Indium-based solder wire for specialized joining
Jufeng Solder supplies multiple indium-containing wire alloys for processes that require lower joining temperature, compliant solder joints, specialized alloy behavior or carefully controlled heat input.
Broad Alloy Selection
Choose from pure indium, indium-silver, tin-indium, tin-bismuth-indium and multi-element alloy systems.
Low-Temperature Options
Multiple alloys support assembly below conventional SAC soldering temperatures.
Solid & Flux-Cored Wire
Select separate flux control or convenient built-in flux according to alloy and diameter.
Soft Joint Behavior
Indium-rich alloys can provide compliant joints for selected thermal mismatch applications.
Precision Applications
Suitable options are available for sensors, optical modules, die attach and delicate electronics.
Custom Manufacturing
Diameter, packaging and flux form can be discussed for evaluation and production orders.
Series Overview
Use the table below for initial product selection, then confirm the final alloy, diameter, flux form and process profile before production.
How to Select
Start with the required melting range and joint behavior, then evaluate substrate compatibility, service temperature, flux chemistry, wire diameter and reliability targets.
