You can't make something that's unnaturally less durable (aluminum vs titanium) than something that is naturally durable but made more durable with configuration. Also writer intent. I'm sure he didn't write this with the intent of this being the tiniest of planets core which is the reason he wrote "the strongest of all".
Actually....
Mercury has the second densest core (after Earth):

And it's the smallest planet.
And you actually can - by compressing it. Fold a piece of paper enough and it will be thick enough to stop a bullet.
Diamonds are just coal, compressed. I can easily break a piece of coal - but compress it enough? And it becomes diamond, which I definitely can't break.
Earth's inner core, by the by, is only 1.7% of it's entire mass:

If a character moves the Earth (or it's equivalent mass) that's 50 times more mass.
Again - you can make things stronger by compressing it. Diamond is the hardest material of all, after all - but it's the same element as the graphite in a pencil.
