@@@@On account of such problems occurring in the casting process as shrinkage porosity ,oxide inclusions, coarse grains,an 18K yellow gold alloy was developed and its castability was evaluated .The results show that through the multiple alloying,the appropriate component matching and casting process ,the experimental 18K yellow gold alloy has excellent liquidity,fine grain,high density and few oxide inclusions ,and it is not easy to form shrinkage porosity or crack.Therefore,the alloy has excellent casting performance and is suitable for jewelry casting materials .
