Aluminium cost a mere $2/kg in the refined, ready to use state. It is actually cheaper than many so called "cheap" polymers.
And diamond itself is also quite cheap to synthesize industrially if you don't need high-purity or large crystals. That's why diamond cutting tools cost only a few bucks.
I think the OP's point is that aluminum is not as cheap to process as plastics. Don't know if it's true, though.
