General Description:  

Best mechanical properties of any Copper alloy which improve at sub-zero temperatures as low as -200C. Hardened by heat treatment this alloy machines best in the quarter hard cold work condition. Uses include springs of all kinds where high strength and corrosion resistance are important, resistance welding electrodes, dies and high strength, corrosion resistant tubing.
