Nah I just happend to know that the guy who used to produce titanium coated magnetic implants had to stop somewhere around 9 months before the release of the iphone 15 cause the capacity of the company he contracted with for the coating was used up and every other vendor he tried as well. Its not about the titanium itself but rather the ability to work with it for implants in concerned about. I figured it was related to apple as they have very high standards. I can find the source on the implant if anyone is interested iirc its called the titan.
