Automotive Heat Exchangers
Novelis is a leading supplier of light gauge, narrow-slit aluminum fin stock (bare and clad) and brazing sheet used in the production of heat exchangers. Our products are the material of choice for Original Equipment Manufacturers (OEM) and aftermarket component manufacturers in the auto industry. Aluminum’s high thermal conductivity, low density, corrosion resistance and durability make it a perfect match for today’s demanding automotive heat exchanger requirements. In fact, most heat exchangers used in new vehicles today for climate control, engine cooling and auxiliary cooling are made from aluminum.
Novelis materials are highly engineered products with superior gauge control capabilities, precise width tolerances and exacting chemical and physical properties. Each of these critical variables is met with industry-leading technology and product development support. High-Strength/Sag Resistant (HS/SR) automotive fin stock and Novelis Fusion™ brazing sheet are prime examples of our technological leadership.
The backbone of our brazing sheet product family is the patented X900 family of long-life, corrosion-resistant core alloys. These materials are produced with a range of strengths to suit many applications and brazing processes. A variety of braze liner alloys are available and designed to have excellent fluidity in a wide range of braze furnaces. Tube stock material can be supplied with our High-Strength Corrosion/Erosion-Resistant X397 water-side liner alloy.

Flexible Tubes
Aluminum has proven to be an effective material for specialized tubing and insulation within vehicles of all kinds. Novelis leads the way in developing new alloys, coatings, treatments and combinations with other materials (such as paper and fiberglass) that make our aluminum products flexible yet effective barriers for a wide range of purposes.
OHLER® Flexible Tubes
Novelis is one of the leading suppliers of flexible tubes and hoses for the automotive sector with products used as:
- Heat protection
- Air ducts
- Exhaust pipes
- Thermal insulation
- Energy absorption
Heat Protection Tubes
Our OHLER® product line is specifically designed for use in automobiles and caravans.
- Heat Protection Tubes are made by layering several kinds of aluminum alloy foil and other materials such as fiberglass and plastic with corrugations. The excellent reflectivity of the aluminum alloy on the external surface reflects radiant heat, and its insulating power additionally serves to protect the tube’s content from heat sources. These products have great flexibility but high dimensional stability, and can be compressed or extended as required. They can also be fastened or mounted easily by crimping the end fittings.
Heat Protection Sleeves and Mats
- Heat Protection Sleeves and Mats extend our expertise in protective tubes to other shapes and uses. Layers of aluminum foil are combined with fiberglass for products that can withstand temperatures up to 750 degrees Celsius.
Flexible Tubes for Hot & Cold Air Distribution
Air Flow Routing tubes are designed to channel different kinds of air to appropriate destinations. If you have a specialized vehicle and need superior flexibility in your air duct tubing, these products lead the industry.
- CARADUCT® tubes are multi-layer, grooved, flexible tubes that are wound from a combination of aluminum and paper layers. They possess a particularly high crushing strength and very good insulation properties. Through high flexibility and small bending radii, they offer the user the ability for a good space usage, particularly when laying out in corners.
- Dükerrohr is a twin tube distinguished by a particularly high insulation effectiveness to reduce temperature drops in the warm air ducting. Because it is installed outside of the vehicle, it carries additional protection against water and oil splashes.
Exhaust Pipes
- CORMIFLEX® tubes are folded spiral-seam pipes made of high-grade steel precision strip. Because of their high temperature resistance, they are predominantly used for exhaust gas routing in passenger car, utility vehicle, RV and marine heating units. Their temperature resistance reaches up to 350°C. CORMIFLEX® PLUS bears additional resistance against corrosion due to salt and other aggressive agents.
Thermal Insulation
- High-Temperature Insulating Hose (HT hose) protects heat-conveying lines and prevents thermal damage to adjoining parts with a fiberglass and double-coated silicon rubber top layer. The HT hose is available as a self-contained or re-closable sleeve or as custom-made mat. The approximate surface temperature of the duct can be up to 500°C.
Energy Absorption
- Energy absorption elements are an aluminum-paper composite element manufactured to protect passengers during impact. They conform to requirements of the US standard for head impact in the upper passenger compartment (FMVSS 201) as well as side impact (FMVSS 214), and maintain their force-deformation path characteristics at a temperature range from -40°C up to +110°C. The top layer made of paper serves as prevention against rattling. They are currently used in roof lining, main frame, pillar trim, knee bolster, door panel, bumper beam and bumper cover panel.
- Extruded energy absorber (OEEA-Element) is a further development of our EA-Elements and fulfills sophisticated requirements of the European Community (EU) concerning lower-leg impact prevention. It is ideally mounted between the spoiler and cross beam of the vehicle.

License Plates
Light, durable and corrosion-resistant, pre-painted aluminum sheeting products from Novelis make an ideal base for car license plate manufacturing. The alloy and coating are specifically adapted for government requirements and delivered in accordance with local regulations. Benefits include:
- Excellent adhesion qualities for reflective film and other applications thanks to a clean, grease-free surface. Choices include top-coating or pretreatment options, or double-coated for non-reflective plates.
- Easy processing and corrosion resistance is ensured by a specialized coating on the reverse side.
- Versatile delivery options range from coils and sheets to cut blanks and ready-made license plates, delivered with rounded corners, embossed edges and painted finish.
- Minimum burr on edges thanks to superior processing.
- Consistent quality is ensured by excellent quality controls—and compliance with all regulatory bodies, including EN, DIN, ASTM, BS and ECCA.
