Replacing cast iron and traditional steel components with lightweight materials such as high-strength steel, magnesium (Mg) alloys, aluminum (Al) alloys, carbon fiber, and polymer composites can directly reduce the weight of a vehicle's body and chassis by up to 50 percent and. Replacing cast iron and traditional steel components with lightweight materials such as high-strength steel, magnesium (Mg) alloys, aluminum (Al) alloys, carbon fiber, and polymer composites can directly reduce the weight of a vehicle's body and chassis by up to 50 percent and. The 19 inch chassis (482. 6 mm width) ensures global compatibility across industries. Steel chassis offer maximum strength and EMC shielding, ideal for industrial environments. Surface finishes like powder coating. Energy Transition and Sustainable Development in Algeria: The Challenges of Green Economy, Finance and Business Economics Review, Vol. 65 – a 20 percent improvement compared to more traditional tractor styling. Other advances such as trailer aerodynamics, tire and engine improvements, use of alternative fuels and electric. As potential alternatives to traditional engineering materials, lightweight materials intended for vehicular applications can be broadly classified into four principal categories: light alloys, exemplified by aluminum, magnesium, and titanium alloys; the high-strength steel (HSS) group.
