In addition to the quite different atomic structures of each:
Al is stiff and light weight
Cu is malleable and relatively heavy
Their natural colors are different as well: light grey for Al and dark reddish brown for Cu.
Gold, silver, copper, and aluminum are a few different metals.
Two materials are formed: metallic copper and aluminum chloride. This is an example of displacement of a less active metal from its compounds by a more active metal in the electromotive series.
When copper chloride and aluminum are combined, they react to form aluminum chloride and copper metal. This is a displacement reaction where aluminum replaces copper in the chloride compound.
Nothing will happen. Displacement reaction only happens when the element is more reactive than the salt solution. An example will be the otherwise. If you put aluminum metal into a solution of Copper (II) Sulfate. The aluminum metal will displace copper metal and you will have a solution of Aluminum Sulfate and copper metal. As long the element you put into the salt solution is more reactive than the cation of the solution, it will displace the metal.
Copper and Aluminum are metal elements that are good conductors.
When aluminum is dipped into copper sulfate solution, a single displacement reaction occurs. The aluminum displaces copper in the solution, forming aluminum sulfate and copper metal. This reaction is spontaneous and the copper metal will begin to precipitate out of the solution.

The reaction of aluminum with copper II sulfate solution is a redox reaction. Aluminum displaces copper from the copper II ion in the copper sulfate solution, forming aluminum sulfate and copper metal.
This reaction is an example of a displacement reaction, where aluminum displaces copper from copper (II) nitrate solution to form aluminum nitrate and copper metal. The copper metal appearing on top of the solution is a result of this displacement reaction.
When aluminum is added to copper sulfate, a displacement reaction occurs where aluminum displaces copper from the compound. This results in the formation of aluminum sulfate and copper metal. The reaction is exothermic and releases heat.
When aluminum foil is added to a solution of copper (II) chloride in water, a displacement reaction occurs where the aluminum reacts with the copper (II) ions. This results in the formation of aluminum chloride and copper metal. The copper metal will appear as a solid precipitate in the solution.
