Should be iron.
Explanation:
Since the theoretical black dwarf is just a white dwarf that has cooled completely, then it should be the same composition as a white dwarf. The final end product of fusion is iron, therefore a black dwarf would be made of iron. Extremely dense iron since gravity would have squished it all together in one mass of subatomic particles, but iron non the less.
