Abstract

본 발명은 신동공장에서 사용되고 있는 Si을 사용하여 탈산을 촉진시키고, Cr, Sn 등의 합금을 구성하는 원소를 함유시켜도 제조에 불편이 없고, 대기, 비산화 또는 환원분위기에서도 용해주조가 가능한 성분으로 조성하여 인장강도를 떨어뜨리지 않으면서도 고전도성을 겸비함과 함께 적정한 고가공성을 갖게하고, 또한 동합금 소재를 제조함에 있어 Cr을 Cu 매트릭스에 충분히 고용시키기 위한 열간압연 종료 후의 고온 용체화를 실시하지 않으므로서 공정의 단축화로 저렴한 제조원가를 갖게 하는데 적합한 동합금에 관한 것이다. 본 발명의 구성은 100 중량%로서, Cr 0.2~0.4 중량%, Sn 0.05~0.15 중량%, Zn 0.05~0.15 중량%, Mg 0.01~0.30 중량%, Si 0.03~0.07 중량% 이고, 잔부가 Cu 및 불가피한 불순물로 조성됨을 특징으로 하는 고인장강도, 고가공성, 고전도성을 갖는 동합금으로 이루어지고, 또한 본 발명은 상기한 조성의 용탕을 얻는 단계, 주괴를 얻는 단계, 상기 주괴를 900~1000℃ 가열하여 열간압연하는 단계, 냉간압연하는 단계, 400~500℃에서 2~8시간 1차 시효처리하는 단계, 냉간압연하는 단계, 370~450℃에서 2~8시간 2차 시효처리하는 단계로 이루어짐을 특징으로 동합금의 제조방법으로 이루어진다.
