Material Notes:
Specifically designed for high production injection and blow mold applications, QC-10 offers outstanding strength, stability, and durability. Its improved alloy composition provides outstanding, 1"- 24" thick section strength and hardness equal to that of rolled plate. Its quench insensitive microstructure allows minimal strength drop-off and excellent machinability.Information provided by Alcoa.
