What is the % of strontium to be used in ALSi10 aluminium alloy for structure modification? Is 0.02 to 0.04% gives good results in case of high pressure die castings? What are the results of excess addition? What is the retained strontium % when checked on actual casting? Gajarepramod (talk) 18:05, 17 April 2010 (UTC)
