I am looking for info on grades of aluminum like 3003, 5053, 6160 what's the differance witch one are cheaper and weld easy please explain
Aluminum rims are a whole lot better on the mechanical stand point, they are lighter, usually stronger (depending on the alloy) and they allow for better heat disapation. Lighter rims will save gas money (nothing you will notice, maybe an extra mile/tank, if that). Depending on the alloy used in the aluminum rims, they are usually stronger and can take more froce abuse, just as long as they don't get scuffed up, ect. With the better heat disapation. When the brakes heat up, the heat is sent out ever direction, mostly through metal. Aluminum (alloy) is a great conductor of heat.
