HIGH-STRENGTH COPPER TITANIUM PLATE AND PRODUCTION METHOD THEREFOR

摘要

The present invention is to provide a titanium strength , electric conductivity and excellent bending workability and a method of manufacturing the copper plate . Titanium and high-strength copper plate containing Ti of 2.5 to 4.0 mass % , the balance being made of Cu and inevitable impurities , wherein a tensile strength of more than 950 , 0.2% proof stress and the tensile strength is 0.9 times or more , the bending axis is the rolling direction and such that when parallel to the W bending test was carried out , the ratio (MBR / t) is less than 1.0 of the minimum bending radius of the crack is not generated (MBR) and the thickness (t).
