Soldering copper tube - product question

Has anyone used wire solder labeled: FRY A Cookson Group Co, Made in USA, 95% tin/5% antimony? I have a 1 lb roll - not sure if all solder is the same, i.e. solder for plumbing vs. solder for electronics. I'm trying to determine if my Fry/Cookson roll is useable for a plumbing project. I have not found my product on their website and, they mention both electronics and plumbing uses for their various solder products.

What you have is common "lead free" solder. Not the best in my opinion for use in electronics but fine for use in soldering copper piping. You need to get some paste flux made for lead-free solder. Oatey number 95 is a brand I have used with complete success. You will need to heat the joint hotter with this solder than you did with the old 50-50 tin/lead solder.
