Do you know titanium? The total amount of titanium resources is the world's top, a total of 965 million tons, accounting for 38.85% of the world's proven reserves, mainly concentrated in Sichuan, Yunnan, Guangdong, Guangxi and Hainan, etc.. The earth's surface ten kilometers thick strata, containing titanium up to six thousandths, 61 times more than copper, the content of the earth's crust ranked tenth, just grab a handful of clay from the ground, which contains a few thousandths of titanium.
Titanium heat resistance is very good, the melting point of up to 1668 degrees Celsius, at room temperature, titanium can lie unharmed in a variety of strong acid and alkali solution, it will be sunk in seawater for five years, and then take up to see, no rust at all, or still bright and shiny. Titanium has plasticity, high purity titanium elongation of up to 50-60%, section shrinkage of up to 70-80%, the presence of impurities in titanium, the mechanical properties of its great impact, titanium as a structural material with good mechanical properties, is through strict control of the appropriate content of impurities and the addition of alloying elements to achieve.
From the discovery of titanium to the production of pure products, it has been more than 100 years, in the 1940s, titanium was really used to recognize its original true nature.
