Product Overview
Solid Core Wire
Most of our alloys are available as solid core, no-flux center. The most popular diameters are between 0.010”–0.254mm and 0.062”–1.52mm; however, SnAg and AuSn alloys are available in diameters less than 0.010”–0.254mm.
Product Availability
Solid core wire is available in pure indium and indium-based alloys, bismuth-based alloys, SAC alloys, Pb-based alloys (including high Pb), 80Au/20Sn, and Pb-free alloys.
Flux-Cored Wire
Flux-cored wire is generally used for manual soldering or rework and is increasingly used in robotic soldering applications. A variety of flux cores are available including no-clean, water-soluble, and halogen-free.
Typical Alloys for Flux-Cored Wire
These include SAC alloys; other Pb-free alloys such as SnAg, SnCu, and SnSb; Pb-containing alloys including SnPb and SnPbAg; and high Pb-based alloys.
