What’s better steel or aluminum scuba tanks?

Because steel is stronger and more ductile than aluminum, construction of a tank requires less steel than aluminum. This usually means that for an equal gas capacity, a steel tank will have a total weight less than an aluminum tank yet have better buoyancy characteristics.
