The Perfect 50gm High Quality 6040 Soldering Wire (0.8mm Diameter) is a commonly used consumable in electronics soldering. The “6040” composition means it contains 60% tin (Sn) and 40% lead (Pb), which is the standard eutectic ratio offering excellent soldering performance. Key Features: Composition: 60% Tin, 40% Lead (Sn60/Pb40) Diameter: 0.8 mm – suitable for both small and medium-sized joints. Weight: 50 grams spool. Flux Core: Contains rosin flux for smooth flow and good wetting on copper and other metals. Melting Point: ~183–190 °C (low melting range ensures quick soldering). Shiny Finish: Provides strong, reliable, and shiny joints. Applications: General electronics soldering of wires, components, and PCBs. Ideal for Arduino projects, sensors, and DIY electronics. Used in repair work (mobile phones, circuit boards, appliances). Advantages: Smooth flow with minimal spattering. Low melting point reduces risk of damaging sensitive components. Produces durable and conductive joints. ⚠️ Note: Since this solder contains lead, care should be taken while handling:
