High Strength Aluminous Porcelain (IEC 60672 Type C-130)
C-130 aluminous porcelain is a grade of engineering porcelain. The graph bars on the material properties cards below compare C-130 aluminous porcelain to other oxide-based engineering ceramics (top) and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
