Aluminium foil is also increasingly important in automotive components such as impact energy absorption structures and in catalytic converters. Favoured over steel because of better corrosion resistance and weight economy, special aluminium alloys provide the physical properties required in these aluminium foil applications.
Because aluminum is lighter, it allows automakers to increase dent resistance—they can make body panels thicker while still lowering weight. And a lower weight vehicle has better acceleration, better braking and better handling. In addition, lighter vehicles can haul and tow more because the engine isn’t carrying unneeded weight.
*Continuous growth in automotive use
Use of automotive aluminum has grown continuously for 40 years. Aluminum is now second only to steel as the most used material in vehicles.
*Recycled at record levels
At the end of a vehicle’s life, nearly 90 percent of the aluminum, on average, is recycled.
Compared with a fleet of traditional steel vehicles, aluminum use saves the equivalent of 108 million barrels of crude oil in energy.
Pound for pound, aluminum can absorb twice the crash energy of mild steel. Larger crush zones can be designed without corresponding weight penalties.
Our company HTMM, has ten years experiences on aluminium foil and supply a lot kind of foil. Good reputation and high quality is worthy to have a try.
