Aluminum is just not that expensive. Aluminum is even easy to cast and
machine. And, I for one, would pay the additional cost of having a metal
cabinet ... but we remain stuck with plastic junk ... I have gotten rid
of all my old metal radios, the old tubers and transistor rigs. I miss
the cabinets though ... I am surprised China doesn't catch on that a
radio in an aluminum cabinet would take the country by storm. They,
certainly, could manufacture it cheap enough.

Aluinum corrodes. You need to use more expensive alloys to beat the
longevity of plastic in the real world.
