Alloy SAC0307

Alloy S‑Sn99 Ag0,3 Cu0,7

GENERAL CHARACTERISTICS

Alloy used in the electronics industry: wave soldering applications.

This ternary alloy, exclusively made from primary metals of very high purity, has an excellent performance / price ratio.

The silver content guarantees better reliability of the solder joints. When faced with other SnCu-type compositions (with or without adding a minor element), it secures your applications.

As with any new installation of a lead-free alloy for wave soldering, we recommend that you ensure regular monitoring of the contents of each metal (Sn / Ag / Cu and Pb for RoHS compliance: its rate must be less than 0.1%).

The addition of antioxidant tablets in the alloy bath slows down oxidation phenomena, while giving a better fluidity to the alloy.

Very good mechanical resistance.
Good ductility
Economic alloy
Bright alloy, not tarnishing.
Very good electrical conductivity.
