The melting point of silver solder varies, depending on the chemical composition of the solder being used. Solder that is composed of 56 percent silver will have a melting point of 1,145 degrees Fahrenheit, while solder composed of 80 percent silver melts at 1,370 degrees Fahrenheit.
The melting point of silver solder is described by jewelers as "easy" or "hard." Solder with a lower melting point will be considered easy, while solders with a relatively high melting point will be considered hard. Silver solder is generally used to join precious metals in the process of jewelry repair or jewelry making.
