AlCa10 improve the as-cast surface quality of 5000 series alloys among other several applications.

Aleastur AlCa10

AlB5 increase the purity and electrical conductivity of aluminum by reacting with chromium, titanium, vanadium and zirconium and making them precipitate as insoluble borides.

Aleastur AlB5

AlB6 increase the purity and electrical conductivity of aluminum by reacting with chromium, titanium, vanadium and zirconium and making them precipitate as insoluble borides.

Aleastur AlB6

Deoxal 20P reduce oxygen activity in slags with variable Al metallic content and packing. New applications and steel grades require lower sulfur content, so slags need to be more active in the desulphurization process. It means to have as low as possible oxygen activity. Carried slags form EAF and BOF during tapping process lead to more oxidized slags that expected.
