Bar Solder
Indium Corporation manufactures high quality, very low oxide content, extruded bar solder for wave, fountain, and dip soldering applications. We use only "conflict-free" grade A tin, per ASTM B32. Our bar solder alloy composition and purity meets, or exceeds, the requirements of ASTM B32, IPC J-STD-006, and JIS Z 3282, as well as all other similar industry and customer specifications.
