This rosin-core lead-free silver solder is perfect for many different kinds of hobby or electronics projects and electrical work. It is made of a combination of tin, silver, and copper with flux in the core for a strong, long lasting bond. Silver solder is preferred over lead solder for its higher-conductivity, lower-resistance, and stronger solder joints.
