In this study, we investigated the influence of addition of tin on JIS CAC804 properties. When tin is added, solidus and liquidus temperature of the alloy lower, and the solidification temperature range widens. Generally, if an alloy's solidification temperature range is wide, its castability is low, but not much castability difference was observed between CAC804 containing tin and that without.
A large portion of added tin is distributed in γ phases in the form of solid solution, causing ductility to decline. Although results of erosion-corrosion resistance test differ depending on the test conditions, it is clear from the results of the tests we performed using two different solutions that tin has a function of alleviating weight loss in JIS CAC804.
