- Al-Zn alloy comprising precipitation with improved strength and elongation and method of manufacturing the same

摘要

The present invention relates to an aluminum-zinc (Al-Zn) alloy containing zinc in an amount of more than 20 parts by weight based on the total weight of the alloy and having strength and elongation including a discontinuous precipitate or lamellar precipitate And more particularly to an improved aluminum-zinc alloy. According to the present invention described above, the tensile strength and elongation of the aluminum-zinc alloy can be simultaneously improved.
