high strength and glossy aluminum alloy with excellent anodization and moldability

The present invention relates to a high gloss high strength aluminum alloy with excellent anodizing and molding capable of performing hard and soft anodizing through a component and tissue control even if a content of Zn in an Al-Zn-Mg(-Cu)-based alloy is not lowered, capable of being anodized in any color which can be realized by dyes such as silver, gold, pink, blue, purple, black, and the like, and capable of being realized not only in dark colors but also in bright colors. The present invention comprises: 0.2 wt% or less of Si; 0.2 wt% or less of Fe; 0.03-0.1 wt% of Cu; 0.01-0.2 wt% or less of Mn; 1.0-2.0 wt% of Mg; 0.001-0.05 wt% or less of Cr; 5.0-5.5 wt% of Zn; 0.001-0.1 wt% of Ti; 0.001-0.1 wt% of Zr; and a remaining balance of Al. 본 발명은 Al-Zn-Mg(-Cu)계 합금에서 Zn의 함량이 낮아지지 않더라도 성분 및 조직제어를 통해 경질 및 연질 아노다이징이 가능하고, 실버, 골드, 핑크, 블루, 퍼플, 블랙 등 염료에 의해 구현할 수 있는 모든 색으로 아노다이징이 가능하며, 어두운 색 뿐만 아니라 밝은 색상도 구현 가능한 아노다이징 및 성형이 우수한 고광택 고강도 알루미늄 합금에 관한 것이다.
