Brass foundries have typically seen an increase in scrap rates due to castings failing leak testing since the conversion from leaded brass alloys to no-lead brass alloys. In most cases, foundries have not made significant changes to the gating systems to address this issue with the no-lead alloys. While turbulent gating systems may not have been associated with scrap issues with leaded alloys, they may be contributing to the struggles of making pressure-tight no-lead castings. This is an investigation of the effect that turbulent gating systems have on the C89833 low-lead brass alloy.
