Terne sheet metal is brass alloyed with steel and is coated on both sides with a lead-tin alloy.

• A. True
• B. False
• C. Terne is coated on both sides with a zinc alloy
• D. Terne uses a brass core only

Answer: (B)

Terne sheet metal uses a steel base, not brass. The defining feature is a lead-tin alloy coating applied to the steel surface, often on both sides for corrosion protection. Brass is a copper-zinc alloy, so a brass core would be incorrect, and terne does not use a zinc coating.
