Alcoa quality
Alcoa's billets are produced to provide the best performance at the extrusion press in terms of speeds, surface finish and mechanical properties. Before casting, the molten metal is treated to ensure it is clean and free of excessive hydrogen contamination. Alcoa extrusion ingot is virtually free of dross, porosities, metallic inclusions, oxides or other undesirable contamination and discontinuities. The chemical trace elements are controlled to a very low contamination level. The internal microstructure is modified through a controlled thermal treatment known as homogenizing process. The main objectives for homogenizing the billets are: minimize the detrimental effect of the â€as cast†Fe phases, eliminate grain or micro- segregation and break up the intermetallic constituents producing a well refined easier to extrude microstructure.
