F condition: Manufacturer-reported typical single values, not a sample mean or range. The source says properties reflect cooling after injection (water quench) and depend strongly on the casting process; wall thickness and sample size are not reported.

F+PB condition: Manufacturer-reported typical single values, not a sample mean or range. The source says properties reflect cooling after injection (water quench) and depend strongly on the casting process; wall thickness and sample size are not reported.

Chemical composition

Reported weight-percent bounds. A blank lower bound means only an upper threshold was reported.

Alcoa reports C611 chemistry in wt%; single values are maxima. Explicit < signs remain strict upper bounds. Others (each) and Others (total) are the source labels.
