    Default solder

    i have a full spool of solder thats been in the garage for i dont know how long.

    it is dutch boy and has the following markings:

    Sn 95% Sb 5% also says ASTM B-32.

    i also have a half spool of one that is oatey silver lead free solder but has no other markings.

    Just make sure that any solder that you do use doesn't say Pb on it which means lead.

    The solder you're using is a combination of 95% tin and 5% antimony solders also bearing silver exist however the SB SN mix is the most common.

    Default 95/5

    It is actually the other way around. Silver bearing solder is the most common. 95/5 is also available, but is not used as much as the regular stuff because it is less tolerant as far as heat is concerned.
