The main products of GR2 titanium tubes and titanium alloys include titanium tubes, titanium plates, titanium wires, titanium coils and some titanium standard parts.

Titanium has excellent properties such as low density, high specific strength, corrosion resistance, low linear expansion coefficient and good biocompatibility. Titanium alloy tubes as raw materials for titanium equipment welding and titanium parts processing are generally used in two aspects. Used for welding titanium equipment, aerospace spacecraft, military products, stationery and sports products; Third, the superfilament is directly used to control the components of the equipment for the precise instrument structure. These three USES have better requirements on the precision and surface quality of titanium and titanium alloy tubes.

At present the domestic and foreign production of titanium and titanium alloy wire mainly used is the drawing, grinding, annealing, acid and alkali washing, cutting, straightening and other processes, in the whole production process requires 20 drawing, three to four times of intermediate grinding, ten times of intermediate annealing, two to three times of acid and alkali washing process, straightening process. Under the condition of high temperature heating, the diameter of the wire can be controlled by hole die. The straight wire processing is difficult, the surface precision is poor, the hydrogen and oxygen absorption is serious, and the weight of single plate is low, which cannot meet the requirements of high precision titanium. Acid base cleaning surface has a great pollution, can only pickling the surface of titanium, and can not produce bright titanium. The straightening process will make the titanium surface of the formation of difficult to eliminate the straightening line, the titanium surface damage is more serious.

Titanium alloy pipes are processed by acid and alkali process. The straightening machine is used for titanium material straightening. This process is complicated, low production efficiency, low yield, resulting in a large amount of energy waste.
