Re: Aluminum Wire
Copper oxide conducts electricity, aluminum oxide does not, therefore if you come across house wireing and do not have the means to replace it be diligent to coat the AL wire with oxide inhibitor.
Also be aware aluminum wire will not take repeated flexing as well as copper.
As with welding alumnum the oxide doesn't conduct and therfore needs to be removed. If it is not cleaned if will generate heat across the AL oxide. That is also why rookie welder often blast thru before the heat is high enough to make a good weld.
Most house main input feeds into the load center are copper plated Al. In my house they are raw AL. Also most grounding rods (pounded into the ground) are also copper clad AL. It is basicly done to save cost.
I do not recommend using Al wire on FIRST robots.
Knowledge is power but ingnorance is false bliss.
I just wish I knew how to spell.
