Abstract
【解決手段】Feを含み、500℃で1分間焼鈍した後のCube方位の方位密度が50%以下であり、且つ更に500℃で1分間焼鈍した後の平均結晶粒径が30μm以下である耐熱性に優れた銅合金である。この様な銅合金は、Feを含む銅合金を熱間圧延したのち冷間圧延して冷延銅合金を製造する際に、熱間圧延と最終冷間圧延の間に冷間圧延と焼鈍を少なくとも2回ずつ実施すると共に、1回当りの冷間圧延を50〜80%の加工率で行い、最終冷間圧延時の加工率を30〜85%とすることによって製造できる。
【選択図】なし
Description
下記表1に示す化学成分の銅合金を各々コアレス炉で溶製し、半連続鋳造法で造塊して厚さ50mm×幅200mm×長さ500mmの鋳塊を得た。得られた各鋳塊を加熱してから厚さ12mmにまで熱間圧延したのち面削し、更に冷間圧延と焼鈍を繰返し、最後に最終圧延を行って厚さ約0.2mmの銅合金板を得た。
