The applicability of the permanent mold casting process for the new type of lead-free bronze with dispersed sulfide was evaluated by comparison with other conventional copper alloys, such as leaded bronze, leaded brass, and lead-free bronze containing bismuth. The copper alloys were cast into the permanent mold for the solidification cracking test. The relationship between the degree of cracking and solidification temperature range was examined. <br> The new lead-free bronze with dispersed sulfide was more unbreakable than the other copper alloys. The smaller the solidification temperature range, the harder it was for solidification cracking to occur. Comparison of the new lead-free bronze with the leaded bronze and lead-free bronze containing bismuth indicated differences in the dendrite shape near the fracture and distribution of the residual melt segregated to one area towards the end of the solidification. The new lead-free bronze may also have a solidification morphology that makes it more difficult to crack, allowing it to be applied to permanent mold casting compared to other copper alloys. Its level of applicability is more or less the same as brass castings.
