Solder-It SP-7 Silver Solder Paste 7.1 Grams | Soldering Flux for...

Product Details EASY TO USE: Our silver solder paste syringe offers a no-mess, no-waste way to disperse the soldering paste. It’s designed for easy application with little to no skill required for DIY projects and tasks. HIGH CONDUCTIVITY: It’s excellent for electrical work and instrument assembly where high electrical conductivity is required. You can use it on jewelry, electronic components, wiring, and circuit board work. CORROSION-RESISTANT: Our solder flux paste stays bright and doesn't turn black. This makes it ideal for brass, bronze, nickel, stainless steel joints, copper-based metals, and steel. EXTREMELY TOUGH: It has 10,000-25,000 PSI tensile strength, making it 5x stronger than conventional solder wire. It also has a low melting point that allows it to flow smoothly at 430 F and re-melt at 650 F. SETS INSTANTLY: It helps prevent soldering failure due to moving parts while soldering because of the instant setting. It’s also non-toxic and contains no lead, cadmium, antimony, or zinc.
