What is Al Casting Grade A, B, C, ...?
(OP)
I am getting some aluminum(A319) investment castings made.
One is a bowl shaped part that will hold fuel.
I am switching from sand castings to investment.
I keep hearing people talk about grades of castings, A, B, and so on. How do I determine what grade of casting I need, or is there a chart with list of grades A, B, C,...?

The chart that Metengr referenced notes classes, but for the ASTM specifications. I believe that in those documents the Class refers to strength. That includes not only different acceptable strength levels, but also differentiates between those casting lots for which you need separately cast test bars and those for which you have to cut a test bar out of the casting.

Don't fret about speaking too soon, I suffer from the same phenomenon. Funny though, when it comes to talking with my spouse, the opposite effect happens.
Oh well… After reviewing my ASTM Specifications in the home office, Grades A, B, C and D refer to radiographic (x-ray) quality castings purchased under ASTM A 686 "Aluminum Alloy Castings, High Strength"
I would suggest going to the web site below and purchase yourself a copy of this Standard;
