Duralumin (also called duraluminum, duraluminium, duralum, dural (l)ium, or dural) is a trade name for one of the earliest types of age-hardenable aluminium–copper alloys. The term is a combination of Dürener and aluminium. Its use as a trade name is obsolete. Today the term mainly refers to aluminium-copper alloys, designated as the 2000 ...
2024 aluminium alloy is an aluminium alloy, with copper as the primary alloying element. It is used in applications requiring high strength-to-weight ratio, as well as good fatigue resistance. It is weldable only through friction welding, and has average machinability. Due to poor corrosion resistance, it is often clad with aluminium or Al-1Zn ...
Duralumin is the oldest variety in this group and goes back to Alfred Wilm, who discovered it in 1903. Aluminium could only be used as a widespread construction material thanks to the aluminium-copper alloys, as pure aluminium is much too soft for this and other hardenable alloys such as aluminium-magnesium-silicon alloys (AlMgSi) or the ...
7075 aluminium alloy ( AA7075) is an aluminium alloy with zinc as the primary alloying element. It has excellent mechanical properties and exhibits good ductility, high strength, toughness, and good resistance to fatigue. It is more susceptible to embrittlement than many other aluminium alloys because of microsegregation, but has significantly ...
Like duralumin, this was a 4% copper alloy, but with the addition of 2% nickel and 1.5% magnesium. [4] This addition of nickel was an innovation for aluminium alloys. These alloys are one of the three main groups of high-strength aluminium alloys, the nickel–aluminium alloys having the advantage of retaining strength at high temperatures.
The Duralumin alloys had already demonstrated high-strength aluminium alloys. Y alloy's virtue was its ability to maintain high strength at high temperatures. R.R alloys were developed by Hall & Bradbury at Rolls-Royce, [3] partly to simplify the manufacture of components using them. A deliberate heat treatment process of multiple steps was ...
An aluminium alloy ( UK / IUPAC) or aluminum alloy ( NA; see spelling differences) is an alloy in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin, nickel and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are ...
Electrical properties. Volume resistivity (ρ) 32.5–39.2 nOhm·m. 6061 aluminium alloy ( Unified Numbering System (UNS) designation A96061) is a precipitation-hardened aluminium alloy, containing magnesium and silicon as its major alloying elements. Originally called "Alloy 61S", it was developed in 1935. [ 2]
