The Materials You Need When You Need Them

Tantalum Refractory Metals

Tantalum is famous for its resistance to corrosion by acids; in fact, below 150˚C, tantalum is almost completely immune to corrosion by aqua regia. Due to its resistance to attack by body fluids, tantalum provides an excellent material for medical devices. Another major use of Tantalum is for electronic components and due to its absorption properties, it is an excellent getter of residual gasses in evacuation tubes.
