Solder-It SP-7 Silver Solder Paste 7.1 Grams | Soldering Flux Paste for Electronic Components, Home Improvement, and Wiring | Silver Solder for Jewelry Making and Repair | Lead-Free Solder Flux

Description

h2>Product Overview

Our Solder-It SP-7 Silver Solder Paste is a high-performance, lead-free flux designed for precision soldering in electronics, jewelry, and home improvement projects. Made with pure silver, it delivers superior electrical conductivity and corrosion resistance, making it ideal for brass, bronze, nickel, stainless steel, copper, and steel joints. The paste comes in a convenient syringe for precise, mess-free application, and its low melting point (430°F) ensures smooth flow during soldering. With a tensile strength of 10,000–25,000 PSI, it’s 5x stronger than conventional solder wire and re-melts at 650°F for easy repairs. The product is non-toxic and safe for both hobbyists and professionals.h2>Usage
