How much lead does solder dor electronics contain? I
thought only
solder for pipes contained lead?
The best alloy is 63/37 63%lead 37% tin. Common variety is 60/40.
The lead is not a hazard by inhalation though some of the fluxes can be.
It is a contact hazard over time as it can be transfered from the skin to
lips
and injested. Solution, wash hands after using.
Solder for pipes, by mandate has been below 5% lead for years, it
used to be mostly lead {90/10}.
>>It's true. The mercury was used to stiffen
the brims. Chronic hat
wearers
>>also had problems.
Lead is bad as it's water soluable if the PH is right. Mercury is nastier
as
it has a low boiling temperature and combines with Oxygen readily.
