Products Description
Tantalum mainly exists in tantalite and coexists with niobium. Tantalum has a moderate hardness and is highly ductile, allowing it to be drawn into thin wire foil. Its coefficient of thermal expansion is very small. Tantalum has excellent chemical properties and extremely high corrosion resistance. It does not react with hydrochloric acid, concentrated nitric acid, or aqua regia under both cold and hot conditions. It can be used to manufacture evaporative vessels, as well as electrodes, rectifiers, and electrolytic capacitors for electronic tubes. Used in medical practice to make thin sheets or threads to repair damaged tissues. Although tantalum has strong corrosion resistance, its corrosion resistance is due to the formation of a stable tantalum pentoxide (Ta2O5) protective film on the surface.

Products Application
The characteristics of tantalum make its application fields very broad. In equipment for producing various inorganic acids, tantalum can be used as a substitute for stainless steel, and its lifespan can be increased by dozens of times compared to stainless steel. In addition, in industries such as chemical, electronic, and electrical industries, tantalum can replace tasks previously undertaken by the precious metal platinum, greatly reducing the required costs. Tantalum is manufactured into capacitors for military equipment.

Products Advantages
High melting point
Tantalum metal is a high melting point metal with a melting point of around 3017 ℃, making it one of the metals with the highest melting point except for tungsten. This high melting point means that tantalum metal can withstand stress and thermal expansion in high-temperature environments, making it perform well at high temperatures.
High strength
Metal tantalum has high strength and toughness, which can maintain shape and strength under high stress. This makes it an ideal choice in the aerospace industry.
Corrosion resistance
Metal tantalum has good chemical stability and corrosion resistance, which can resist most corrosive media. This characteristic makes it the preferred material in fields such as chemical, medical, and food.
Superconductivity
Metal tantalum has superconductivity and can achieve zero resistance transmission current at extremely low temperatures, which makes it have broad application prospects in fields such as medical imaging, nuclear magnetic resonance, particle accelerators, and so on.
Good processability
Metal tantalum has good machinability and is easy to machine and form, making it suitable for manufacturing complex shapes and high-precision parts. At the same time, metal tantalum can also be welded, brazed, and bonded, providing excellent weldability.
Production Process
Tantalum cannot be processed using ordinary methods of processing general metals. The initial process is usually forging and heat treatment, using two methods: hammering and stamping to produce flat billets or circular small and medium-sized billets.
To manufacture rod products, the material is first forged or extruded into a moderate size in the middle, with a representative cross-sectional yield of 70% -90%, and then subjected to annealing heat treatment. When processing again, forging, rolling, extrusion, or drawing processes are usually used. The wire is processed using a regular wire drawing machine. Due to the softness of tantalum materials, they are prone to scratches, resulting in significant surface issues during drawing. Manufacturers should pay special attention to surface condition and lubrication.
