This is a cool question and made me think.

Common metals for safety razors (not including plated razors) are:

1. Aluminum
2. Stainless steel
3. Titanium
4. Brass
5. Bronze

The prices of these razors depend mainly on how difficult it is to machine. Titanium, I believe, is the most difficult to machine. The material cost also varies, but most of the price is reflected in how much time it takes to machine a razor.

From a marketing perspective, people solid metal razors for one of a few reasons.

1. Appearance
2. Weight preference
3. Some people like a patina

To compete with the other metals, Aluminum Bronze only appeal to people who want a dark metal razor, but no patina. Most people who buy Brass or Bronze want a patina.

That being said, as someone who owns a stainless steel razor and a titanium razor, I’d totally buy an Aluminum Bronze razor knowing it won’t get a patina (or at least not much of one). The only question is price. How difficult is it to machine? I assume it’s pretty easy.
