CW-102 Non-Activated Rosin Flux-Cored Wire - Sn62/Pb36/Ag2, 0.025-inch, 1 lb Spool
Indium Flux-Cored Wire
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. Indium Corporation’s flux-cored wire is well known for its:
- Void-free
- Evenly layer winding
- Low oxide shiny appearance over time
- Non-offensive odor for the 800 series and 200 series fluxes
CW-102 Non-Activated Rosin Flux-Cored Wire
Non-Activated Flux-Cored Wire CW-102 is a type “R” flux to be used with legacy military contracts requiring a flux-cored wire meeting QQ-S-571F (or predecessor). CW-102 contains pure Grade WW gum rosin.

Shelf Life
Always store cored wire in a cool, dry environment. The main causes of degraded cored wire reflow performance are the buildup of a thick oxide layer on the surface of the wire, caused by prolonged exposure to higher than normal temperature and humidity conditions, or the buildup of lead carbonate on high-lead (>85%) alloy cored wire shipped or stored under very high-humidity conditions.
