'Voltage' isn't 'conducted'. Voltage can be thought of as 'electrical pressure' which, when applied across opposite ends of a conductor will cause a CURRENT to flow along that conductor.
So your question should really be asking, why aluminium conducts a greater CURRENT than iron.
The answer is simple. Aluminium is a better 'conductor' than iron. In other words iron resists the flow of current more than aluminium does. Or to express this in another way, iron offers a greater RESISTANCE to the flow of current.
Resistance is a natural property of a conductor, with some conductors have more, or less, resistance than other conductors. The best conductor, i.e. the one with the least resistance, is silver -closely followed by copper. Iron is a relatively poor conductor in comparison with silver, copper, or aluminium.

Which 2 metals can only be extacted by electrolysis?
They are aluminum, calcium, magnesium, and sodium.
What is the symbol for sodiumironaluminum and helium?
The symbol for sodium is Na, for iron it is Fe, for aluminum it is Al, and for helium it is He. Sodium, iron, and aluminum are elements on the periodic table, while helium is a noble gas. If you're looking for a combined symbol for sodium, iron, aluminum, and helium together, it would be NaFeAlHe.
Is there aluminium in bi-carbonate of soda?
No. bicarbonate of soda (sodium bicarbonate) is made of sodium, hydrogen, carbon, and oxygen.
What element conducts electricity cadmium or sodium?
I believe you ment to say 'which element conducts electricity Cadmium or Sodium?'They both do. They are both metals.
Is sodium azide a good conductor of electricity?
Not in it's usual solid state. But sodium chloride will conduct electricity of molten or dissolved in water.
Is aluminum a better conductor than sodium?
Yes..Aluminium has a larger charge (more electrons) and the electrons cloud are more compress to the nucleus (small atomic radius) compared to Sodium. So the density of Aluminium is larger and this leads to better conductivity of electricity.
How is aluminum and sodium different from each other?
There are so many ways they are different: 1. Sodium is more reactive than aluminium. 2. Sodium is softer than aluminium. 3. Aluminium conducts electricity better than sodium. ...
Is aluminum more electronegative than sodium?
Aluminum is more electronegative than sodium. The electronegativity of aluminum is 1.61. The electronegativity of sodium is 0.93.
What is Sodium aluminum silicate in pharmaceutical use?
sodium aluminum silicate is used as antacid in pharmaceutical and they formed a paste or gel for sodium aluminum silicate
Is sodium the best conductor of electricity?
While sodium is a good conductor of electricity, it is not the best conductor. Metals like copper and silver are better conductors of electricity due to their higher number of free electrons that can easily carry electric current. Sodium is still used as a conductor in some applications, especially in sodium-vapor lamps.
Will sodium sulfate react with aluminum?
No, sodium sulfate does not react with aluminum. Sodium sulfate is a neutral salt and does not possess the capability to corrode or react with aluminum metal.
Is sodium aluminum silicate organic?
No. To be considered organic a compound must contain carbon. Sodium aluminum silicate contains sodium, aluminum, silicon, and oxygen, but not carbon.
Does sodium bicarbonate or baking soda contain aluminum?
No. Sodium bicarbonate only contains sodium, carbon, hydrogen, and oxygen.
Which element has the fewest protons carbon aluminum sodium or oxygen?
Aluminum has the fewest protons among carbon, aluminum, sodium, and oxygen. Aluminum has 13 protons, while carbon has 6, sodium has 11, and oxygen has 8 protons.
What is the formula for aluminium and sodium?
Aluminum is AL sodium is NA
What reaction occurs when solutions of aluminum chloride and sodium hydroxide are mixed?
When solutions of aluminum chloride and sodium hydroxide are mixed, a white precipitate of aluminum hydroxide is formed, along with the production of sodium chloride. This is a double displacement reaction where the aluminum ions in aluminum chloride switch places with the sodium ions in sodium hydroxide.
What has the higher melting point sodium chloride or aluminum oxide?
Aluminum oxide has a higher melting point than sodium chloride. Aluminum oxide has a melting point of around 2072°C, while sodium chloride has a melting point of 801°C.
