Will this bond to aluminum lithium battery tabs?

It is ok to use this lead-free solder wire for your product,

Is this lead free solder as good as lead solder?

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,
