Correct, this isn’t mere casting. It is die casting, with really good surface finish (which matters for strength) and good tolerances once you iteratively take warpage into account.
And a big reason they didn’t use this in the past is you’d get bubbles which reduce strength dramatically. But improvements in process tech and ability to use X-rays to do fast, non-destructive evaluation allows near-forged material properties. Better than castings of years past.
