Titanium screws are the same as ordinary stainless steel screws, iron screws, copper screws, but the raw materials used are different, titanium screws use titanium materials, titanium metal materials are generally divided into pure titanium and titanium alloy two materials, titanium metal elements have low density, performance strength is much better than other metal materials, And because the titanium metal element is currently mined less than the general metal element, the titanium screw raw materials on the market are also more expensive, and the general screw manufacturers have few titanium screws in stock. However, titanium screws produced by titanium metal elements are much more beautiful than screws of other metal elements, it seems to be handicrafts, and it is the most used screw raw materials in some high-end bicycles, automobiles, high-speed rail, rail and other industries.
Production of titanium screws
At present, the domestic and foreign production of titanium and titanium alloy wire mainly uses drawing, grinding, annealing, acid and alkali washing, cutting, straightening and other processes, in the entire production process requires 20 drawing pass, three to four intermediate grinding, ten intermediate annealing, two to three acid and alkali washing process, straightening process. Titanium screws, in the case of high temperature heating through the hole mold to control the diameter of the wire, straight wire processing is difficult, poor surface accuracy, serious hydrogen and oxygen absorption, single disc weight is low, can not meet the requirements of high-precision titanium; Acid and alkali cleaning surface has a great pollution, titanium screws, can only pickling the surface of titanium, and can not produce bright titanium. The straightening process will make the surface of titanium material form a straightening grain that is difficult to eliminate, so that the surface damage of titanium material is more serious

Titanium screws have excellent corrosion resistance
The passivity of titanium depends on the existence of oxide film, its corrosion resistance in the oxidizing medium is much better than in the reducing medium, and high rate corrosion can occur in the reducing medium. Titanium is not corroded in some corrosive media, such as seawater, wet chlorine, chlorite and hypochlorite solutions, nitric acid, chromic acid, metal chlorides, sulfides and organic acids. However, in the medium that reacts with titanium to produce hydrogen titanium usually has a high corrosion rate. However, if a small amount of oxidizing agent is added to the acid, the titanium will form a passivation film. Therefore, in the mixture of sulfuric acid - nitric acid or hydrochloric acid - nitric acid, and even in hydrochloric acid containing free chlorine, titanium is corrosion resistant. Titanium's protective oxide film is often formed when the metal hits water, even in small amounts or in the presence of water vapor. If titanium is exposed to a strong oxidizing environment in the complete absence of water, rapid oxidation can occur and produce a violent, often spontaneous combustion reaction. Such behavior occurs when titanium reacts with fuming nitric acid containing excess nitrogen oxide and when titanium reacts with dry chlorine. However, to prevent the occurrence of such reactions, a certain amount of water must be available.
