The chain and gears, and the spokes on the wheels are still susceptible, though.
Aluminum corrodes quickly in salty environments, if you live near the beach you figure this out soon enough. Carbon fiber does not corrode, but exposure to UV light and some chemicals can cause the epoxy used to bond the carbon materials to break down. Titanium is impervious to corrosion, UV light, and chemicals. Steel is more durable than aluminum or carbon fiber, cheaper, and can last decades in bad environments so long as you keep it clean.

I've had a couple steel road bikes which were made in the 1940's, and they are still in good condition now.
