Aluminum Scuba Tanks

When choosing between steel and aluminum scuba tanks, it’s important to consider dry weight and size, as these can affect your buoyancy and overall comfort.
In scuba diving, dry weight refers to how much a tank weighs on land—and it’s something you’re going to want to consider if you plan on lugging your tank around when you’re not in water. Steel is stronger and more durable than aluminum, which is why tanks made with the latter usually have thicker walls to compensate for the reduced tensile strength.
