Question 1 of 27070

Q

Solder is an alloy of __________.

🔍 Key Concepts

• Common soft solder composition used in electrical and plumbing work • Difference between soft solder and hard/silver brazing alloys • Typical metals that melt at relatively low temperatures for joining copper wires or pipes

💭 Think About

• Think about what metal you usually see on the outside of old electrical solder wire and what low‑melting metal is mixed with it to improve flow. • Which pair of metals in the choices is known for having a relatively low melting point and being used to join copper pipes or electrical components? • Eliminate metal pairs that are rare, toxic in specialized ways, or typically used for high‑temperature or structural alloys rather than low‑temperature joining.

✅ Before You Answer

• Recall which metals are commonly associated with electrical solder on circuit boards and wiring. • Check which answer choice contains a metal famous for low melting point and good wetting properties on copper and brass. • Eliminate combinations involving uncommon alloying elements for basic joining work on board a vessel.
