Fine Proofing Alloy
1 lb. Cake of Fine Proofing Alloy Keynote of Applications Growth after casting is +.0002" after 6 minutes. However, after 30 minutes the change is .0000 (zero), so that this is the best time for removal and inspection. After 1 hour and up to 21 days, the change is between .0001" and .0002" on the minus side.
