The more common lead-free solder systems have a higher melting point, e.g. a 30 °C typical difference for tin-silver-copper alloys, but wave soldering temperatures are approximately the same at ~255 °C; [47] however at this temperature most typical lead-free solders have longer wetting times than eutectic Pb/Sn 37:63 solder.

Lead-based house paint banned by the Consumer Product Safety Commission [9] 1986 Amendments to the Safe Drinking Water Act require new drinking-water waterpipes, solder, and flux to be "lead-free"; however, this is defined as less than 8% lead in pipes, and 0.2% in solder and flux. [10]
EPA illustration of lead sources in residential buildings Infographic about lead in drinking water. The Lead and Copper Rule (LCR) is a United States federal regulation that limits the concentration of lead and copper allowed in public drinking water at the consumer's tap, as well as limiting the permissible amount of pipe corrosion occurring due to the water itself.

Traditionally, lead has been added to slow down whisker growth in tin-based solders. Following the Restriction of Hazardous Substances Directive (RoHS), the European Union banned the use of lead in most consumer electronic products from 2006 due to health problems associated with lead and the "high-tech trash" problem, leading to a re-focusing ...

In those countries that have banned lead in solder for food and drink cans and have banned leaded gasoline additives, blood lead levels have fallen sharply since the mid-1980s. [294] The levels found today in most people are orders of magnitude greater than those of pre-industrial society. [81]

Early cans were often soldered with neurotoxic high-lead solders. High-lead solders were banned in the 1990s in the United States, [3] but smaller amounts of lead were still often present in both the solder used to seal cans and in the mostly-tin linings. Cans are highly recyclable and around 65% of steel cans are recycled. [4]
