is covered by ASME SB-164, ASTM B-164, Federal QQ-N-281, SAE AMS 4674 & 7234, Military MIL-N-894, and NACE ...
