2A11 Aluminum Sheet

2A11 Aluminum Sheet

 

2A11 Aluminum Sheet is the earliest hard aluminum. Commonly known as standard hard aluminum. It has medium strength. The 2A11 aluminum sheet has good plasticity in the state of annealing, rigid quenching and heat treatment. It can be strengthened by heat treatment. It has good spot weldability under the state of quenching and natural aging.
