KappZapp7R™ – 1mm (.039”) diameter wire on 1/2 lb spool

KappZapp7R™ Rosin-cored Solder has rapidly become the audio industry standard for electrical / electronic Copper applications. The 7% Silver solder creates extremely clean conductive joints with high strength, ductility and corrosion resistance. The center of the solder contains a mildly-acidic natural rosin flux. When the solder is heated, the flux is released and removes the oxide coating to allow a strong bond to form. No additional flux is required when using KappZapp7R cored solder. The flux residue can be is removed with warm water or alcohol and a clean rag.

Ideal for small wires and small electronic parts.

The ½ lb spool contains about 120 feet of solder.
