Titanium Wire GR7

In addition, titanium wire is also used in sporting goods, eyeglasses, earrings, headgear and other consumer goods, as well as seawater and salt water heat exchangers, condensers and paper bleaching system engineering and other industrial areas. The application of titanium wire not only reflects its excellent performance, but also demonstrates its importance in modern industrial and medical technology.

Titanium wire density is small, high specific strength, corrosion resistance titanium is a very active metal, its equilibrium potential is very low, in the medium of thermodynamic corrosion tendency is large. But in fact titanium is very stable in many media, such as titanium in the oxidizing, neutral and weakly reducing medium is corrosion resistant. This is because titanium and oxygen have a great affinity, in the air or oxygen-containing media, titanium surface to generate a layer of dense, strong adhesion, inert oxidized film, protecting the titanium substrate from corrosion. Even due to mechanical wear and tear will soon self-heal or regenerate. This shows that titanium is a metal with a strong passivation tendency. Medium temperature below 315 ℃ titanium oxide film always maintain this characteristic. In order to improve the corrosion resistance of titanium, surface treatment techniques such as oxidation, electroplating, plasma spraying, ion nitriding, ion implantation and laser treatment have been investigated, which play an enhanced protective role on the oxide film of titanium, and the desired corrosion resistance effect has been obtained. A series of corrosion-resistant titanium alloys such as titanium-molybdenum, titanium-palladium, titanium-molybdenum-nickel, etc. have been developed in response to the need for metal materials in the production of sulphuric acid, hydrochloric acid, methylamine solution, high-temperature wet chlorine gas and high-temperature chlorides. Titanium castings using titanium-32 molybdenum alloy, often occurring crevice corrosion or pitting corrosion of the environment using titanium-0.3 molybdenum-0.8 nickel alloy or titanium equipment for local use of titanium-0.2 palladium alloy, have obtained very good results.
