There are lots of ways to look at it. One as mentioned that most of it went on cap ships like Midway class and Manowars. The tungsten shortage would be more felt in border worlds where I understand "Arena" takes place. And locals have to use what they have and improvise.
As to OP original question most likely the ships made in core worlds would be bit more advanced.
