This course comprises 8 weekly sessions, covering the major measures of aluminium molten metal quality important for wrought aluminium alloys: dissolved hydrogen, non-metallic inclusions and alkali metals. In each case, the course covers the origins of that impurity, and the downstream impacts if levels are too high. The measurement methods and their limitations are reviewed, before addressing the technologies available to reduce impurities to acceptable levels. Each session consists of a seminar and an associated workshop.
The course can be attended as a standalone course or seen as the second in a trilogy of related courses. It is preceded by Scrap Recycling and Melting, and will be followed later in 2026 by DC Casting.
