Titanium rod is α alloy contains a certain amount of stable α phase elements, balanced state mainly by the α phase composition. Α alloy with small specific gravity, good thermal strength, with good weldability and excellent corrosion resistance, Titanium Bar the disadvantage is low room temperature, usually used as heat-resistant materials and corrosion-resistant materials. (Ti-8Al-1Mo-1V) and α-alloys (Ti-2.5Cu) with small amounts of compounds are usually divided into all-α alloy (TA7), near-α alloy (Ti-8Al-1Mo-1V)

Titanium rod manufacturing process:
Hot forging - hot rolling - car light (polished)
2. Hot rolling: The rolling process is carried out at a temperature higher than the recrystallization temperature. 3. burnishing: polishing is the process of cutting the surface of a metal part with a special grinding wheel (or tape) with abrasive abrasive. Polishing can remove parts of the surface of the burr, corrosion, scratches, welding tumor, weld, trachoma, oxide and other macro defects to improve the smoothness of parts and plating quality.
