For those unaware aluminum bronze is an alloy of aluminum, copper, along with other trace metals and is characterized by being corrosion resistance, wear resistance, and strength. Sounds like the perfect material for safety razors and yet, I haven’t found any examples of razors being made out of this. Why do you think this is? P.S. Turns out there is also an alloy called aluminum brass which is similarly corrosion resistant but slightly less strong. I would ask the same question about this material as well.
Personally I like the color of polished bronze and brass. It is like gold plating without having to be paranoid about damaging literal gold.
