Product Capacities of Alloy 7005

Typical Uses

In the automotive industry, 7005 aluminum alloy is widely utilized for its high strength-to-weight ratio and excellent fatigue resistance. This makes it ideal for manufacturing critical components such as chassis parts, engine mounts, and suspension systems.
The alloy’s lightweight nature reduces the overall weight of vehicles, enhancing fuel efficiency and performance. Additionally, its good corrosion resistance ensures the durability and longevity of the parts, even in harsh environments.

FAQs

What is the Difference Between 6061 and 7005?

The main differences between 6061 and 7005 aluminum alloys lie in their composition and mechanical properties. 6061 aluminum is primarily alloyed with magnesium and silicon, offering good corrosion resistance, weldability, and machinability. In contrast, 7005 aluminum is alloyed with zinc, providing higher strength and hardness. However, 7005 is more expensive due to the higher cost of zinc compared to magnesium and can be more difficult to machine.
