Purpose: construction, electronics, electrical engineering.
Composition (up to several% of alloying elements):
– Sn-Ag-Cu,
– Sn-Ag,
– Sn-Cu.

The challenge with lead-free alloys is that they have a slightly higher melting point, higher surface tension, and poorer wetting compared to Sn-Pb . Therefore, we select the appropriate type of flux and adjust its amount to the process temperature.

Dimensions, packaging, marking:
– Dimension range: from 0.3 mm to 4 mm
– Wire type: solid wires; flux coated wires
– Spool dimensions: 100g; 250g; 1kg; 10kg
– Marking: labels with manufacturer's print, dimensions, net weight, type of flux
– Packaging: cartons
