That depends on the brass, the particular gun its fired in, how high the pressure is of the cartridges its used for, the method used for resizing, the design of the brass and probably some things I've forgotten.
I've had some brass that only went 3 or 4 reloadings before it had to be discarded. In other circumstances, the number of times brass can be reloaded is over 20. The wide variability means you have to know how to evaluate brass to be sure its reloadable. The mouths should not be cracked and the primer pockets should not be loose. You should also run a wire down the inside of the case to make sure a head separation isn't starting.
All that said, the first thing to fail on straight walled cases fired in relatively low pressure cartridges will be the mouth of the case which will start to crack.
