What Type of Solder Do You Use for Silver Soldering?
The type of solder you use for silver soldering depends on the type of metal you solder and the requirements of the soldered joint. Considerations include appearance, strength, corrosion and temperature at which the joint will operate.

Silver Solder
-
Not all applications use the same silver solder. All silver solders have at least some silver. A wide variety of silver solder alloys contain as little as 2 percent or as high as 56 percent silver.
Alloys
-
The alloys that make up silver solder include copper, cadmium, tin, zinc and nickel. The exact combination of these metals determine a wide variety of characteristics for many different applications.
-
Melting Point
-
The melting point means the temperature at which a solder will flow onto a joint. Harder solders require higher temperatures than softer solders.
Types of Metals Soldered
-
The metals that silver solder fuses include copper, silver, steel, stainless steel, nickel, tungsten carbine and others. Fusing together two different metals requires a careful selection of a silver solder type.
Applications
-
Jewelry, electrical connections, plumbing, cooking utensils or boilers all have different solder requirements. You would not use the same silver solder for the same metals in each application.
