Indium Bar Solder

Features and Benefits

Indium Corporation 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.

Bar solder chips are also available and are commonly used to fill smaller solder pots or to quicken the melting of solder in a new solder pot. The greater surface area of the chips allows for better heat transfer between the solder pot and the metal.

Alloys for dip tinning and other applications: 50Sn/50Pb, 40Sn/60Pb, 30Sn/70Pb, 10Sn/90Pb, 5Sn/95Pb, 96.5Sn/3.5Ag, 95Sn/5Sb, SAC105, and others upon request
