Titanium rod is a kind of special metal, its density is small, weight is light, strength ratio is very high, and corrosion resistance is strong, it will not darken like sliver, at room temperature, it can keep itself silver tone all its life. The melting point of titanium is very high, which is commonly used in aerospace and military precision components. In the field of chemical reaction, strong corrosive agent "aqua" can gobble up silver, gold, and even the so-called "stainless"stainless steel, however, the "aqua" is helpless to the titanium, titanium is immersed in the "aqua" a few years, it still shines.
At room temperature, titanium is stable in the air, because titanium has low density, high intensity, its density is half of the steel and the strength is almost same with the steel. It has some excellent properties, such as high temperature low temperature - resistant, corrosion resistance. The strength of titanium alloy is higher than that of steel. Titanium is also call "space metal", in the -500℃ to -253℃, titanium can maintain high strength and mechanical properties. Since the 50's, the proportion of titanium in the aerospace industry is getting bigger and bigger, titanium alloy is the necessary material to make the rocket engine shell, the artificial satellite and the spacecraft.
Titanium plate has a unique use in medical scholars, titanium metal will not produce chemical reactions to contact with material. That is to say, because titanium has good corrosion resistance and high stability, which make it not affect the nature after long-term exposure with people, so it will not cause allergies, it is the only metal that will not have effect on the human plant nerve and taste. Titanium is also known as the "Pro biological metal."
