Are they aluminum or steels?
They are steel. I thought about getting a an extra set for my inspo and then I did the math and decided that DR Express had a better deal if you need valves as well. $300 plus shipping from NE Scuba Supply for 1 year old tanks, no valve (and obviously not o2 clean) and no vip - DR Express will ship you a pair of new O2 clean ones with valves, VIPs, o2 and dil stickers for $558 shipping included.
