He added that there is a strong sentiment in the markets for aluminium casthouse products.

"Hydro also supplies casthouse products based on scrap and remelting of ingot, and the availability of scrap and remelt ingot remains under pressure," he said.

Ebbesberg said that important alloying elements have experienced price hikes relative to aluminium.

"This needs to be reflected in Hydro's pricing of aluminium casthouse products going forward," Ebbesberg told a customer meeting in Essen.

He said that the underlying sentiment in the market for alloyed casthouse products remained solid.

Hydro is presenting an array of aluminium products and solutions at the prestigious Aluminium 2010 trade fair in Essen, Germany, on September 14-16, where about 18,000 visitors from more than 100 nations are expected to attend, making it one of the most important meeting place for the entire aluminium industry.
