Lead-free solder is used for computer repairs, electric appliances, printed circuit boards, and phone and cable applications. This solder has a flux core, which eliminates the need for additional flux. It does not produce toxic fumes when heated.

Leaded solders have a lower melting point with better wettability than lead-free solders. They are used in the repair of electric appliances, computers, printed circuit boards, and phone and cable applications. Leaded solders should be used only in areas with proper ventilation systems.

These lead-free solders meet NSF standards for applications involving potable water. Typical uses include plumbing, refrigeration, and cooling systems. This lead-free solder does not produce toxic fumes when heated.

Silver-bearing solder provides better capillary action than solders without silver, improving flow into tight spaces without gravity or other external forces. These solders are often used on joints in HVAC equipment and other areas subject to frequent vibration. They also eliminate the oxide scale that results from brazing and do not produce toxic fumes when heated.

Lead-free solder is often used for tin repairs, sheet metal, auto radiators, metal gutters, and non-electrical applications. This solder does not produce toxic fumes when heated and is not for use in plumbing or other applications involving potable water.

Leaded solders have a lower melting point with better wettability than lead-free solders and do not require fluxes or cleaning agents, which improves conductivity between metals. These solders are used for tin repairs, sheet metal, auto radiators, metal gutters, and non-electrical applications. These leaded solders are not for use in plumbing or other applications involving potable water and should be used only in areas with proper ventilation systems.
