Indium Corporation is quickly becoming known as one of the highest qualities, 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.
