7050 aluminum round bar
7050 Aluminum round bar Vs 7075 aluminum round bar
7050 and 7075 are both high-strength aluminum alloys commonly used in aerospace and other high-performance applications.
7050 aluminum round bar is a heat-treatable alloy with good strength and toughness. It has high strength-to-weight ratio and good resistance to stress corrosion cracking. It is often used in aerospace applications, such as aircraft structures and components.
7075 aluminum round bar is also a high-strength alloy with excellent strength and toughness properties. It has good machinability and corrosion resistance. It is commonly used in aerospace, defense, and automotive industries for applications requiring high strength and durability.
In general, 7075 aluminum round bar is stronger and more durable than 7050 aluminum round bar.
However, 7050 aluminum round bar may be preferred in certain applications where stress corrosion cracking resistance is important.
The choice between the two alloys will depend on the specific requirements of the application.
7050 aluminum round bar is available in various tempers, such as T74511, T76511, and T73511. These tempers indicate different levels of heat treatment and cold working that affect the mechanical properties and performance of the alloy.
