How mechanical properties of aluminum 6061 vs 7075 vary?


The mechanical properties of any metal are an important point to be discussed. The metal can bear the strength of external forces that are acting on them. The mechanical properties of aluminum 6061 and 7075 vary. In some properties 6062 is better and in some 7075. You can request a quote to get further information about the topic and have your knowledge strength about the properties of aluminum 6061 and 7075.

The mechanical properties of aluminum 6061 and 7075 include malleability, strength, conductivity, and other points. This article is focused to write about these properties. You will get good information from this article. Some of them are as under.

Metal properties of Aliminium 6061 vs 7075

Alluminium 6061 has 6XXX series and alluminium 7075 has 7XXX seies. Aluminum 6061 is best as compared to aluminum 7075 because of many factors. But in some cases, the mechanical properties of the aluminum 6061 and the aluminum 7075 vary.

Yield strength

The first factor due to which aluminum 6061 is better than aluminum 7075 is yield strength. The aluminum 7075 has higher yield strength as compared to the aluminum 6061 alloys. The aluminum 7075 can withstand impact and more pressure without deformation. The yield strength of aluminum 7075 is because of its heat treatment and its chemical composition. The aluminum 6061 is not completely weak because of its yield strength of 276 MPa.

Thermal conductivity

The alloys of aluminum are good conductors of heat in general. In some cases, the heat capacity of the aluminum 6061 and the aluminum 7075 varies. This is due to the heat treatment and their chemical composition. The thermal conductivity of aluminum 6061 is higher than that of aluminum 7075.

Electrical reactivity

Both the alloys of aluminum, the aluminum 6061 alloy, and the aluminum 7075 alloy are good conductors f heat because they have low electrical reactivity. So, both the aluminum 6061 and the aluminum 7075 are best for electrical use.


The elasticity of the material shows you the resistance to deformation and the resilience of the material. Both alloys of aluminum have similar resistance to deformation. These alloys of aluminum also correlate to the material stiffness.

Material hardness

The hardness of the material shows how much they resist deformation by penetration, Indenteration, or by other means.

Both the aluminum 6061 and the aluminum 7075 are hard enough to resist pressure. The aluminum 7075 alloy is harder than the hard aluminum 6061 alloys.

Corrosion resistance

Aluminum 6061 is more corrosion resistive than that aluminum 7075 alloys. The reason for this is not far-fetched. The amount of copper in aluminum 7075 is more than that in aluminum 6061 alloy.

Temperature resistance

The temperature resistance of aluminum 6061 and 7075 is dependent on the melting point of these alloys. The melting point of both these metals differ and their temperature resistance varies.

The melting point of 7075 is 477 to 635 degrees while the melting point of 6061 is 582 to 652 degrees. As aluminum 6061 has a high melting point so its temperature resistance is also high these are some of the metallic properties of aluminum. These properties vary from one metal alloy to another


Aluminum alloys exist in different forms and all of them are best to be used. The aluminum 6061 is preferred to be used in most of the projects. But if you are talking about their mechanical properties in both cases it varies. But the applications of these two metals are outstanding. They have been used in the manufacturing of such great things that no other metal could provide an effective result. The strength and the weakness of the aluminum 6061 and 7075 however vary.
