Product Introduction
The company manufactures lead solder wire items by utilizing pure tin metal sourced from Yunnan, China. The production process involves stringent quality control measures, vacuum deoxygenation treatment, and the use of advanced automated equipment for extrusion production. These methods effectively manage the level of oxidation and the presence of impurities in both metallic and non-metallic forms.
Singway produces lead solder wire, the surface is smooth, bright, solder joint no bubbles, no cracks, can be customized according to customer requirements of various tin lead content, various wire diameter size solder wire.

The surface of the solder wire is even and sleek, with a shiny appearance. It has excellent ability to form strong connections quickly and consistently. When used for brazing, it does not create any splashes and leaves behind very little residue. Additionally, it has a transparent and colorless appearance.
