WCC 54 .45 Ammo

I just scored a 600 rd sealed tin of WCC 54 stamped .45 ammo. It is brass cased and does not attract a magnet but was wondering if it was corrosive or not? I also got 200 rds of steel cased EC 43 stamped .45 and im pretty sure this stuff is corrosive. Any know if the WCC is corrosive?

I was given some Korean War Vintage 30-06 Ammo. When I asked the guy if it was corrosive, he said WW2 stuff was. By the middle of the Korean War 52 on, he said the rifle stuff was not. This is FWIW.
