Product Introduction
This 3% silver lead-free wire has better electrical conductivity and ductility than traditional tin-copper alloys, and is a high-end product in the lead-free wire series.
1. Improve electrical conductivity: Adding 3% silver can significantly improve the electrical conductivity of the solder wire, making it ideal for applications requiring high electrical conductivity. In areas such as electronic component manufacturing, highly conductive welding materials can ensure the stability and efficiency of current transmission.
2. Improve ductility: The addition of 3% silver can improve the ductility of the solder wire, making it easier to form a uniform and reliable welded joint. This is very important for welding complex shaped components and connectors to improve welding quality and reliability.
