Specification of Indium

Symbol: In
Atomic number: 49
Atomic weight: 114.818
Element category: post-transition metal
Indium is chemically very similar to gallium, and both of them are able to wet glass. It is used in low-melting fusible alloys such as solders, soft metal high vacuum seals and coating for bearings. It also can be used to form transparent conductive coatings of indium tin oxide (ITO) on glass.

Advanced Refractory Metals (ARM) now can provide indium metal products including:
Shapes: ingot, foil, sheet, strip, wire, custom shapes;
Purity: ≥4N5

Indium Product Description

Indium is a soft, silvery-white metal known for its low melting point (156.6?°C), excellent malleability, and ability to form airtight seals. Available in forms like ingots, wire, foil, and powder, ARM’s high-purity indium is widely used in the electronics and semiconductor industries. Its non-reactive nature and strong wetting properties make it perfect for soldering, bonding, and heat transfer applications.

Applications of Indium

• Semiconductors & Electronics: Used in LCD displays, touchscreens, and solders.

• Thermal Interfaces: Ideal for heat sinks and thermal pads in high-performance electronics.

• Sealing Applications: Forms reliable seals in vacuum and cryogenic systems.

• Alloys: Added to improve the strength and corrosion resistance of other metals.

• Nuclear Industry: Acts as a neutron absorber in certain reactor designs.
