Product Capacities of Alloy 7050

Typical Uses

7050 aluminum alloy is a high-performance material prized in the aerospace industry for its exceptional strength, fatigue resistance, and resistance to stress corrosion cracking.
This unique combination makes it the go-to choice for critical aerospace structures like wing skins, fuselage frames, and bulkheads. Its good machinability allows for complex shapes, while its weldability is limited.

FAQs

What is the Difference Between 7050 and 7075 Aluminum Alloy?

7075 aluminum contains higher levels of zinc, giving it superior strength and hardness. However, 7050 aluminum offers better stress corrosion cracking resistance and toughness due to its additional alloying elements like magnesium and copper.

What is the Difference Between 6061 and 7050 Aluminum?

6061 aluminum is primarily alloyed with magnesium and silicon, providing good corrosion resistance, weldability, and machinability. In contrast, 7050 aluminum, which includes zinc, magnesium, and copper, offers higher strength and better stress corrosion resistance.
