Full Title

Full titles differ between systems:

IPC:

Changing the physical structure of non-ferrous metals or alloys by heat treatment or by hot or cold working > of aluminium or alloys based thereon

CPC:

Changing the physical structure of non-ferrous metals or alloys by heat treatment or by hot or cold working (apparatus for mechanical working of metal B21, B23, B24) > of aluminium or alloys based thereon

IPC and CPC are identically structured here. All 5 subcodes exist in both systems.

IPC defines codes here since 1985.
