Equilibrium Phase Diagrams
Published in Joseph Datsko, Materials Selection for Design and Manufacturing, 2020
The common age-hardenable aluminum-copper alloys contain 5% or less copper. By heating them to 800–900°F, all of the copper is substitutionally dissolved in the solid α aluminum FCC structure. The age-hardening heat treatment, as described in Chapter 5, is a process wherein the second-phase θ is finely dispersed throughout the matrix as opposed to being a massive network around the α grains, as occurs during equilibrium cooling.
Casting and Foundry Work

Aluminum–copper alloys are characterized by their very high tensile strength-to-weight ratio. They are, therefore, mainly used for the manufacture of premium-quality aerospace parts. Nevertheless, these alloys have poorer castability than the aluminum–silicon alloys. Also, amounts of the copper constituent in excess of 12 percent make the alloy brittle. Copper additions of up to 5 percent are usually used and result in improved high-temperature properties and machinability.

Wrought aluminium alloys are also produced with a wide range of compositions. In the classification scheme adopted by many countries and described in BS EN 573, these are divided into eight series depending on the principal alloying element: 1000 series: ≥99% pure aluminium2000 series: aluminium–copper alloys3000 series: aluminium–manganese alloys4000 series: aluminium–silicon alloys5000 series: aluminium–magnesium alloys6000 series: aluminium–magnesium–silicon alloys7000 series: aluminium–zinc–magnesium alloys8000 series: miscellaneous alloys.

Aluminum has a distinct chemical composition of a combination of desirable characteristics. It’s one of the lightest metals on the globe. Approximately three times as featherweight as iron, but it is nonetheless rather powerful, extraordinarily flexible, and rust-resistant due to its surface being coated in a very thin yet extremely powerful which is coated with chromium sheet coating with high strength. It is nonmagnetic, having excellent electrical conductivity and it can make alloys with almost any other metals. Alloy nanoparticles are made up of two or more different metals, and aluminum is the most often used alloy, which is alloyed with magnesium, zinc, copper, silicon, and manganese, among other elements. With the addition of this chromium, lead, titanium, bismuth, and nickel are also produced, and Fe is generally present in trace amounts. Aluminum–copper alloys are mostly utilized in aircraft construction, where their low corrosion resistance plays a subordinate role. Structures of nanoparticles are given as in (Figure 2).
