The chemical composition of 7050-T7451 aluminum alloy is characterized by its high zinc, copper, and magnesium content, in addition to aluminum as the base metal. Zinc is the primary alloying element, significantly increasing the alloy’s strength. Copper and magnesium further enhance the strength and contribute to heat treatability. Zirconium is added to control grain structure and improve fracture toughness and fatigue resistance. The low limits on other elements like silicon and iron are important to maintain the alloy’s high performance characteristics, especially in demanding applications where strength and toughness are critical.
7050 Aluminum Temper Comparisons
Understanding the different types of 7050 aluminum is important for choosing the right material for a specific use. Each type shows how the alloy has been treated with heat. This treatment leads to different mechanical properties.
T7451 is noted for its good balance of strength, toughness, and resistance to stress corrosion cracking. On the other hand, popular tempers like T7651 and T351 have their own benefits depending on the needs of the specific application.
T7651 Vs. T351 Vs. T7451
When choosing the best temper for 7050 aluminum, you need to think about what your application needs. T7651, T351, and T7451 are some of the most common tempers. Each one has special features.
The main differences between 7050-T351, T7451, and T7651 aluminum are because of how they are heated. This heating changes how well they resist rust and cracking from stress, but their strength stays about the same.
T351 is the basic version and is not as good at resisting rust and stress cracks. T7451 is heated to be much better at resisting stress cracks without losing much strength. T7651 is heated even more to be the best at resisting rust and stress cracks, but it might be a little weaker than T7451 and T351. If you need good strength, any of them work, but if you need to prevent rust and cracks, especially in tough conditions, T7451 or T7651 are better choices.
