Abstract
A titanium sheet has a chemical composition containing, in mass %, Cu: 0.1 to 1.0%, Ni: 0.01 to 0.20%, Fe: 0.01 to 0.10%, O: 0.01 to 0.10%, Cr: 0 to 0.20%, the balance: Ti and unavoidable impurities, and satisfying 0.04≤0.3Cu+Ni≤0.44%. The average grain size of α phase is 15 μm or larger, and an intermetallic compound of Cu and/or Ni, and Ti is at 2.0 volume % or less. This titanium sheet has excellent workability and high strength.
