Is aluminum alloy expensive or high carbon steel expensive?
Aluminum alloy of course, a little longer, and will be much lighter.Generally, aluminum alloy frames are much more expensive than those of high carbon steel.
Aluminum must be expensive, carbon steel is rubbish
Aluminum alloy more expensive than carbon steel, because the material is not the same, the processing is not the same!
Here is a concept to be worked out:High carbon steel is more carbon in iron. The strength is better than general iron.Aluminum alloy is not pure aluminum, if it is pure aluminum frame, it can not be used as frame, aluminum alloy frame generally after T6 (T4), the intensity is absolutely guaranteed.Now the material is generally so divided:The iron - Aluminum Alloy frame - magnesium alloy - titanium alloy, carbon fiberThe top is divided into grades.
