Sn99Ag0.3Cu0.7 solder bar
Sn99Ag0.3Cu0.7 Solder Bar
Sn99Ag0.3Cu0.7 solder bar is a low-silver tin-silver-copper alloy for lead-free wave soldering and industrial assembly where silver cost and stable process performance must be balanced.
Low-silver SAC solder bar for cost-conscious production
Compared with higher-silver SAC alloys, SAC0307 uses less silver while retaining a Sn-Ag-Cu alloy system. Final performance depends on bath control, copper dissolution, flux and process conditions.
Low-Silver SAC Alloy
Reduced silver content helps manage material cost.
217°C Melting Point
Suitable for standard lead-free process planning.
Tin-Silver-Copper System
Maintains a SAC alloy structure for compatible production requirements.
Wave Soldering Use
Bar form supports solder-pot filling and replenishment.
Bath Control Support
Composition monitoring helps manage copper and impurity levels.
Production Supply
Packaging, batch documentation and custom requirements can be reviewed.
Recommended Use
Recommended for wave soldering, dip soldering, terminal tinning and electronics production where Sn99Ag0.3Cu0.7 is specified.
Product Specifications
Core data for initial product selection. Final alloy tolerance, bar size and packaging should be confirmed against the approved specification or purchase order.
Typical Applications
Application suitability depends on the substrate finish, flux, solder-bath condition, temperature profile, joint design and reliability requirements.
