TITANIUM COPPER AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide titanium copper improved in spring characteristics after bending. SOLUTION: The titanium copper is a copper alloy containing 2.7 to 3.7mass% Ti and consists of the balance Cu and inevitable impurities, in which a work hardening coefficient is≥0.1 and the difference in volume resistivity (ρ:μΩcm) before and after heat treatment to water-cool the alloy after heating for 10 minutes at 900°C is 25 to 45.
