- dsfyu404ed 11y agoA part made from cast aluminum will have a significantly higher environmental cost than the same part made from cast steel because pulling aluminum out of the ground is much more expensive environmentally, and monetarily (fuel/electricity aren't free) than getting the equivalent amount of iron out of the ground. Even if you make the parts from melted down anvils and beer cans that initial cost is still there (there's also a lot less aluminum around to be recycled than there is iron and steel). Materials and methods of processing matter a great deal. OEs care very much about this but the progressive fuel economy requirements make it worth their while meet the requirements all else be damned
