The normal 13’s are still great phones. Good oled panels, a15! just inferior. if 7000 aluminium is better than SS, then why is the cheaper phone not using it? and the pro using 7k series aluminium? Because it isn’t better at all.
Because “marketing”. Apple are rather good at it. And ultimately, it’s easier to shine up. That’s probably the real reason it’s used.
Stainless is better at resisting corrosion mainly, not something a phone ever suffers from. Steel is harder, so it’s more resistant to dents, however the stainless Apple use is not of a very high strength, if they used the best stainless then it would be a different story. The coating is also a lot less durable than the aluminium frame coating.
7000 grade aluminium includes magnesium and copper to increase its strength and is used in the aviation industry. It’s the highest strength of any aluminium. Do you think they would make planes out of it if stainless was better?
Aluminium also costs more than stainless.
(The two types that are used by Apple)
Nobody has ever returned an iPhone because it’s too light, but many have because they are too heavy. If all specs were equal I would suspect people would opt for the lighter aluminium model over stainless.
