2011 Aluminum round bar rod

Characteristics of 2011 Aluminum round bar rod

2011 is a typical hard aluminium alloy in the aluminium-copper-magnesium system. It is a cold-drawn or refined aluminium product. Because of the addition of lead and bismuth, it is the most free-cutting alloy product with excellent machinability.
The available states are: T3, T4, T8, etc.
 
Applications of 2011 Aluminum round bar rod
