摘要： There is provided a lead alloy capable of manufacturing a positive electrode for lead storage battery less likely to cause growth. The lead alloy contains 0.4% by mass or more and 2% by mass or less of tin and 0.004% by mass or less of bismuth, with the balance being lead and inevitable impurities. The diffraction intensity of a Cube orientation {001} in a pole figure created by analyzing the surface of the lead alloy by an X-ray diffraction method is 4 times or less the diffraction intensity of a random orientation in a pole figure created by analyzing a pure lead powder by the X-ray diffraction method.

摘要： There is provided a lead alloy capable of manufacturing a positive electrode for lead storage battery less likely to cause corrosion penetrating through a lead layer for positive electrode in the thickness direction. The lead alloy contains: 0.4% by mass or more and 2% by mass less of tin and 0.004% by mass or less of bismuth, with the balance being lead and inevitable impurities. When image analysis of a crystal orientation distribution map created by analyzing the surface of the lead alloy by an electron backscatter diffraction method is performed, intersection points of misorientation boundaries between crystal grains with a crystal misorientation of 5° or more and a straight line extending in one specific direction are extracted, and the distances between two adjacent intersection points among the extracted intersection points are measured, the average value of the distances is 50 um or less.
