抄録

For making the substitution of the KINPARA, we has set the 'Ag-4.5wt%Si' as the base-alloy, and we has made the 15 kinds alloys which had been alloyed by the addition of the each 'Au ,Ag, Pd' until 20wt%. We has measured of the mechanical properties and color difference. As the result, the additional 'Au' has made an upward tendency to the tensile-strength and to the elongation, the value of color difference has made up ward to KINPARA represented decrease following it. Having been caused the segregation by the additional 'Pt' into the base-alloy, the value of hardness has represented upward tendency.
