Description
すなわち、Au:30〜46mass%、Ag:5〜11mass%、Pd:30〜50mass%、Ir:0.05〜0.5mass%、Sn:5〜8mass%、In:0〜2mass%及びGa:1mass%以下(ただし、Sn、In及びGaの合計量は10 mass%まで)とする。
実施例と参考例の合金の硬さは、265〜303HVと比較例の合金よりも大きく、耐力も641〜660MPaと比較例合金よりも高い値を示しながら、伸びも9〜11%であり、優れた機械的性質を有していた。熱膨張係数は、13.8〜14.2×10-6K-1であり、プレス成形法に適するとされる範囲内であった。プレス成形後の状態は、いずれもクラックは見られず、かつ、フレームとしての変形も確認されず、プレス成形法として十分適合した。さらに、陶材変色も認められなかった。
