Grade 1 Titanium Disk is a high-purity, unalloyed titanium form distinguished by its exceptional ductility, corrosion resistance, and biocompatibility. Known for being the softest and most formable among the commercially pure titanium grades, it offers excellent cold workability and deep draw capabilities, particularly beneficial for complex shaping and fabrication. This disk form is vital across medical implants, marine systems, and chemical processing due to its outstanding tolerance to seawater and chloride-rich environments. In specialized applications, it serves in plate heat exchangers, orthopedic plate systems, and as cladding in high-purity vessels. The disk’s superior performance under cryogenic and elevated temperatures, from -184°C to 540°C, supports use in aerospace insulation layers and corrosive reactor components. Its importance in material science research stems from its predictable behavior under forming and surface treatments, such as laser alloying, making it a reliable substrate for coating and functionalization studies. This disk’s unique blend of purity and mechanical reliability secures its value in advanced manufacturing and biomedical innovation.
