Product Overview
Indium solder wire is an alloy that has a significant amount of indium. Indium itself is a soft, silvery-white metal recognized for its low melting point. In contrast to conventional tin-lead solders that require high temperatures to melt, indium alloys can flow at temperatures as low as 157°C (314°F), which is considerably lower than other metals. This property makes them ideal for connecting heat-sensitive components, such as medical devices, optical systems, and cryogenic applications. This type of wire enables precise application, making it appropriate for both manual and automated soldering processes.
Features:
- Low Melting Point: Indium solder boasts a melting point as low as 156.6 °C, which is considerably lower than typical tin-based solders, thereby safeguarding sensitive components.
- High Ductility and Malleability: The inherent softness of indium enables it to deform and flex, effectively absorbing stress from mismatched coefficients of thermal expansion (CTE) between various materials. This characteristic helps prevent joint fatigue and failure, particularly in environments subject to thermal cycling.
- Excellent Thermal and Electrical Conductivity: Indium serves as a proficient conductor of both heat and electricity, rendering it an ideal choice for thermal management and ensuring dependable electrical connections.
- Vacuum and Cryogenic Compatibility: Thanks to its low vapor pressure and capacity to maintain malleability at extremely low temperatures, indium is an optimal material for hermetic seals in vacuum and cryogenic applications.
- Lead-Free and RoHS Compliant: Our indium solder wire is a safe and eco-friendly alternative that adheres to contemporary regulatory standards.
