Titanium is generally used in applications that require high temperature and high pressure service but are lighter in weight. Some good examples are components in the aerospace industry (airframe frames) and state-of-the-art equipment in the military. Given its excellent corrosion resistance in marine and chloride applications, titanium flanges are also popular as offshore drilling components and heat exchanger components. When you need a metal with good overall formability and workability, please choose titanium. It has the capability of hot or cold forming while maintaining its excellent mechanical properties. For transportation to your work site, it is good to know that titanium is much lighter than regular steel (about 40-45% lighter). Although not as light as aluminum, our titanium flanges and fittings are easier to handle during welding and installation.
