Is Brass FCC or BCC at room temp?

[Jellopool]

Experts:

Is brass FCC or BCC at room temperature? Also, I was wondering if it was Austenite or Martensite? Specifically, the brass used in brass bearing races. Thank you.

Ha, like it's that simple! Which brass alloy? Below 35% Zn it's FCC, above it's BCC. Neither is austenite or martensite.
