solder

[wgr]

i have a bar of solder, it says swipe solder on it . anyone know what it is?

[just.don]

that means if you mail it to me, on your dime, i will have swiped it from you.

PM for my address

in radiator repair, once one has cleaned,fluxed and heated the questionable area of the radiator, the solder bar is swiped (think spread/smeared/wiped) across that area.

what is the lead tin content

[duck hollow pete]

wiping solder for high voltage underground elec. lead joints is 40/60 sn/pb

[dieguy59]

Is it the standard to list the tin first ?

you are right sorry
:oops:

[dieguy59]

Wait, it was a serious question. Haha

[OneSkinnyMass]

I would like to know also, is there a standard way to state an alloy? like most % to fewest % or alphabetically?

Standard for tin/lead solder is tin%/lead% as stated by duck hollow pete.

[floydboy]

Do radiator shops generate a lot of solder??? Is it a good place to go for tin? I hear of people going there for used solder. Seems to me if it's that expensive they would reuse it also.

I'm guessing they need the solder in wire or bar form. I'm not sure why they don't sell it to a salvage outfit. If they spend time trying to reclaim it themselves, that is time they aren't repairing radiators.

I was thinking lead solder mixer were stated as lead,l then tin. Like 60/40 - 60 lead, 40 tin. Just my .02. enjoy Mike

Definitely %tin/%lead, as in 63/37, the mix with perfect eutectic properties. Just google it.

+1 I have several boxes of wire solder rolls that have never been opened. They have printed on the outside 40%Sn/60%Pb. I have never seen it any other way except in posts here on this board.

I have a good supply of 50/50, but I don't know which is the lead and which is the tin.

If you can find a shop that does farm equipment radiators, chances are they use solder.
Around here, all of the shops only deal with plastic tanks.
I have found a lot of new and partial rolls and bars at the recycler here.
Depending on who is working at the time, I buy it at 40 to 50 cents,,, same as lead.

Mike- This guy is asking a legitimate question, and your response is of no help... But it WAS funny. Har-Har-Har.

Sorry, Guy, too many years answering questions like tech-support -- informative, truthful, and utterly useless. :)
I did learn something from this thread, so I thank all the serious participants. I've spent my entire life not knowing that the tin content was the first number in the solder description. I always assumed it was the lead (in lead bearing solder), and then tin in the lead-free stuff. Now I know better.
At least with the 50/50 I couldn't screw anything up...

Eutectic solder is indeed 63/37 ( 63%Sn/37%Pb) !

The 40/60 solder can be used to build up a joint because it is 40% tin and 60% lead and has a long slushy phase.
The 63/37 solder is eutectic and cannot be used to build up because when it melts its totally liquid. Great for electrical work because of its superior flowing ability and low temperature melting point. The 63/37 is for a fact 63% tin.

It has been said my many that the way alloy components are listed is by the most expensive first. Eg. 2-6-92 is tin/antimony/lead. Although now days antimony price is closing in on tin but the mold has already been set.

Mike- Seriously, I really thought you were making a joke. Sorry I misunderstood. It's not a sin to be naive about something, we all ask questions here and learn from each other. I've been asking a lot of them since I got back into casting and reloading after a 20 yr. hiatus. Gotta go now and cut some trees down for my wifes garden. Good casting to ya...
