1 High Purity Your return on investment

2 Hydro our company High Purity worldwide Hydro is a Fortune 500 energy and aluminium supplier founded in 1905, with 36,000 employees in nearly 40 countries. We are a leading offshore producer of oil and gas, the world s third-largest integrated aluminium supplier and a pioneer in renewable energy and energy-efficient solutions. As we look forward to our next 100 years, we celebrate a century of creating value by strengthening the viability of the customers and communities we serve. The global need and consumption of high purity aluminium is steadily increasing. Whether for electrolytic capacitor foils, the semiconductor industry, decorative uses or for electronic storage systems, high purity aluminium is a necessity in all high-tech products. In order to meet the demanding requirements of our customers all over the world, Hydro set up the High Purity Business unit with manufacturing plants in Naoetsu (Japan), Vigeland (Norway) and Grevenbroich (Germany). All three plants excel in competence resulting in reliability and defined quality needed to meet the extremely high demands of our customers. Our employees are highly qualified and have collected the necessary experience and knowhow in metallurgy and manufacturing technology (metal purification & casting) as well as in trace analysis. Our customers also profit from our flat organisational structure. There is only one management team defining sales and marketing strategies and all manufacturing units use the same technical standards. However, you as customer can take full advantage of our commercial and technical customer support via our local sales offices. As the global leader in high purity aluminium, all our activities have one common target: to create the highest quality standards in close cooperation with our customers and to offer them made-to-measure solutions to their individual requirements.

3 Our plants in Japan, Norway and Germany are in the position to cover the complete range of production processes: 4N+ 3-layer electrolysis 4N and 5N segregation 4N and 5N continuous casting (slabs and billets) 4N and 5N static casting Slab and billet cutting to defined lengths Slab homogenisation top quality Production oduct on There are relatively few companies in the world which have the competence and know-how to manufacture high purity aluminium. The extreme purity of the metal can only be reached using complex refining technologies. It is not only necessary to remove or reduce the concentration of impurities such as silicon, copper and iron just to mention a few but also to reduce the alpha emitter such as uranium and thorium to a predetermined level. But, depending on customer requirements, we also have the ability to alloy elements even in the ppm range according to customers requirements. We use the 3-layer electrolysis as well as segregation (fractional crystallization) technology to refine aluminium. Only by combining these two technologies can we fulfil the requirements of the customers and reach the desired characteristics of the high purity aluminium.

4 Our basis material Raffinal is produced in our 3-layer electrolysis process. The purity of this aluminium is measured in parts per million (ppm) and ranges from to per cent. Raffinal is also used as a semi-finished product for further refining processes. innovative Products oducts The high quality standards of the electronics industry are reflected in the demands of the capacitor foil, hard disc and bright trim industries. We meet these requirements by supplying high purity aluminium produced exactly according to requested specifications. Raffinal Raffinal can be delivered in different product shapes sheet ingots, billets, ingots and pigs. Our products are made-to-measure depending on customer requirements and technical parameters so that they can be integrated into the customer s production process without any problems. We are continually improving the production chain in close cooperation with our customers. This results in even more efficient products as well as ideas that flow into the development of new products and gives you the opportunity to open up new markets. This is how we increase your return on investment.

5 This super purity 5N and 6N aluminium is commonly used in the semiconductor industries as a sputtering and thin film application. Kryal is an essential raw material in the microprocessor, memory chip production and as high purity aluminium coating for the metallization in the Flat Panel Display or LCD manufacturing process. This state of the art product is also found in the production of base plates for magnetic discs. Kryal is sold unalloyed in the form of pigs, sheet ingots & small ingots and also alloyed as extrusion billets, bars, rods, strips, sheets or plates in tailor-made batches. Kryal is produced in very close cooperation with our customers. All products are tailor-made according to the special applications and are always of a constant high quality meeting the standards of the demanding semiconductor industry. This generates long-term customer relationships and alliances and is proof of the satisfaction of the consumer. challenging Products oducts For applications which demand the absolute highest purity, we can offer you our Kryal products. This super purity aluminium is characterised in parts per billion (ppb) of remaining elements. Imagine, on a time scale, 1ppb would mean determining 1 single second within 31 years. K ya Kryal

6 Our integrated management system comprises of quality management according to ISO 9001, environmental management ISO 14001, a HSE (Health, Safety and Environment) system as well as a proposal and idea management. Our laboratories are equipped with state of the art apparatus and all the necessary instruments to ensure the high quality Management highest level of competence across the complete production process. These include Glow Discharge Mass Spectrometers (GDMS) which can detect trace impurities in the parts per billion range, Optical Emission Spectrometers (OES), Atomic Absorption Spectrometers (AAS), Hydrogen Analysers (HMAT) as well as equipment to measure the hydrogen content in the liquid aluminium during casting (ALSCAN). Our activities in process capability guarantee a constant and reproducible quality and innovative ideas for innovative products. However, our performance does not come from certificates. It comes from competent highly qualified employees who are prepared to commit themselves to creating high quality products. The high safety standards continue even after production is completed. Exact inspections and controls ensure that the products are packed and transported with the utmost of care so that they reach our customers without any incidents and completely unscathed. Feel free to contact us so that we can offer you high quality products for your needs. Our staff are at your disposal at all times.
