Aluminum Zinc Magnesium resistivity off by factor of 10

Someone else please sanity check me:  I have been looking into technical properties of alloys, and it looks like Aluminum Zinc Magnesium represents some alloy within the 7000 Aluminum series.  But the resistivity properties I find for those are on the range of 4.3e-8 Ω.m, not 4.3e-7 Ω.m as is on the game files.  That should make it a much better material for railguns (though still not zirconium copper).
