| Abstract: | A new rare-earth copper alloy powder for 24K gold imitation is prepared. The optimal composition of the new alloy produced in the pilot experiment is Zn 20 % - 27 %, Al 0.5 % - 2.0 %, Ni 0.5 % - 2.0 %, Sn 0.1% 0.25%, In0.2%-0,5%, Si0.2%-1.5%, Re0.1%-0.3%, Cutherest. In, Re, Al and Si as alloying elements provide somewhat effect on improvement of the color, metallic gloss of the 24K gold imitation rareearth copper alloy powder. The color of the alloy with 0.15% rare-earth content is kept for 130h in man-made sweat liquor. The brightness of the alloy is also increased by the alloying element of Re. The new rare-earth copper alloy for 24K gold imitation has excellent deformability. |
