Abstract
자동차 외판 혹은 바퀴용 판재등에 사용되는, 성형후 베이킹 도장이 시행되는 알루미늄 합금판부재의 성형성과 가열경화성을 높이는 것을 목적으로 한다.
Al-Mg-Si계 합금판재를 480℃ 이상으로 가열하여, 열간압연을 행할 때 360℃-450℃의 온도범위에서 15분이상 노출시키는 일없이 360℃ 이하의 온도범위에서 압연을 종료시키며, 다음에 실온에서 1시간 이상의 자연시효를 시행하여, 도전률을 35∼55% 1ACS의 범위로 한 후, 180∼300℃의 온도범위에서 10초 이상 10분 이내의 가열처리를 도전율이 실질적으로 저하하지 않는 범위에서 시행함과 동시에, 상기 가열처리 전후의 판면에 평행한 면의 평균 결정 입자지름이 90㎛ 이하이며, 압연방향과 그 직교방향의 결정입자지름의 길이비(압연방향길이/직교방향길이) 평균이 0.5∼4의 사이이며, 재료중 Si를 포함한 화합물의 평균최대길이를 10㎛ 이하로 한다.
