Yes, it changed about a hundred years ago and has not change significantly
since then.

Actually, it has changed quite a bit. Different alloys, and something
called Glare which sandwiched aluminium/composites which yields
competitive weight/strength ratio to pure composites.

Glare is one of the things that made the Airbus A380 possible for instance.

Glare is 30 years old and has nothing to do with the production of aluminum
metal or 3D printing.

Aluminum alloys were first standardised in the 1930's and haven't changed much
since the 1950's


That's why there are all those aluminum alloy patents in the
1980s-1990s?
