MGC-4900 MG Chemicals Lead Free Solder Sn96 is a lead free solder made of tin, copper and silver which conform to impurity requirements making it a high quality grade perfect for any solder jobs. Leaves behind a hard non-conductive solder that requires no cleaning.
- Various size spools for the avid electronics enthusiast or electronics professional
- Thickness of wire: 21 gauge, 0.032” diameter for joining small to large components
- Has superior “solder-ability” to make it easy to use
- One pound of this lead free solder yields 27% more solder in length than a lead solder
- Easily de-solders and leaves no residue when removed using a de-soldering agent
- This is a lead free solder made of 96.3% tin, 0.7% copper and 3% silver as a replacement to the standard lead and tin solder
- One year manufacturer warranty
