Help to identify wire

[paul davis]

Hi all
I have a reel of mig wire which has X606 on it but I cannot identify what actual wire / composition it is. Can anyone shed light on this for me. cheers

What does it look like? Any other info on the label?

the wire is on a reel in a brass cage
wire is dark and only 4 layers on a 15Kg size spool/drum
no other markings
came from a job lot of either duratrode or xergon
many thanks for any help
