Tantalum Tungsten Wire Description
Tantalum tungsten is a high strength metal alloy. It has a high melting point, tension resistance and corrosion resistance. SAM’s tantalum alloys are made using power metallurgy techniques by mixing tantalum powder with alloy elements and filling them into molds, compressing them at temperatures of up to 2000 bars, and then sintering them. Tantalum tungsten alloys are stronger than pure tantalum and are useful for corrosion and heat applications at temperatures of up to 1600 °C, making them an excellent material for wire.

Tantalum Tungsten Wire Application
1. Aerospace: Due to its extremely high melting point and excellent thermal stability, Tantalum Tungsten Wire is often used in the manufacture of high-temperature components in aerospace vehicles, such as rocket engine nozzles, combustion chambers, etc. These components operate under extremely high-temperature environments and require materials with excellent high-temperature resistance, which is exactly what is needed. These parts work in extremely high-temperature environments, requiring materials with excellent high-temperature resistance, and tantalum tungsten wires just to meet this demand.
2. In the field of nuclear industry: Tantalum Tungsten Wire has become a key material in nuclear reactors due to its strong radiation resistance and good thermal stability. It can be used to manufacture structural parts of reactors, heat exchangers and radiation shielding materials, etc. to ensure the safe and stable operation of nuclear facilities in a strong radiation environment.
3. In the field of electronics industry: Tantalum Tungsten Wire has good conductivity and high temperature resistance, which makes it an ideal material for electronic components. It can be used to manufacture electrodes, leads and connecting wires for high-temperature electronic devices, such as vacuum electron tubes and thermocouples for high-temperature furnaces.
4. Medical devices and surgical tools: Due to the good biocompatibility of Tantalum Tungsten Wire and its high hardness and wear resistance, it is often used in the manufacture of medical devices and surgical tools, such as surgical sutures and cutting tools. These tools need to withstand certain mechanical pressure and friction during the medical process, and tantalum tungsten wires can maintain stable performance and long service life.
5. High-temperature furnace and electric heating element: Tantalum Tungsten Wire is often used to manufacture heating elements and electric heating wires for high-temperature furnaces because of its high melting point and good electrical properties. It can work under high temperatures for a long time without melting or deformation, ensuring the stable operation and heating efficiency of the high-temperature furnace.
6. Special welding and joining technology: In some special welding and joining processes, it is necessary to use metal materials that can withstand high temperatures and good stability. Tantalum Tungsten Wires are indispensable for these processes due to their high-temperature stability and excellent electrical conductivity.
