ASAHI WC63B10E
ASAHI WC63B10E is a flux-cored solder wire with an Sn63Pb37 solder alloy. It is used where one wants solder that provides both solder metal and flux in a single wire. This makes the work more efficient during manual soldering, as the flux helps the solder flow and spread quickly over the workpiece.
The built-in CF-10 activated rosin flux is classified as ROH1, i.e., a no-clean flux. In practice, this means that residues are usually small, dry, and light yellow, and that cleaning after soldering is typically not required. This is particularly relevant when a simple process without additional cleaning steps is desired. The recommended soldering temperature is between 270 and 350 °C, and the soldering time is 1-3 seconds.
The wire is available in several diameters from 0.5 to 2.0 mm, so it can be adapted to both fine work and more general soldering tasks. Packaging is available in 0.25 kg, 0.50 kg, and 1.0 kg.
Typical applications
Used for general manual soldering where a leaded Sn63Pb37 solder wire with built-in flux is desired, and a process that normally does not require subsequent cleaning.
