Strength enhanced anodizable aluminum alloy and improved anodizing process

The present invention relates to an aluminum alloy, and more specifically, relates to an anodizable aluminum alloy, which minimizes elements that adversely affect anodizing for realizing anodizing and improves its strength in a state where harmful elements are eliminated. The aluminum alloy for anod...

Zusammenfassung:	The present invention relates to an aluminum alloy, and more specifically, relates to an anodizable aluminum alloy, which minimizes elements that adversely affect anodizing for realizing anodizing and improves its strength in a state where harmful elements are eliminated. The aluminum alloy for anodizing according to the present invention comprises: 5.0-6.0 wt% of zinc (Zn); 1.0-2.5 wt% of magnesium (Mg); 0.01-0.6 wt% of copper (Cu); 0.1-0.2 wt% of iron (Fe); and the remaining of aluminum (Al). 본 발명은 알루미늄 합금에 관한 것으로써, 보다 구체적으로는 아노다이징 구현을 위해 아노다이징에 악영향을 미치는 원소를 최소화하고 인체 유해 원소를 배제한 상태에서 그 강도가 향상된 아노다이징용 알루미늄 합금에 관한 것이다. 본 발명에 따른 아노다이징용 알루미늄 합금은 아연(Zn) 5.0 내지 6.0중량%, 마그네슘(Mg) 1.0 내지 2.5중량%, 구리(Cu) 0.01 내지 0.6중량%, 철(Fe) 0.1 내지 0.2중량% 및 잔부의 알루미늄(Al)을 포함한다.
