All aluminum pieces don't have to be annealed. I work for a company that produces aluminum hose fitting for the aeronautical industry and they are not annealed.

Could you specify the exact aluminum alloy you're using and the exact heat treatment condition you're trying to reach? There are dozens of alloys and dozens of heat treat conditions, and hundreds of combinations of both some possible on some alloys and not others.

This spans many standards and you've not provided enough information.

There is no blanket generic condition aeronautical parts need to be in, this is why the moniker 'aircraft grade aluminum' means absolutely nothing because there are MANY grades of aluminum that can and are used in an aircraft, and various conditions they work in will define the proper alloy and heat treatment for the specific usage.
