Спорт
In this video, we review steel vs aluminum SCUBA tanks. By the end of this video you'll have all the information you need to help choose the right Factors such as tank capacity, working pressure, size, weight, and buoyancy are all delved into. Some of the pro's of steel tanks are that they hold more gas than aluminum tanks of the same size, they tend to have a longer lifespan compared to aluminum tanks, and they also have better buoyancy characteristics. As for Con's: Steel tanks require more maintenance and are pricier than aluminum tanks.

Aluminum SCUBA tanks are lighter, do not rust but can oxidize, and are generally bigger due to thicker walls. However, they may have a shorter lifespan and are more buoyant, requiring more weight on the diver's belt.
The choice between aluminum and steel SCUBA tanks depends on various factors such as the type of dive, the diver's physical characteristics, breathing rate, depth, and price. Which tank do you prefer and why?

Do you prefer Aluminum or steel tanks? Let us know below!
Awesome review on scuba cylinders thanks Jose😊
Good review just giving people the information to make their own choices. Aluminum tanks do last a long time, just have to watch for the bad alloy years and manufacturers. It’s mostly ignorance in the diving industry saying old (outside the bad alloy) are not still good. For cold water I prefer steel to remove weight. Donate for a Dream
Aluminum tanks are more heavy than comparable steel on land but lighter in the water when empty. So you need more lead with aluminum that you have to carry in addition to the heavier aluminum tanks. Except for stage tanks where aluminum is mandatory i can not think of any situation where aluminum is the prefferable choice. The medium 12 liter steel at 232 bar at around 13 kg empty is a real nice setup with more air to breathe and less weight to carry than your 80 cft aluminium. It has much less impact on the trim.
im going to choose 12Liter Steel cylinders with max 200 bar, they are lighter than the 230 bar cylinders and nearly balanced when they are empty. On land less heavy than aluminum cylinders and under water also good to handle if it comes to sidemount. Will use them in fresh water with a drysuit.
Curious that you said steel tanks are heavier. I'm interested to hear what this is based on, because apples-to-apples capacity-wise, steel is lighter out of the water. The link in your video doesn't work and I couldn't find anything on your website about different tanks, so here's some info from Faber and Thunderbird: Al80 - 31.9 lbs LP85 - 31.2 lbs HP80 - 28.3 lbs
It continues to amaze me how pervasive the "steel tanks are heavier than equivalent aluminum tanks" myth is.
