Although you didn't have it bolded, I noticed the phrase
"even with a band of iron and brass"
(doesn't say aluminum, titanium, and copper, but close enough for government work.)
Thanks again.
Note the word translated as brass:
05174 n@chash (Aramaic) {nekh-awsh'}
corresponding to 05154; TWOT - 2858; n m
AV - brass 9; 9
1) copper, bronze

Thank you.
