Abstract
이와 같은, 주단조용 알루미늄 합금 및 이를 이용한 자동차 샤시구조 부품의 제조방법으로 제조된 부품은, 주조열간크랙방지, 내부수축결함방지 및 결정립사이즈 150 이하로 제어 할 수 있으며, 특히, 실형상으로 부품 주조는 기존의 6000계열 열간단조용 합금 제조공정인 연속주조빌렛, 균질화처리, 절단등의 공정을 절감할 수 있어 제품의 회수율 및 제조공정 단순화로 제조원가 10% 절감을 할 수 있다. 이에 자동차 샤시구조용 부품에 실형상 주단조용 고강도 알루미늄합금을 적용하면 기계적특성이 우수하여 설계중량을 절감할 수 있으며, 기존의 열간단조공정 대비 단순 제조공정으로 원가절감 등의 효과를 제공한다.
