Steel to lead lightweighting efforts in transportation?


While carbon fiber and nanomaterials tend to gain all the hype, other advanced structural materials such as magnesium and advanced high-strength steel (AHSS) will have a greater impact on efficient energy usage in the transportation sector, according to a recent report by Lux Research (Boston, MA).

While AHSS remains the current leader in lightweighting according to Lux Research, carbon-fiber reinforced plastics (CFRPs) can offer greater benefits, while aluminum alloys occupy the middle ground. Magnesium is the lightest structural metal, though it is hobbled by concerns about availability, and titanium's cost continues to inhibit adoption outside of a few high-end applications, according to the report.
