Does sweat oxidize aluminum handlebars?(8 posts)

Does sweat oxidize aluminum handlebars?DT

I read somewhere recently that sweat will eventually oxidize your handlebars if they're aluminum. I ride without gloves, and I live in Mississippi, so I sweat a lot on my handlebars. Is this somehting I should be concerned about? If so, are carbon bars a good alternative? Thanks!

I sweat a lot and my stem, spacers and cable holders are full of salt. I woudn't worry about sweat and aluminium since it very commonly used in ships, diving equipment, etc.

That really depends on the flavor of aluminum. 6061 is very corrosion resistant, but still somewhat suseptiable to salt corrosion. 7075 corrodes very easily in salt water, it has zinc added to it to make it hard and any boat (one used in salt water) owner can tell you zinc is used as a sacrifical anode. I would check under handelbar tape for problems if any.

Uh - while it is true that zinc is used as a sacrificial anode material, that is not why 7075 is more susceptible to corrosion - it has more to do with the underlying microstructure of the material (i.e., strengthening precipitates) - 6061 is a more homogeneous material in that sense, and doesn't have the same nuclei for localized attack that ppt hardened alloys like 7075 or 2024 do.

Un wrap your bars and see how much salt has accumulated. Obviously you want to wipe off the salt, and then see if there is corrosion. This will give you a guide as to how often to wash and re-wrap your bars. That said, I've seen bars with lots of oxide and no failures, so unless things get outrageous, you don't need to lie awake nights.
