This is great lead free solder that contains 4% silver. It flows well, but requires a higher quality, hotter iron, because of the higher melting temperature. The older, leaded solder, had a lower melting temperature.
This version has a slightly smaller diameter – .025″ (0.40-0.50 is typical). However, a good fix for this is to double up the length and twist it together! Therefore, buy twice as much as you would normally use.
