Calcium related shrinkage in ALSi alloy
Calcium related shrinkage in ALSi alloy
(OP)
Casting tech manager of mid size alloy wheel plant Australia.
Does anyone have suggested reading/articles/experiences on the above,having issues with fluctuating calcium % seems to tie in with increases in shrinkage levels in the casting especially the thinner rim sections.
Can calcium be manipulated apart from dilution?Ive been told adding phospourus to a Ca 5 to P 1 ratio will help.
Thank
