Sn97Cu3 Lead-Free Solder Wire
Sn97Cu3
Lead-Free Solder Wire
Sn97Cu3 lead-free solder wire is a tin-copper alloy designed for applications requiring higher process temperature and stronger solder joint performance. With a melting point of approximately 300°C and available diameter from 0.3mm, it is suitable for industrial electronics, electrical components, and applications where higher thermal resistance is needed.
A higher-temperature SnCu solder wire for industrial use.
Sn97Cu3 solder wire has a higher copper content than common Sn99.3Cu0.7 solder wire, giving it a higher melting point and stronger suitability for applications where elevated soldering temperatures are acceptable. It is often selected for durable solder connections, industrial electronics, and heat-resistant soldering requirements.
Higher Melting Point
Designed for applications requiring higher thermal resistance than standard SnCu solder wire.
Stronger SnCu Alloy
Higher copper content supports durable solder joint performance.
Industrial Suitability
Applicable to electronic assemblies exposed to more demanding conditions.
Custom Supply Options
Available in different wire diameters, flux types, and packaging formats.
