I thought the sort of solder for electrical work that contains a small
amount of silver also contains the usual amount of lead?

My mistake. It seems all lead-free is silver, but not all silver is lead-
free.

Besides, it's the first I've heard of the lead in solder being a health
hazard under normal use. The flux, yes.

Hasn't lead got to be a dust or actually incinerated before it's a hazard
to breathe?

Not sure. I've always been tought to try not to breathe the fumes from the
standard 60/40 stuff. Would be interesting to hear if they actually are
harmful.

For occasional DIY I seriously doubt there is any real health hazard. H&S
regulations require some form of extraction for regular use. But I'd
always thought this was mainly for the flux fumes which are carcinogenic.

I'm not sure what the lead free stuff that's now required on potable water
pipes consists of - or that it's suitable for electronics.

'Real' silver solder is a form of brazing and requires a much greater
heat.

True, but there are also valid resons for it's use. My solder contains

It contains a little silver as well as the usual amount of lead,
doesn't it?

Anyway, the fumes are from flux burning up. I doubt your iron is hot
enough to vaporise lead. Which would, indeed, make a bit of a mess
of your lungs :-)

The stuff I use is lead-free. It was on special offer so hardly more
expensive than 60/40. It contains some small amount of silver (10%). I
quite like using it - Lead free has a lower melting point, so easier to
do large joints without a high power iron.

Ah, well. If I've heard wrong, it's at least the same.

Although lead free is common for mechanical soldering - like copper tube -
I understood the need for it was giving the electronics industry real
headaches. ;-)
