Not Ross, but also an RN & a lab tech many years ago. You can sterilize aluminum, but the problems come up if something breaks through the anodizing. At that stage, it will begin to oxidize. Not horrible in functional terms for a razor, but not exactly a cosmetic enhancement.Yeah, I’m an RN. Were you guys able to sterilize anodized aluminum?
Regarding medical tools, most of the ones I can think of that are AL are designed for soft tissue applications (i.e., nasal/aural/vaginal specula, some probes, a variety of pre-silicone airway appliances). There is little likelihood of damage to the anodizing in these applications. Oxidation would create a microporus surface that could easily carry foreign material, or leave AlOx in the wound/incision, so things that could be cut, nicked, or abraded are SS.
