What is QuietSteel® ?
QuietSteel® is a suite of engineered
multi- layer composites with various engineered viscoelastic
cores sandwiched between two layers of steel.
This viscoelastic core is a "tuneable" formulation,
allowing vehicle designers to attenuate specific frequencies
depending on where in the vehicle they use QuietSteel®.
The steel laminate may be further engineered
with corrosion resistance or other value- added processing.
When this initial processing is complete, customers may form,
stamp, and weld QuietSteel® as they would any standard
steel.
And unlike steel treated with other damping material, 100%
of QuietSteel® can be easily recycled.

The QuietSteel® Car.
More and more manufacturers are discovering
that QuietSteel® applications are virtually limitless. The fact is, QuietSteel® is a superior alternative practically
anywhere ordinary steel is utilized.
When the Alliance team designs QuietSteel® into an engineered
system, preliminary studies suggest a typical total system
weight and cost reduction up to 20% – while achieving
noise reduction levels up to 50%. The result? Enhanced fuel
efficiency, reduced assembly time, total recyclability and
dramatically improved quality.
