6061 t6 aluminum vs 7075 aluminum

6061-T6 and 7075 are both popular aluminum alloys, and while they share some similarities, there are also significant differences, particularly in strength, hardness, and applications. Here’s a brief comparison:

1.Strength comparison between 6061-T6 and 7075:

6061-T6 Aluminum Sheet Alloy: Has good strength and is often used in structural applications. But compared to 7075, overall it is not that strong.7075:Aluminum sheetAlloy 7075 is known for its high strength, making it suitable for applications where strength is a key factor.

2.Aluminum 6061 t6 aluminum vs 7075 hardness:

6061-T6 is less hard than 7075, which may be an advantage in some applications where machinability and formability are more important than maximum strength. 7075 aluminum plate has higher hardness because it contains zinc as an alloying element. This makes processing more challenging but provides greater strength.

3.6061 t6 aluminum vs 7075 aluminum machinability comparison:

6061-T6 aluminum plates are generally easier to process and form, and are well suited for the production of complex shapes. 7075 aluminum plate is more difficult to process than 6061 due to its higher hardness.

4.6061-t6 aluminum vs 7075 corrosion resistance:

Aluminum sheet Both alloys 6061 and 7075 have good corrosion resistance, but 6061 may have a slight advantage in some environments due to the absence of zinc, which may be the source of galvanic corrosion in 7075.

5.Application comparison of aluminum plate 6061 t6 and 7075:

6061-T6 aluminum plates are commonly used in structural parts, bicycle frames, aerospace accessories, ship parts, and general mechanical parts.7075 aluminum sheet is widely used in aerospace applications, highly stressed structural components, and parts requiring high strength and low weight.

6.Aluminum 6061 vs 7075 Ingredients:

The main components of 6061 series aluminum alloy are magnesium and silicon, with zinc accounting for a very low proportion. The zinc component of the 7075 series aluminum alloy accounts for a relatively large proportion, reaching 6%. In addition, 7075 aluminum plate has a slightly higher magnesium content and also adds more copper to its chemical composition.

7.6061-t6 aluminum vs 7075 price:

Because 7075 aluminum alloy has high strength and zinc content, its price is relatively high. The 6061 aluminum alloy is relatively economical and affordable.

8.Aluminum 7075 vs 6061 practicality:

Since 7075 aluminum alloy contains a high proportion of other metals and is difficult to weld, it is generally not used as frame material. Since 6061 aluminum alloy contains a low proportion of other metals, it can be processed in various ways to increase its strength and reduce wind resistance. It can even be piped three times to reduce weight. Therefore, 6061 aluminum alloy has good practicality.

9.Comparison of density between 6061 aluminum plate and 7075 aluminum plate

There is a difference in density between 6061 aluminum alloy and 7075 aluminum alloy. 6061 aluminum alloy is a common aluminum alloy, mainly composed of aluminum, magnesium and silicon, with a density of approximately 2.70g/cm³ or (2700kg/m³). The 7075 aluminum alloy is a high-strength aluminum alloy, mainly composed of aluminum, zinc, copper, magnesium and other elements. Its density is approximately 2.81g/cm³ or (2810kg/m³). Therefore, from a density perspective, the density of 7075 aluminum alloy is slightly higher than that of 6061 aluminum alloy.

10.Comparison of melting points between 6061  and 7075 aluminum plate

The melting points of 6061 aluminum alloy and 7075 aluminum alloy are the same, both around 660°C.

In summary, the choice between 6061-T6 and 7075 depends on the specific requirements of the application. If high strength and hardness are critical and machinability is not a major consideration, 7075 may be the first choice. If machinability, formability and strength balance are important, then 6061-T6 may be more suitable.
