Learn what solder is from expert Jeff Koskulics in this Howcast video. Solder is a material that is used to join soft metals, such as copper, gold, and silver. In electronics weâre mostly concerned with copper. Most commonly weâre using eutectic solder, which is a combination of tin and lead. This is eutectic solder, this is 63 percent tin, 37 percent lead, and this is made with a formulation that has a very minimum melting point for this combination of metals. The melting point is somewhere 360 degrees Fahrenheit.
S oldering; very simply put is 'gluing' two pieces of metal together by applying heat and melting a third metal or alloy into the joint. This third metal or 'solder' must melt at a lower temperature than the metal being soldered and be able to adhere to the surfaces being joined. N ot all metals can be soldered easily. Copper, Brass, Bronze, Nickel and Tin are all metals that can be soldered at soldering iron and propane torch temperatures (400-800f) and use solders and fluxes that are readily available. Aluminum and stainless steel do not solder easily.
