Abstract (en)

Aluminium-lithium alloys are cast on a twin-roll caster under an inert atmosphere to give a cast slab from 2-7 mm, and preferably 2-4 mm, thick. Alloys may be of the 2000 or 8000 Series. Casting speed may be from 50-200 cm/min and the diameter of the rolls from 20-50 cm. The alloys are more easily cast with less centre-line segregation than are Al-Mg alloys of comparable long melting range. The case slabs are in a suitable form for cold rolling to make sheet.
