Hi Mary, Normally the cad software will have a tool to calculate the
metal weight? If not, I have only had pieces cast in stainless steel
a couple of times. But I seem to remember it was more of a flask
charge than a charge by material weight? If you know the dimensions
of the object I think you will probably be able to get a quote on the
cost that way. I would suggest you call the good folks at Techform
Casting and ask them. Techform Advanced Casting Technology, 5558-D SE
