Investigating the Effects of Turbulent Gating on C89833 Material

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.
