A 0.8mm lead-free solder wire composed of 99.25% tin and 0.75% copper, ideal for use on micro electronics, fine wires and most other electrical and electronic soldering applications.
A. Hi Mike, thanks for your question. Yes, the solder is flux cored.

Excellent sampler for switching to lead-free

I'm a hobbyist using a thermostatic iron designed for 60/40 solder, sometimes making toys for a Small Person. This is a great price for trying a new alloy.
With a dirty iron tip, while leaded solder just about worked this was unusable. Tip was long overdue a good clean, now this 0.75%Cu flows just fine.
0.8mm is a bit thick for my liking, but 0604 SMD is still possible.
Haven't tried it with a beginner. Can't comment on long term reliability.
