Titanium rods

Product Details------------------------------------------------ ------------------------------

one. Titanium rod overview　

Passive titanium rods and titanium alloy rods are new structural materials. Because titanium has high melting point, small specific gravity, high specific strength, good toughness, fatigue resistance, acid and alkali corrosion resistance, low thermal conductivity, high and low temperature resistance, Features such as low stress under the conditions of rapid cold and rapid heat. It is used in high-tech fields such as aviation and aerospace, and is continuously promoted to industries such as chemical, petroleum, electric power, desalination, construction, and daily necessities.
