## Questions & Answers

**Q: How many feet or centimeters are on a spool, please?**
A: No idea I never Measure it.

**Q: Will this bond to aluminum lithium battery tabs?**
A: It is ok to use this lead-free solder wire for your product,

**Q: Is this lead free solder as good as lead solder?**
A: Dear Customer,

Thank you inquiry our Lead Free Solder Wire for electrical soldering,

I think the Lead free solder is better than Lead Solder wire, because it is good for environmental,

The melting temperature for Lead-free solder is a little higher than the Leaded solder, but I think it is not a problem for soldering, 
The flowability of lead solder is a little better, but it is not a case if you are good in soldering, 

All factory were using Lead Free solder for many years, 

I hope my answer helpful for you,

Regards,

Great wire...very thin... great for electronics, no acid core

### ⭐⭐⭐⭐⭐ Perfect for the fine soldering projects as to solder on header pins on the board
*by J***N on December 16, 2023*

I use this to solder all my projects I have a solder gun at 900° and it works instantly nice flow fills the holes leaves a nice clean solder and it's thin enough that you don't accidentally solder two pins together perfect for slaughtering on header pins to a circuit board even detailed repair my advice is make sure you use tinner on your solder gun and trust me you won't have any problems
