Solder is an alloys usually made up of tin or lead used to join metallic parts. It is symbolized by two numbers which represents the percentage of each metal in a mixture. The first number refers to the percentage of tin and second to the percentage of lead. It usually melts at a temperature of about 200°C. Read more about soldering techniques.
Types of solder
· 60/40 solder– its composition is 60% tin and 40% lead. It melts at 374oF. It forms high, rounded, beaded seams. Because of its low relatively melting point this type of solder is easy to rework to maintain a smooth finish.
· 50/50 solder– its composition is 50% tin and 50% lead. Its melting point is 421oF. This type of solder produces a much flatter bead than 60/40. Because of its high melting point this type of solder is often used on the back of stained glasses, to protect it from melting when soldering the front.
· 63/37 solder– its composition is 63% tin and 37% lead. This type of solder is an excellent solder to bead up the outside rim of copper foiled pieces. It is often referred as decorated or quick set solder.
· Lead free solder– This type of solder performs similar to 50/50 solder. Lead free solder is a most expensive solder, but when constructing pieces that will contact food or that are handled frequently, this type of solder is different.
