PHOSPHORUS DEOXIDIZED COPPER PLATE EXCELLENT IN BRAZABILITY AND PRESS WORKABILITY, AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a phosphorus deoxidized copper plate excellent in brazability and press workability, and a method for manufacturing the same. ! SOLUTION: The phosphorus deoxidized copper plate excellent in brazability and press workability contains P of 0.004-0.040 mass% and the remainder consisting of copper and inevitable impurities. A crystal orientation on the surface of the plate has 1.3-2.3 of a numerical value of I{200}/(I{220}+I{420}) when the X-ray diffraction intensity of a {200} crystal plane is set to I{200}, the X-ray diffraction intensity of a {220} crystal plane is set to I{220} and the X-ray diffraction intensity of a {420} crystal plane is set to I{420}. A surface roughness Ra on the surface of the plate is 0.1-0.3 μm, and the degree of steepness on the surface of the plate is 0.4% or less. ! COPYRIGHT: (C)2015,JPO&INPIT
