Almost always steel. There are a few aluminum tanks out there, and 
aluminum scuba tanks. But commercial oxygen tanks are usually steel.
Oxygen cylinders are safe to use, assuming there is no pressure in 
them. A guy who used to work for me made a bunch of cool bells from 
some, plasma cutting a flame pattern at the bottom. And some 
metalshapers cut off the bottoms and use them for sinking dies for hand 
hammering sheet.
Do not use acetylene cylinders under any circumstances- they have all 
kinds of nasty stuff in them.
