Brighter ideas with aluminium NOVELIS Anodising qualities and continuous-anodised aluminium for innovative facades

Aluminium - construction material with a future ■ Easy to work; numerous design possibilities ■ Brilliant surfaces through cutting-edge processing techniques ■ High weathering and corrosion resistance ■ Excellent electrical conductivity ■ High thermal conductivity ■ Environmentally sustainable, highly recyclable THE MOST POPULAR APPLICATIONS ■ Anodised and coated facades ■ Roof and wall systems ■ Bridge and support structures Aluminium is the ideal material for innovative and demand- Quality, cost-effectiveness, exceptional protection and strength are all key reasons for using aluminium in...

Anodised surfaces for demanding architecture Anodised aluminium is the perfect material for high quality facades, roofs and interior cladding where attractive and innovative designs are needed. The special THE KEY PROPERTIES OF ANODISED ALUMINIUM surface combines decorative brilliance in terms of colour Decorative, with permanent metallic gloss and material with excellent durability in the face of extreme loading and weathering. Large range of colours Corrosion resistant (in neutral ph range) and weather resistant Firm bond with the metal surface, therefore no peeling, chipping or corrosion...

Aluminium in anodising quality for brillant applications Novelis anodising quality aluminium is easy to work, thereby enabling customised facade designs and the use of various installation techniques. Conventional fastening techniques for curtain-type, ventilated facades are possible, as well as modern bonding techniques for invisible fastening or stud welding. FLAT SHEET In addition to typical outdoor elements such as panels, cassettes or flat sheets, unusual facade types such as striking rhombus forms also meet the demands of modern architecture. CASSETTE WITH BOLT FASTENING CASSETTE WITH...

Quality and colour with anodised aluminium Anodising is a process through which a defined alumiin an electrolyte in the presence of an electric current. THE SPECIAL FEATURES OF ANODISING QUALITY (AQ) Dyeing is also possible. The most popular method of Fine grained, homogeneous structure anodising aluminium is the direct current (D.C.) sulphuric nium oxide layer is generated by immersing the aluminium acid process. High quality through increased manufacturing The initially colourless anodised surfaces are then process from production coloured, if needed, using either adsorptive (immersion)...

Colour solutions for decorative anodised surfaces A broad varity of UV-resistant colours ranging from a light bronze tone to black are available. Gold and other colourings are also possible. Intercity station, Frankfurt /Main Material: J57S, natural anodised Colours act as a crucial part in architecture and, in particular, for facades. Colour contrast areas and matching colours to the surrounding structures are key factors when developing construction projects. Novelis aluminium can be coloured using either the electrolytic process with metal salt or the immersion process. Minggugong...

Special anodising quality begins with a J In principle, all aluminium alloys can be anodised. For high-quality and attractive architectural applications, a special alloy grade is needed, which Novelis can supply under the product name "J57S". This product J57S can also be delivered ready anodised under the brand name J73A. High-quality anodised aluminium combined with comprehensive advice and service from Novelis provides the basis for successful projects that deliver outstanding results. FOR QUALITY ARCHITECTURAL APPLICATIONS Aluminium J57S for batch anodising Aluminium J73A is supplied...

Anodising qualities in astonishing brilliance Consistent alloy quality and optimum anodising processes The special anodising properties coupled with a diverse provide the anodising quality from Novelis with their range of possible treatments and applications deliver exceptional metallic gloss. the perfect conditions for applications, demanded by HOT AND COLD ROLLING (heat reatment/surface quality) CASTING TECHNOLOGY (fine homogenous grain structure) ALUMINIUM & ALLOYING ELEMENTS (chemicals and narrow tolerances) Qatar Science & Technology Park, Doha Year constructed: 2009 OPTIMUM ANODISING...

NOVELIS J57S Anodising quality used for architecture worldwide J57S has been used successfully worldwide in ambitious architectural projects over several decades. J57S offers a consistent high quality, independent of the time of purchase. Therefore, the high quality of J57S enables to reach colour- and gloss-uniformity after anodising, even if mixing the production lots. Particularly the brillant metallic appearance of the surface makes the difference, between commercial quality and the specific J57S alloy. Impressive references around the globe demonstrate the diversity of possible...

NOVELIS J57S Attractive anodising quality The J57S alloy has been specially developed to deliver brilliant surfaces in high quality. The very narrow tolerances of the chemical composition and manufacturing parameters are metallurgical key requirements, if the colour and gloss are to be uniform. After conducting any necessary further processing operations such as bending, punching, drilling etc., J57S can be used for batch anodising. Two factors influence the anodising result - the metal and the anodising process! High-quality anodising results are only possible if both processes are...

NOVELIS J57S The manufacturing processtight controlled production To ensure consistently high quality, J57S production operations are subject to strict quality checks covering the entire manufacturing process from initial casting right through leaving our plant. PRODUCTION CHECKS Ingot production Casting parameters, e.g. temperature control, speed and filtering Ingot pre-treatment, e.g. scalping, sawing Pre-heating and hot-rolling Pre-heating, homogenisation, temperature control and degree of rolling Cold rolling/intermediate annealing Degree of rolling, flatness and surface Intermediate...
