What is aluminium copper used for?
Copper and aluminium are most frequently used as the electrical conductors in electrical cables due to their low resistance and excellent conductivity.
What are the 4 main properties of aluminium?
It has low density, is non-toxic, has a high thermal conductivity, has excellent corrosion resistance and can be easily cast, machined and formed. It is also non-magnetic and non-sparking. It is the second most malleable metal and the sixth most ductile.
What is the formula of aluminum copper?
The aluminium chemical formula is Al. The molar mass is 26.98g/mol. Metallic aluminium is present in its elemental state (the most fundamental form is the elemental form, which is expressed in the periodic table). Since Aluminium’s atomic number is 13, we get the formula 2(n2) using.
What happens when you mix aluminum and copper?
When copper and aluminum are heated to 550 degrees Celsius (1,022 degrees Fahrenheit), solid copper will dissolve in the aluminum, forming a solution. At this temperature, the copper-aluminum solution can contain up to 5.6 percent copper by weight. This solution is saturated; it can hold no more copper.
What are the properties of copper?
It is malleable, ductile, and an extremely good conductor of both heat and electricity. It is softer than zinc and can be polished to a bright finish. It is found in group Ib of the periodic table, together with silver and gold. Copper has low chemical reactivity.

Can you alloy copper and aluminum?
Copper and aluminum can be combined to form a copper-aluminum alloy. An alloy is a mixture, and therefore does not have a chemical formula. However, under very high temperature, copper and aluminum can form a solid solution.
