AMS ®

AMS® is a patented Lydech product which employs between three and five thin, parallel and low emissivity metallic layers to markedly cut the contribution of infrared radiation heat flux in high temperature applications. The metallic layers, commonly foils of aluminum or stainless steel, are separated by an expanded metal mesh to reduce interlayer contact and augment the thermal resistance of the composite.

Materials – Metallic Layer

Aluminum – Foil Layers and Carrier

• 0.02 to 2.5 mm

• Flat or Embossed

• 1000, 3000 and 5000 Series Alloys

• Lightweight

• Excellent formability

• Operating temperature < 300 °C

Aluminized Steel – Carrier Layer

• Used as a support for Aluminum Foil Layers

• 0.25 to 1.0 mm

• Flat or Embossed

• Various coating weights and draw quality steels

• High strength materials

• Operating Temperature < 500 °C

Stainless Steel - Foil Layers and Carrier

• 0.1 to 2.5 mm

• Flat or Embossed

• Ferritic and Austenitic grades selected as a function of operating temperature and corrosion requirements

• High strength and high temperature applications

• Operating Temperature < 1000 °C

Thermal Performance

• Excellent performance in thermal environments heavily dominated by IR radiation

• High lateral thermal conductivity to spread heat away from hot zones

Acoustical Performance

• The thin foil layers and alternating air gaps provide marked noise absorption

• The use of pierced or perforated layers can further contribute to the noise reduction capacity of the composite

• High transmission loss for better acoustic isolation

Mechanical Performance

• Hemmed edges for handling safety and increased product robustness

• Roll and plate embossment provides an increase in part rigidity

Environmental Performance

• Fully recyclable

• Raw material is comprised of 80% recycled material

• All alloys resist exposure to common automotive fluids

• All alloys resist long-term exposure to corrosive environments
