Eight filtration tests have been done at Hydro Aluminium’s reference centre at Sunndal. Two different grades of CFF (Ceramic Foam Filter) and two different grits of BPF (Bonded Particle Filter) from Pyrotek were tested. The alloy composition was the same for each test. The inclusion content in the m...

In an industrial furnace, fired with a hydrocarbon-based fuel, the furnace atmosphere will essentially consist of a mixture of the four species: CO₂, H₂O, O₂ and N2, all of which thermodynamically will react with aluminium. Earlier publications have addressed the question of the thermodynamic versus...

Oxidation is of great interest in the casthouse, as oxidation equates to metal loss. Therefore, a method to study the oxidation in a casthouse was developed and tested on AlMg alloys and AlMg alloys with beryllium additions under a variety of atmospheres created by an airfuel or oxyfuel burners.
