Product composition: Sn99.93-Cu0.7 Product diameter: 315*15*11mm Product weight: 500g/piece Working temperature: 265-275 Flux method: manual dip tin, wave solder Product packaging: 20KG/carton Product use: suitable for welding of transformer products The characteristics of the tin bar: it has bright and full solder joints, and it will not be soldered and other undesirable phenomena. Add enough antioxidant elements, strong antioxidant ability. Made of pure tin, less tin dross, reducing unnecessary waste. After melting, the amount of slag is less than that of ordinary solder, and it has excellent oxidation resistance. After melting, the viscosity is low, the fluidity is good, and the weldability is high. Due to very few oxidation inclusions, the phenomenon of sharpening and bridging can be minimized, the welding quality is reliable, and the solder joints are bright and full.
