does more conductor resistance mean the aluminium is not in the purest form
whats your question by the way ? the chassis is goodnot very familiar with your choice of engine.
There has to be a question to have an answer
First, let me tell you on an atomic scale where electrical resistance comes fromEvery metal piece is a huge mash-up of metallic regions or crystalsThere are separations between those regions, with which electrons collideElectrons are free to move about in the metallic regions, but require extra energy or force to move from one region to anotherImpurities mean more separation between metallic regions and therefore more roadblocksSo does cold-working the metal, which can shear the metallic regionsThe best conducting samples are ones that have larger metallic regions, like pure metal crystal formed at high temperatures and cooled very slowlyUnfortunately, those are not very practical because they're not particularly flexible, not to mention the difficulty in trying to grow the crystal structure, so chances are you won't see them unless you work in a physics lab studying conductive properties.
