Can I mix HG series sprockets?

No, this is not recommended.
Every cassette has a group indication on the sprockets (for example AU-, S-, T-group etc.)

When replacing the individual sprockets, always pay attention that the correct group marking is used.
When a different group mark is used, the optimum HG performance cannot be achieved, which may result in slow and noisy shifting and may have a bad influence on the chain durability.
