36. Aluminium is the metal of the future
• Lightweight • Formability
• One-third the density of steel • Extrusion, rolling, casting
• Low melting point vs. steel
• Recyclability
• 5% of original energy consumption • Excellent conductivity
• 75% of all aluminium produced still in use • Thermal – electrical
• Corrosion resistant • Alloying technology
• Gives a wide range of physical properties
• Oxide layer
Properties lead • Aluminium-intensive urbanization and infrastructure
to increased • Climate challenge – aluminium as part of the solution
market share • Recyclability more important with high energy prices

38. Innovation drives aluminium demand
The new trend: “Aluminium cars”
New Audi A6 contains a large amount of aluminium and aluminium
solutions – making it lighter, safer and more environmentally sustainable
EU: Stricter emissions limits
Aluminium: Part of the solution
Hydro has developed new multilayer sheet materials which enable car
makers to greatly reduce nitrogen oxide emissions from vehicles
Aluminium tubing for solar collectors
Hydro is taking the lead in Europe in the introduction of aluminium tubes
to the solar thermal industry, replacing traditional copper tubes
