More Coffee:
I understand your comments and I thing 3-4% silver and the balance of Tin should be Silver bearing Solder.
The plumbing stuff is usually a Tin/Antimony solder.
I was aware of the copper designations and it makes sense to use Copper K for high pressure.
The company in question says this stuff is "Silver solder" and I say they need to provide more info on the RETAIL packaging, particularly Alloy and/or solidus and liqudus points.
So, far there seems to be no one that really agrees with me that:
1. Important info is missing from the retail package. (alloy and/or solidus/liquidus points)
2. A google image search of solder brings up spools with the alloy on them if you can get to a pic that you can read. Sometimes it's just 50/50 or 63/37 and not the elements.
So,
1b. Do you agree with me that alloy should be on the package and why?
2b. Do you agree that not providing it visibly on the retail package is like buying grape soda as "High fructose corn syrup manufactured by the ABC company". Flavor would be an importany part of the purchasing decision just as alloy type is?
3b. 3-4% and the balance tin is Silver bearing Solder, not "Silver Solder"
The other real question is when you hear "Silver solder", do you think "silver brazing rod" or not?
