Applicability of Permanent Mold Casting for Lead Free Bronze with Sulfide Dispersion (Post-Print Version) Yoshida, Ryoko 80330174 丸山, 徹 Maruyama, Toru 丸山 Maruyama 徹 Toru Abe, Hiroyuki Matsubayashi, Ryozo Teramura, Masakazu 00067638 Kobayashi, Takeshi (C) the World Foundry Organization Ltd. This data is permitted by WFO. copper alloy permanent mold casting lead free bronze solidification cracking sulfide dispersion The leaded bronze, the leaded brass, the lead free bronze including bismuth and the lead free bronze with sulfide dispersion were cast into the permanent mold for the solidification cracking test. The applicability of the permanent mold casting process for bronzes was evaluated with comparison of the range of the solidification temperature. The lead free bronze with sulfide dispersion was more unbreakable than the other copper alloys. There were differences of the dendrite form near by the fracture and the distribution of the residual melt segregated at a part of the end of the solidification. The lead free bronze with sulfide dispersion may have a solidification form being unlikely to crack. It dispersion is possible to apply the permanent mold castings process rather than the other copper alloys, and the applicability is almost same as brass castings. 70th World Foundry Congress 2012 (WFC 2012) held 25-27 April 2012, Monterrey, Mexico.
