Titanium has plasticity, the elongation of purity titanium can be up to 50-60%, and the reduction of area can be up to 70-80%. That makes the production of titanium capillary tube. Forging and rolling the secondary melting titanium ingots into the tube billets, then stretch the tube billet for several times until the titanium capillary tube formed. Due to the good compatibility with human body and corrosion resistance, titanium capillary tube is widely used in the medical industry, including the human body implants, medical equipment internal precision parts, etc.
