I was reading the other day some posts that would have one believe stainless steel mods weigh 3 to 3.5 times as much as aluminum mods. Could this be true?!
While it is true that stainless by volume weighs 3 times as much as aluminum, when used in mods, the mod often comes no where near 3, 2 or even 1.5 times as heavy!
Why is this so?
First: Stainless steel has far greater tensile and hardness ratings when compared to aluminum, which not only gives stainless steel its great scratch resistance, but also allows us to run a much thinner mod wall diameter then aluminum without sacrificing strength, thus saving some weight, as well as a giving us a thinner mod to boot!
Second: Many mods utilize brass, steel or stainless steel endcaps, buttons, center posts, atomizer threads/adapters and parts, which are all much heavier then aluminum. Brass, Stainless and Steel also all have near equal weights by volume.
No doubt a stainless steel mod does weigh more then aluminum, but the increased strength in the atomizer thread area and cap to body thread areas (the most likely areas to strip or wear out) as well as it's corrosion resitance and scratch resistance, makes Stainless steel a pretty attractive option in the use of mods! Stainless steel's heft is quality you can feel.
