Novelis anodising qualities for innovative facades

Aluminium -construction material with a future Aluminium is the ideal material for innovative and demanding facade designs. Quality, cost-effectiveness, exceptional protection and strength are all key reasons for using aluminium in construction projects. This light metal is also easy to work and features a brilliant metallic appearance - two features that make it ideal for a whole range of customised and modern design possibilities in facade cladding. It is also durable and has excellent green credentials since it can be recycled with ease. Novelis is the leading supplier of aluminium...

Anodised aluminium is the perfect material for high quality facades, roofs and interior cladding where attractive and innovative designs are needed. The special surface combines decorative brilliance in terms of colour and material with excellent durability in the face of extreme loading and weathering. One of the greatest architectural challenges is to design large-dimensional structures: Anodised aluminium can be used for a whole range of applications and is also suitable for the facades of public buildings over 20 m tall. High-quality anodised aluminium for permanent surfaces is the...

Aluminium in anodising quality for brilliant applications Novelis anodising quality is easy to work, thereby enabling customised facade designs and the use of various installation techniques. Flat sheet Cassette with bolt fastening Conventional fastening techniques for curtain-type, ventilated facades are possible, as well as modern bonding techniques for invisible fastening or stud welding. 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...

Quality and colour with anodised aluminium Anodising is a process through which a defined aluminium oxide layer is generated by immersing the aluminium in an electrolyte in the presence of an electric current. The special features of anodising quality (AQ) Fine grained, homogeneous structure Dyeing is also possible. The most popular method of anodising aluminium is the direct current (D.C.) sulphuric acid process. The initially colourless anodised surfaces are then coloured, if needed, using either adsorptive (immersion) or electrolytic dyeing processes. High quality through increased...

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. 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. For quality architectural applications Aluminium J57S® for batch anodising Aluminium...

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.

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 brilliant 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...

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. » 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 annealing Checks on the end product • Dimensions and flatness to DIN EN...
