Sn70Pb30 solder bar
Sn70Pb30 Lead Solder Bar
Sn70Pb30 is a higher-tin tin-lead solder bar designed for controlled soldering, tinning and industrial electronics processes where a 70/30 Sn-Pb composition is specified.

Higher-tin Sn-Pb solder bar for controlled production
With a higher tin content than many conventional leaded bar alloys, Sn70Pb30 provides a comparatively lower liquidus temperature and practical wetting performance for compatible materials and processes.
70% Tin Composition
Higher tin content supports suitable solderability and flow characteristics.
Controlled Melting Behavior
Approximate 183–195°C phase-change range for defined Sn-Pb process design.
Wave & Dip Compatibility
Suitable for solder pots, wave soldering and dip soldering after process validation.
Consistent Alloy Control
Composition inspection supports stable production and bath replenishment.
Standard Bar Dimensions
Supplied in practical bar form for handling and melting.
Export Supply Support
Carton packing, batch documents and OEM requirements can be discussed.
Recommended Use
Recommended for wave soldering, dip soldering, tinning, alloy replenishment and industrial electronics assembly where Sn70Pb30 is required.
Product Specifications
Core data for initial product selection. Final values must be confirmed against the approved specification, batch document or purchase order.
Typical Applications
Application suitability depends on substrate finish, flux selection, solder bath condition, temperature profile, joint design and regulatory requirements.
