Lead Sheet Metal
• One of the oldest sheet metals

Soldering
• The joining of two or more pieces of metal by using an alloy with a lower melting point than the pieces being joined
The Make-Up of Solder cont’d.
• As you increase the Tin %, the melting point of the solder is lowered
Flux• Removes/Cleans the oxide
film from the surface of metal• Solder would not “stick”
without the use of flux• May come in many different
forms
