Indium Wire

Aster offers Indium Solder Wire with diameters ranging from 0.1mm to 6mm, typically boasting purities of 99.995% and 99.999%. Additionally, we specialize in crafting various Indium Alloy wires such as Indium Lead Alloy Wire, Indium Bismuth Alloy Wire, and Indium Tin Alloy Wire, among others. Introducing additional elements alters properties like melting point, hardness, and malleability. We tailor Indium Wire and Indium Alloy Wire to your specifications. Each order is accompanied by a Certificate of Conformity and a Quality Analysis Certificate.

Product Details

1. Low Melting Point: Indium solder wire has a relatively low melting point compared to traditional solders, making it ideal for delicate components that cannot withstand high temperatures.
2. Excellent Wettability: It can wet many surfaces that other solders cannot, including glass, ceramics, and certain metals.
3. High Thermal Conductivity: Indium’s excellent thermal conductivity is beneficial for applications requiring efficient heat dissipation.
4. Electrical Conductivity: It provides good electrical conductivity, making it suitable for electronic applications.
5. Ductility and Malleability: Indium solder is known for its softness and flexibility, which allows it to form robust seals without becoming brittle.

The minimum diameter for Indium Wire is 0.1mm, while the maximum is 6mm. Our tolerance for diameter is ±0.01mm. Before you send inquiry to us, please tell us the diameter and length or the weight you need. Should you have specific requirements, feel free to email our team for further discussion.

• Channel sealing, hand sealing, Indium is soft enough to fill the gap between the two metal surfaces of the mating, forming a complete seal.
• Ultra-low temperature sealing materials, when temperature -150°C , Indium retains ductility and malleable property.
• Welding or fusion.
• High-end device cooling.

1. Soldering and Brazing: Due to its low melting point and excellent wetting properties, indium wire is widely used in soldering and brazing applications. It is especially useful in electronics assembly and semiconductor manufacturing where delicate components require precise bonding​.
2. Sealing and Hermetic Packaging: Indium wire seal can create hermetic seals in vacuum and gas-tight enclosures. It is commonly used in the aerospace, automotive, and electronics industries to protect sensors, connectors, and optical devices from environmental contaminants​.
3. Thermal Interface Materials (TIMs): Indium wire is an effective thermal interface material, facilitating efficient heat transfer between components. It is used in CPUs, power electronics, and LED lighting systems to prevent overheating by dissipating heat.
4. Thin-Film Deposition: Indium wire serves as a source material in thin-film deposition techniques like thermal evaporation and sputtering. These processes are used to produce indium-based thin films for electronics, optics, and photovoltaic applications​.
5. Semiconductor Industry: Indium solder wire is widely used in the semiconductor industry for attaching components and ensuring reliable electrical connections. It is particularly useful in sealing infrared detectors and other heat-sensitive devices due to its low melting point and high conductivity.
6. Medical Devices: Precision soldering for medical devices often uses indium solder wire due to its reliability and quality, ensuring long-lasting and safe medical equipment.

Packing: Indium wire is packaged with wire spools, then vacuum bag in plastic container, 5meter/ roll or 250g/roll.

Transportation: By Fedex, DHL, UPS with door to door delivery, By Air

Storage: For optimal storage and to reduce surface oxidation, it’s essential to securely seal the indium wire in its original container. Maintain a relative humidity of 55% or lower and a temperature below 22°C. Alternatively, indium wire can be stored in an inert atmosphere, such as a nitrogen drying oven.

Our engineers boast extensive service expertise and offer comprehensive technical assistance to customers. They possess a profound understanding of indium wires and are well-versed in the applications of related materials within the electronics and semiconductor sectors.
