They are reactive metals, and so need to be extracted from their ores using electricity, whereas less reactive metals like iron can be extracted by smelting - roasting with carbon - which is a lot cheaper to do.
Both metals are useful because they both do not corrode, as they both have an oxide layer to protect them from corrosion.
They both need to be extracted by a process called "electrolysis" which means to break up substances using electricity.
Electrolysis uses a lot of energy (ie- very high temperatures) and a great deal of electricity.
Therefore we need to recycle aluminium to conserve energy, as recycling aluminium does not require electrolysis.

Which is more expensive titanium or gold?
Gold is tremendously more expensive than titanium.
Is a resource that is too expensive to extract said to be economically depleted or limited?
limited
Is granite or sandstone more expensive?
Granite is more expensive as it is made under the earth (metamorphic rock) and harder to extract than sandstone which is a sedimentary rock
What elements are in titaium?
There are no elements in titanium. Titanium is an element. It's a chemical element with the atomic number 22.
Why is electrolysis needed to extract aluminum from its oxide?
The bond between the aluminum and its oxide is very strong. Aluminium is also high up in the reactivity series; using the displacement method requires highly reactive elements at high temperatures to extract the aluminum (not practical). You have to use electrolysis to extract aluminum because... Aluminium is higher than carbon in the reatvity series where carbon reduces the oxide from zinc iron tin etc.... so you need to use electrolysis to remove the oxygen from the aluminum ore. Hoped this help :)
Why was aluminium more expensive in the 1850s?
Aluminium is a reactive metal and so is hard to extract from it's compounds without modern technology.
Why does titanium more than steel?
i am doing homework and this is what i put: steel is extacted using a blast furnace which is quick and relatively cheap. however to extract titanium, magnesium is needed because it is more reactive. magnesium is extracted by electrolysis, which is expensive therefore it is not cheap to buy. you have to buy the magnesium to extract the titanium, which is why titanium is expensive hope this helped and you can copy it word for word i dont care :)
What will Substitutes and alternatives for aluminium?
One of the substitutes for aluminium is a titanium alloy, titanium is just as light but has a higher tensile strength than aluminium has.
How do you extract aluminium from Aluminium Oxide?
by using electrolysis
Which is the most reactive titanium aluminum or platinum?
Aluminium and titanium are about the same but aluminium is more reactive. platinum is the least reactive metal
What is the position of titanium in the reactivity series?
Titanium is placed between aluminium and magnesium.
What is the composition of type metal?
aluminium and titanium
Why aluminum-titanium alloy cannot be formed?
Not true; many titanium alloys contain aluminium.
What are solid made out of?
Aluminium Titanium Steel Brass
Why do you need electricity to make aluminium and titanium?
because we do
Do aluminium soda cans have titanium opening tabs?
NO.
Suggest why aluminium is more expensive than iron?
Aluminium is more expensive than iron because of its lower abundance in the Earth's crust. It is also more costly to extract and refine aluminium due to the energy-intensive process of electrolysis. Additionally, aluminium has a higher demand and is used in a wide range of industries which further contributes to its higher price.
