{{Inuse}}


常見的型號有: '''7075-O''', '''7075-T6''', '''7075-T651'''
'''7075''' is an [[aluminium]] [[alloy]], with [[zinc]] as the alloying element. It is strong, with good fatigue strength and average machinability, but is not weldable and has less resistance to corrosion than many other alloys.


== 基本性質 ==
It is commonly produced in several heat temper grades, '''7075-O''', '''7075-T6''', '''7075-T651'''.

As with all aluminum alloys, 7075 has a [[specific gravity]] of 2.73 (0.098 lb/cubic inch).

== Mechanical properties ==
The mechanical properties of 7075 depend greatly on the temper of the material.
