Pure indium wire refers to a filament made of pure indium. Indium is a rare metal with the following characteristics:

Low melting point: Indium has a relatively low melting point (about 156.6°C), which allows it to remain in a solid state even in low temperature environments.
Ductility and plasticity: Pure indium has good ductility and plasticity, and can be made into filaments or thin sheets, which are suitable for the manufacture of some special shapes.
Conductivity: Indium has good conductivity and can be used in some applications that require conductivity.

Application areas:
Temperature sensors: Pure indium wire is often used to manufacture temperature sensors. Due to its low melting point, it can be used to measure the temperature in low temperature environments.
Vacuum packaging: Indium wire can be used in the field of vacuum packaging, such as in the packaging of vacuum tubes.

Electronic components: Due to the special properties of indium, pure indium wire may also be used in the manufacture of some special electronic components.

Preparation and processing: Pure indium wire is usually prepared by smelting, wire drawing and other processes to ensure its purity and uniformity.
