Tin alloy weldments are structural components manufactured using high-purity tin-based alloy materials through precision welding processes. Our products primarily employ eco-friendly alloy formulations such as Sn99.3/Cu0.7, exhibiting excellent welding performance and mechanical strength. During welding, tin alloys demonstrate superior fluidity and wettability, forming bright and饱满 solder joints. The outstanding oxidation resistance significantly reduces dross formation. These weldments are suitable for various processes including wave soldering and manual dip soldering, with operating temperatures typically controlled within 265±5℃ range to ensure consistent welding quality.
