Tantalum plate is widely used in national superconducting technology, capacitor shell, chemical industry, medical treatment, and other fields because of its high melting point, low vapor pressure, small expansion coefficient, good processing performance, good dielectric property, and excellent corrosion resistance. Tantalum alloy has high-temperature strength and excellent processing performance and can be used as structural materials for aerospace.

Heeger Materials supplies tantalum plates in a length of up to 3.2 meters and in a width of up to 800 millimeters.
