Indium Corporation is quickly becoming known as one of the highest quality, full-line suppliers of flux-cored wire solder.

Indium Corporation uses only "conflict-free" and grade A (per ASTM B32) metals, as well as other high purity metals for its flux-cored wire. Our materials have been tested and certified to meet IPC J-STD-004B and other relevant industry specifications, including the legacy military specification QQ-S-571f.

CW-301 Wire Solder is cored with a high-reliability water-soluble flux that is compatible with Indium Corporation’s full line of Pb-free soldering materials. It provides excellent solder spread with minimal smoking and low odor. The fast wetting speed is beneficial in minimizing rework cycle time which is typically longer with Pb-free solders.
