  • Publication number: 20250143139
    Abstract: A titanium alloy foil, wherein when a thickness is represented by t, the t is 0.005 mm or more and 0.200 mm or less, in X-ray diffraction intensities obtained when X-ray diffraction is performed on a surface, a peak intensity of a 200 plane of a crystal of a body-centered cubic structure is 5.0 times or larger a maximum peak intensity from other crystal structures, in X-ray diffraction intensities of the crystal of the body-centered cubic structure among the X-ray diffraction intensities, the peak intensity of the 200 plane or a peak intensity of a 211 plane is larger than a peak intensity of a 110 plane, and a tensile strength is 1,000 MPa or more and 1,800 MPa or less.
