Abstract (en)
[origin: EP3845676A1] Provided is a titanium copper plate which is a non-mill hardened material of titanium copper which is subjected to a heat treatment after pressing and which has good springiness and dimensional stability after the heat treatment. The titanium copper plate contains from 2.0 to 4.5% by mass of Ti, the balance being copper and inevitable impurities, wherein the titanium copper plate has a tensile strength in a rolling parallel direction of 750 MPa or more, and a conductivity of from 4.0 to 8.0% IACS, and wherein the titanium copper plate has a spring limit value of 800 MPa or more in the rolling parallel direction when subjected to a heat treatment at 400 °C for 2 hours, and a thermal expansion/contraction ratio of 100 ppm or less in the rolling parallel direction when subjected to a heat treatment at 400 °C for 2 hours.
