•    Description:  The 25th article in the series, this article covers part three of the press quenching effect on product quality. Applying and controlling the adequate quench rate is essential for achieving the structural soundness of the profile in terms of mechanical properties, overall profile dimensions, and tolerances. This can affect post-extrusion processes such as anodizing, resulting in an unacceptable surface finish. In part three, the article addresses low mechanical properties caused by billet post-homogenization cooling, press practices, and artificial aging; residual stress; cloudy finish; and white etch bloom.
