I haven't gone thru many and may probably update later but mixed_metal_ingot's crafting recipe doesn't.
Oddly enough, it tagged aluminum/titanium/etc but not bronze or brass.

Industrial Machine Frame/Casing doesn't support various Chrome plates but Titanium.
Tank units not supporting coal dusts and tungstens.
Probably every unique ore and alloy aren't supported.

I've fixed some recipes. Please, feel free to reopen with more examples.
