First of all let us discuss what are alloys :-

An alloy is a solid solution of metals with other metals or non-metals. An example of an alloy is Brass (Cu3Zn2). It is an alloy of copper (Cu) and Zinc (Zn).

Now, let's talk about German Silver.

A German Silver is an alloy of Zinc (Zn), Copper (Cu), and Nickel (Ni). (Option (c))

This alloy is a mixture of more than one metals.

The composition of these metals in German Silver are as under :-

Zinc (Zn) - 17.2 % to 19 %

Copper (Cu) - 50% to 61.6 %

Nickel (Ni) - 21.1 % to 30 %

German Silver is :-

• Hard
• Tough
• Ductile
• Malleable
• Doesn't lose its lustre that means it cannot tarnish
• Resistance to corrosion

Due to all these properties German silver is used in tableware, zippers, musical instruments, jewellery etc.
