ACCPLAST 80 AL
The aluminium-contact grade: 79–85% alumina rated to 1450 °C, rammed at 6–9% water. The lower temperature rating against the standard Accplast 80 is deliberate — this grade is formulated for contact with molten aluminium, where wetting and penetration, not peak temperature, are what destroy a lining.
