Primary Aluminum

Primary aluminum we commercialize for customers requiring high-purity material with low iron content and minimal trace elements.

Master Alloys (Distributed)

Grain refiners and modifiers we commercialize and distribute for the foundry industry. We do NOT manufacture these master alloys: achieving a homogeneous dispersion of TiB₂ or strontium at production scale is highly specialized. We supply them in rod or waffle form from specialized producers, ready for in-furnace addition.

Deoxidation Aluminum

Aluminum in donut and piece form for deoxidation and degassing processes in the steel industry.

Extrusion Alloys

Bars and ingots with optimized composition for the aluminum profile extrusion industry.
