Impact Extrusion

To produce industrial aluminum of this caliber, Novelis begins by carefully controlling the composition of the alloy, then taking exceptional care in the casting procedure to avoid non-metallic impurities. The surfaces of the aluminum ingots are then sawed and scalped to remove any new impurities before rolling. These ingots are preheated for long periods for optimal homogenization of the metal structure, then hot- and cold-rolling procedures achieve high surface quality. “Bright rolling” delivers the highest possible surface consistency and reflectivity. The result is an aluminum surface reflective enough to be used as a mirror.

The key to successful power generation through wind is efficiency, and industrial aluminum is playing a key role in making wind turbines lighter. Working together with our partners, we’ve created a smaller, lighter tower casing behind the rotor blades, as well as an innovative aluminum enclosure for the turbine’s generator that is lighter and more efficient than fiberglass composite housings used previously. This housing reduces fire risk thanks to aluminum’s incombustibility and helps cool the generator due to aluminum’s thermal conductivity, extending the aluminum enclosure’s functional life. It also maximizes the unit’s recyclability and protects the generator from lightning, since the aluminum acts as a Faraday cage and is non-combustible in the event of a lightning strike.

Photovoltaic (PV) Solar Power converts light from the sun directly into electricity via the photoelectric effect. Aluminum makes an ideal substrate material to support the thin film of photovoltaic solar cells, as well as a safe, attractive housing for the absorber. Its lightweight nature makes the units easy to move, and its resistance to corrosion extends the lifespan of the units. Sheet-rolled, bonded industrial aluminum can also make an effective support for PV units.

The versatility and benefits of aluminum parts for home appliances are now a common feature of kitchens – ovens, refrigerators, dishwashers, coffee makers, pots and pans – adding elegance to everyday life at a lower price point. Industrial aluminum used in household appliances is easy to clean, thermally conductive and resistant to dents, marks, scratches and corrosion. Aluminum is especially suited for the design and construction of refrigeration systems. Aluminum refrigeration transmits heat rapidly, facilitating the cooling process and guaranteeing highly efficient operation. Some of the biggest names in refrigeration worldwide use Novelis’ aluminum products in painted, brushed, plain or embossed form.
