7075 t6 aluminum vs 6061 both have good corrosion resistance and can maintain a long service life in different environments. Aluminium 7075 vs 6061 aluminum alloys are usually T6 heat treated to increase their strength and hardness. 7075 and 6061 aluminum alloy have high strength and hardness and can withstand larger loads.

7075 t6 aluminum vs 6061

There are some differences between 7075 t6 aluminum vs 6061 aluminum alloys in terms of composition, mechanical properties, price and practicality.


The main alloying element of 7075 aluminum alloy is zinc, with a content of up to 6%, while the main alloying elements of 6061 aluminum alloy are magnesium and silicon, and the zinc content is relatively low.

Mechanical properties:

The tensile strength and shear strength of 7075 aluminum alloy are higher than that of 6061 aluminum alloy, and it has better mechanical properties. In addition, the hardness and fatigue resistance of 7075 aluminum alloy are also relatively high.


Due to the composition and performance characteristics of 7075 aluminum alloy, its price is usually higher than that of 6061 aluminum alloy.


The low hardness and tensile strength of 6061 aluminum alloy makes it easy to process and suitable for structural parts that need to withstand moderate loads. Due to its high strength and hardness, 7075 aluminum alloy is suitable for structural parts that need to withstand high loads and impacts, such as aircraft parts and rocket launchers.


To sum up, 7075 t6 aluminum vs 6061 aluminum alloys each have their own characteristics, and there is no absolute advantage or disadvantage. The choice should be based on specific needs. If higher strength and hardness are required, 7075 t6 aluminum alloy may be more suitable; if better processability and corrosion resistance are required, 6061 t6 aluminum alloy may be more suitable.
