Stuart:

You are correct. I think it was 1% copper, but it MAY have been much less
than 1%. I certainly never did any metallurgical analysis of the stuff. In the
days I used it, iron-plated tips were rare, if extant at all, and a plain
copper tip would last MUCH longer, when using this Ersin product. Made in
Cornwall, as I recall. It was half-again as expensive as generic "plain" 60/40
rosin core" such as Kester's. GOOD stuff.

I do NOT know if Ersin is still in the business, but I would certainly both
assume AND hope so!

Yes, their "multicore" had SEVEN holes down the length of even the 1 mm dia.
solder-wire! With "thinner walls", it took less heat to melt and for the
rosin core to "spill out" more readily all over the joint where it could do its
job.

I always thought it was curious that the English could produce such a super
product, but the "next-nearest" U.S. product was just-noticeably inferior
(though usually "good enough for church").

Yes Ersin is still making solder not sure of Savbit though. Try DigiKey.

Ersin solders is the only solder that will not cause an asthma attack for
me.

Used to work for a Litton division (medical X-Ray) and Kester solder was the
standard issue as it was a Litton division also. Had to "explain" why I was
buying Ersin solder instead of Kester.

They are still around, as Multicore Solders. They are now owned by Loctite,
who are owned by Henkel.

it is, i would say, common here.
my favourite mail order supplyer only carries sn60pbcu2.
i guess he thinks there is no need for copperless solder as you can also
use it
with iron coated tips (he sells mostly iron coated..).


it contains 2 percent copper as you say.
i used it in the past but noted not much difference in soldering.
currently i use mostly some copper free..
with iron coated tip there is no difference (for me).

but i know that standard solder can eat a copper area of several cubic
millimeters per afternoon.
i think if you have to use a copper tip it is worth a try but if you can
get a coated one do it.

i just had a look at another supplier (germany/austria) and they also sell
ONLY 2% copper solder.
even the new special halogene free and the Pb free solders have the copper
in it.
Only the silver solder (no not the type for hard soldering but electronics
solder with higher conductivity)
has silver instead of the copper.

main company here is STANNOL. also EDSYN is sold.

shouldn't be any problem to get copper containing solder in the future.
