Aluminum is one of the major engineering materials and has wide varieties of application in modern technology (Starke and Staley 1996; Komatsu et al. 1991; Skillingberg and Green 2007).Although pure Al is a good conductor for electricity and heat, it is a very soft material which restricts its application in engineering fields that demand high mechanical strength.
The application of copper as a conductor has a history of over 200 years since its discovery and application in the late 18th century with electricity.. Aluminum, as a young metal, was called "silver gold" in the mid-19th century, even more precious than gold. It was not until 1886 that American scientist Hall independently researched and developed the electrolytic …
As already mentioned, aluminium–copper alloys belong to the family of high-strength materials, but unfortunately, compared to aluminium alloys of the 6xxx series, they offer much lower corrosion resistance. Numerous studies show that copper as an alloying element has a detrimental effect on the corrosive properties of aluminium, it especially reduces the …
Although the content of aluminum in Al73Cu5Fe22 is a little higher than Al7Cu2Fe, the main phase of cast Al73Cu5Fe22 is Al60Cu30Fe10, which is different from Al7Cu2Fe in Al7Cu2Fe alloy in figure 1 (b). There are some AlCu and a small amount of Al6.35Cu2.4Fe1.25, Al76.8Fe24, Al23CuFe4 and Al13Fe4 in the Al73Cu5Fe22 alloy. Heat treatment and mechanical milling …
In this paper, two ternary aluminum alloy, Al7Cu2Fe and Al73Cu5Fe22 were prepared. The main phase of Al7Cu2Fe alloy was Al7Cu2Fe. The heat treatment increased the proportion of Al7Cu2Fe. The main ...

In order to accommodate the same circuit ampacity, you typically need to upsize your conductor by two sizes, for example, by substituting a 750 MCM aluminum wire for a 500 MCM copper wire. This is because aluminum wire requires a larger volume to conduct the same amount of electricity as copper does. Wire made of aluminum is incredibly light ...
At the same time excess electrons move from the aluminum to the copper through the ammeter. This flow creates the current and causes the needle to move. 2Al ==> 2Al 3+ + 6 e- -3.32 volts 3Cu2+ + 6e- ==> 3Cu -1.02 volts If you disconnect the ammeter and leave your hands on the plates, electrons pile up in the aluminum, and this pile up will create a voltage. This can be …
