Aluminum builds a better vehicle. Aluminum's use in autos and commercial vehicles is accelerating because it offers the fastest, safest, most environmentally friendly and cost-effective way to increase performance, boost fuel economy and reduce emissions while maintaining or improving safety and durability.
Steel and aluminum is continually fluctuating based on global supply and demand, fuel costs and the price and availability of iron and bauxite ore; however steel is generally cheaper (per pound) than aluminum.
Competitive materials, such as aluminium, are at a significant cost disadvantage over steel for all aspects of the car body structure manufacturing process.
STEEL vs ALUMINIUM
In raw material costs,Aluminium is 3 times more expensive than steel.
In conversion cost,aluminium is 2 times more expensive than steel.
In assembly,aluminium is 20 to 30 % more expensive than steel.
In total,an aluminium structure is estimated at 60 to 80 % more expensive than a conventional steel design.
