process of titanium foil

      The production process of titanium foil with ASTM B265 standard, GR2 grade, and specifications of 0.127mm thickness and 304mm width starts with the selection of high-quality titanium sponge as the raw material. The titanium sponge is melted in a vacuum arc furnace or a plasma arc furnace to produce titanium ingots. The ingots are then hot rolled into plates of a certain thickness, followed by cold rolling to further reduce the thickness and improve the surface quality.

      After the desired thickness is achieved, the titanium plate is cut into the required width and length, and then subjected to annealing to relieve the residual stress and improve its formability. Finally, the titanium foil is obtained by shearing the annealed titanium plate into the specified dimensions.

      Throughout the production process, strict quality control measures are ensured to maintain the purity and uniformity of the titanium foil. The resulting product exhibits excellent mechanical and corrosion resistance properties, making it ideal for a wide range of applications in industries such as aerospace, medical, and chemical.

     The chemical composition can meet the following requirements: C ≤ 0.1%, Fe ≤ 0.2%, O ≤ 0.18%, H ≤ 0.015%, N ≤ 0.03%, and Ti ≥ 99.5%. The execution standard for these requirements is ASTM B265.

Mechanical Properties

The yield strength can be within the range of 172-241MPA, while the tensile strength should be within the range of 317-413MPA. The elongation rate should be over 30%, preferably 40% or above.

At last Surface Quality

The particle level should be 8 or better, and the surface roughness should be 10RA MAX. The surface must not exhibit scratches, pits, creases, waviness, impurities, wrinkles, cracks, or any other defects. The titanium coil must be tightly and non-stretchably packed, with intact edges and corners, and the material must be even. There should be no oxidized areas visible to the naked eye.
