What's the material of the A1200's case ?

It is plastic, noone knows the specifics.

You can try to 'melt' it back onto the case with acetone, but be careful and try it somewhere on the inside beforehand to be sure it works.

@Jose
If you find the right glue you can glue a small plate onto the inside of the case holding the broken off part in place without showing the gap to much by adding glue to it.
Melting would come to mind again, if the afore mentioned plate is of metal.

Nooo!

These are new cases, without the bromide included to the composition of the plastic in the past that causes yellowing and crumbling of those old cases nowadays.

It might still be some kind of ABS, but certainly not the same as the original ones.
