Tin Content

[Faret]

Anybody know what the tin content is?

I would think near zero.

it might be 50-50 solder, but I am not that versed in tin.

My guess. Near Zero.
If you can bens it easilt its lead. if its solder it will resist and groan. Also will ring.

[runfiverun]

bars like that clack not tink.
they may even tack if they are 50-50 or higher.
i go by the how hard they are to bend method.

[Faret]

Does not tink but is harder than pure lead more like ww.

Bar ingots of solder are usually marked with the actual percentages of the metals in the alloy.
Common tin/lead solders are 50/50, 60/40, and 63/37 (eutectic). Then, there is 40/60 (40% tin/60% lead).

Solder specifically identified as 'plumber's solder' is usually expected to have two parts of lead to one part of tin, and is used primarily for making wiped joints.

From what I've been able to gather it seems that solder considered to be "plumbers solder" ranges from 1 part tin to three parts lead to a 50/50 mix.

I was thinking of the old plumbers lead that they used to seal cast iron pipe joints with .

[runfiverun]

probably 30% tin.
but could be up to 50% tin.
if you only have one lb throw it in 50 lbs of ww's and be happy. if it's more try it in 100 lbs.
you can always add a bit more.

Thanks for the replys. I have another bar in a different thread if anybody could help?

I would say zero. Oh, wait, I thought we were talking about the hole under the bar...
