Bonding Gold and Titanium into an alloy takes more than science, it takes a large bank account. One as big as Tony Stark’s ego. Gold by itself is quite malleable, but too soft for adequate armor. And if you’re going into battle with just a flying suit of armor, you’re going to need something a little tougher than that. Combine it with titanium and you’ve got what you need to make a strong, aerodynamic and powerful suit. And it is just plain pretty, like these socks.
