Anti iron tip erosion super low Ag flux cored wire solder

S03X7Ca-72M
Sn 0.3Ag 0.7Cu 0.03Co

0.3 Ag for longer-lasting iron tips

Inhibits erosion of Fe plating

Co added to S03X7Ca-72M forms a barrier layer at the iron tip surface, which inhibits erosion of the tip. S03X7Ca-72M significantly reduces wear of iron tips compared to regular lead-free solder.

Prevents bridging in slide soldering

72M series contain new activators for improved wettability and new resin composition for better flux coverage.
They can prevent bridging even at defect prone conditions such as low iron tip temperature or fast sliding speed.

Ultimate cost reduction by flux-cored solder

The low Ag composition of 0.3% reduces product prices, while prevention of iron tip erosion reduces running costs. S03X7Ca-72M offers dual cost reduction effects.
