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.
The melting temperature is when the solder starts to melt, and the flow point occurs when the solder is completely molten. The difference between these two temperatures, or spread, can be from 25Â°F to more than 100Â°F.oft soldering uses very low melting temperature solder alloys, usually of tin and lead, and is not commonly used in fine jewelry. Solder is a nonferrous (without iron) metal alloy, the major percentage of which is usually the same as the metal being joined: gold, silver, copper, or brass.
