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.
Solder is the small piece of alloyed metal that is melted in order to fuse two other pieces of metal together. The place where the metals are fused by solder is called a joint. The solder metal is of a lower melting temperature than the two pieces itâs fusing. Solder comes in three types: hard, medium, and easy. All three types have different melting temperatures. Hard solder melts at a high temperature, medium melts at a lower temperature, easy melts at an even lower temperature.
