Titanium foil material is mainly used for loudspeaker and speaker treble film, with titanium foil to do high fidelity, clear and bright sound. Titanium foil material can also be used in precision accessories, used for bone implantation, etc. Titanium, which looks like steel and has a silvery light, is a transition metal and has been considered a rare metal for some time. Titanium is not a rare metal. It makes up about 0.42 percent of the earth's crust by weight, 16 times as much as copper, nickel, lead, and zinc combined. It ranks seventh in the metal world, with more than 70 minerals containing titanium. Titanium has high strength, low density, high hardness, high melting point and strong corrosion resistance; High purity titanium has good plasticity, but becomes brittle and hard in the presence of impurities.
It is a silver-white transition metal characterized by light weight, high strength, metallic luster and resistance to wet chlorine corrosion. But titanium can not be used in dry chlorine gas, even if the temperature is below 0℃ dry chlorine gas, will also take place drastic chemical reaction, generate titanium tetrachloride, and then decompose to generate titanium dichloride, and even combustion. Only when the water content of chlorine is above 0.5% can titanium remain reliably stable in it. Titanium is considered a rare metal because it is dispersed in nature and difficult to extract. But it is relatively abundant, ranking tenth among all the elements. Titanium ores mainly include ilmenite and rutile, widely distributed in the Earth's crust and lithosphere. Titanium is also found in almost all living things, rocks, water and soil. The extraction of titanium from the main ore requires the use of the Crore or Hunter process. The more common compound of titanium is titanium dioxide, which is used to make white pigments. Other compounds include titanium tetrachloride (TiCl4) (used as a catalyst and as air cover for smoke screens) and titanium trichloride (TiCl3) (used as a catalyst for the production of polypropylene).
It has the characteristics of high specific strength, good corrosion resistance and high heat resistance and is widely used in various fields. Titanium is non-toxic, light, high strength and has excellent biocompatibility, is a very ideal metal material, its heat resistance, strength, plasticity, toughness, formability, weldability, corrosion resistance and biocompatibility are good. The use of ultra-thin high purity titanium foil belt: In addition to the industrial pure titanium manufacturing parts, a large number of titanium alloy is used. It is increasingly widely used in aviation, aerospace, chemical, shipbuilding, metallurgy, electronics, medical, petroleum, medicine, military and other industrial sectors to manufacture gas turbine components.
