Beschreibung
Zusammenfassung:	The present invention relates to a zinc (Zn) alloy excellent in softening resistance, and more specifically, to a zinc (Zn) alloy capable of obtaining excellent softening resistance by adding magnesium (Mg) as an alloy element. According to the present invention, the zinc alloy having excellent softening resistance is composed of 0.0005 to 0.05% by weight of magnesium (Mg) and the rest is composed of zinc (Zn) and other unavoidable impurities so that the zinc alloy has a tensile strength of 120 MPa or higher at room temperature or after heat treatment at a temperature of 150C or lower, and has softening resistance of 95% or higher at a temperature of 150C. 본 발명은 내연화성이 우수한 아연(Zn) 합금에 관한 것으로서 특히, 마그네슘(Mg)을 합금원소로 첨가함으로써 우수한 내연화성을 얻을 수 있는 아연(Zn) 합금에 관한 것이다.본 발명에 의한 내연화성이 우수한 아연합금은 마그네슘(Mg) 0.0005~0.05중량% 및 나머지는 아연(Zn)과 기타 불가피한 불순물로 아연합금이 구성됨으로써, 150℃의 온도에서 내연화성이 95% 이상이고 상온 인장강도와 150℃ 이하의 온도에서 열처리 후에 측정된 인장강도가 120MPa 이상인 특징을 가지고 있다.
