Question
Write the composition of solder.
✓
Answer
A higher tin composition gives the solder higher corrosion resistances, but raises the melting point. Another common composition is 11% tin, 37% lead, 42% bismuth, and 10% cadmium. This combination has a low melting point and is useful forsoldering components that are sensitive to heat.
