7075-T6 Aluminum
Aluminum 7075-T6 has been precipitation-hardened. It has undergone the same T6 tempering process as 6061-T6 Aluminum. As zinc is the main alloying component, 7075 aluminum is one of the strongest commercially available aluminum alloys, with strength that is equivalent to steel alloys. Among the alloys on this list, 7075-T6 has the highest shear strength and is also the strongest aluminum alloy. This is why 7075 aluminum is also known as aerospace aluminum or aviation-grade Aluminum. The downside to this extreme strength is that 7075 aluminum has worse corrosion resistance than lesser aluminum alloys.
Aluminum 7075-T6’s is beneficial as it has very high tensile and shear strengths. Also, it is easily paintable and finish-accepting. Plus, it is Formable and has good fatigue resistance. But it is high in price, lower corrosion resistance, and fair machinability.
Common uses of Aluminum 7075-T6:
- Frameworks for aircraft and other structural components
- Bikes frames
- Tooling Devices
- Marine and automotive structural components
- Injection molds for plastic
7050 Aluminum
7050 aluminum is strong and resistant to abrasion erosion — exfoliation is a form of corrosion between grains that affects the metal within or adjacent to the grain boundaries. The alloy 7050 is durable and resistant to fatigue. Al, Zn, Cu, and Mg make up the majority of its composition. Similar to other alloys, zinc boosts strength, while magnesium makes the substance harder. Copper is added to an alloy to boost its strength and facilitate precipitation hardening.
Thus, it has many benefits, such as being Heat-treatable, increased fracture toughness, and high power. Also, it has excellent resistance to stress-corrosion cracking and exfoliation corrosion, and even at increasing thicknesses, materials are machinable and formable. However, because the weld joints are weaker than 7075 aluminum, it is not recommended for welding and diminished electrical conductivity.
Common uses of Aluminum 7050:
- Aircraft structural components
- Rock climbing equipment
- Bicycle parts
A Head-to-Head Comparison of 6061 and 7075 Aluminum
It’s time to compare 6061 and 7075 aluminum alloys now that we’ve dived into their nuances. With the help of this comparison, you will be able to see how these two alloys vary from one another and where each one excels, providing you with the knowledge you need to make wise choices best aluminum extrusion profile services.
1. Stability and Strength
7075 aluminum is the strongest member of the aluminum family and, therefore, holds the title. This aluminum alloy is one of the strongest that can be commercially produced today and is, therefore, suitable for demanding applications where strength is of utmost importance.
6061, on the other hand, has strength for many applications, although not as strong as 7075 aluminum. It is a more versatile choice on account of its strength, good corrosion resistance, and weldability.
2. Machinability and Weldability
Aluminum 6061 is the undisputed champion when it comes to welding. It is a top choice for constructions that require welding due to its exceptional weldability. Due to its lower strength and better machinability, 6061 aluminum is appropriate for applications requiring intricate and thorough machining.
3. Resistance to Corrosion
Both alloys offer strong corrosion resistance. But 6061 aluminum offers better resilience, especially against corrosion. For uses that will be exposed to corrosive conditions, it is a preferable option.
4. Cost
In general, 6061 aluminum costs less than 7075 aluminum. The increased strength and tougher machinability of 7075, which makes it more expensive to manufacture, are to blame for this price disparity.
Conclusion: Which One is Right for You in 2025?
There is no “best” alloy to offer the most perfect application. If your company is aiming for maximum strength, select 7075-T6. Other than that, if your preference is cost-effectiveness, then 6061-T6 is more affordable and corrosion-resistant.
As the industry is transforming towards performance optimization, lightweight abilities, and sustainability, understanding the abilities of alloys is important.
