Correct Answer:
Option D —
Copper, zinc and nickel
Key Facts About German SilverDespite its name, German silver contains no actual silver. It is named "silver" only because of its bright, silvery-white appearance.
Composition: It typically consists of about 60% copper, 20% nickel, and 20% zinc.
Properties: It is highly valued for its hardness, toughness, and excellent resistance to corrosion.
Common Uses: Because it looks like silver but is much cheaper, it is frequently used for:
Tableware and cutlery (often as a base for silver plating).
Musical instruments (like flutes and saxophones).
Jewelry and decorative items.
Zippers and keys.
Why the other options are incorrect:
A) Copper and tin: This is the composition of Bronze.
B) Zinc, silver, and copper: While these metals are used in various alloys, they do not define German silver (which specifically lacks silver).
C) Copper and nickel: This is known as Cupronickel, often used in silver-colored circulation coins. While German silver contains these, it must also include zinc to be classified as such.
