TITANIUM HAS A HIGH STRENGTH TO WEIGHT RATIO WHICH DICTATES MANY OF ITS MORE IMPORTANT APPLICATIONS IN THE AEROSPACE INDUSTRY.
Tantalum is corrosion resistant, due to a tenaciously adherent oxide film akin to the entire family of passive, reactive metals. The metal has gained acceptance for use in electronics, missile technology, the chemical industry and the medical field. Tantalum is immune to attack by many acids and salt solutions. It is, however, subject to hydrogen embrittlement in alkaline solutions. It is used to fabricate heat exchangers, reaction vessels, bayonet heaters, thermo wells, surgical implants and radiation shielding. Tantalum should not be used in air at temperatures above about 300°C because of severe oxidation.
