Give the names and composition of alloys that are used for the following.
(a) making statues
(b) joining wires in electronic equipments
(c) making surgical instruments
(d) making bodies of aircrafts
(e) making accurate laboratory balances
(f) making bodies of ships

(a) Making statues: Statues are normally made of Bronze, whose constituents are copper and tin. Because bronze is very hard and resists corrosion, it is suitable for making statues.

(b) Joining wires in electronic equipments: Solder is widely used for joining wires in electronic equipments. Solder is an alloy of tin and lead. It has low melting point which makes it suitable for fusing copper wires in an electrical circuit.

(c) Making surgical instruments: Stainless steel is widely used for making surgical instruments. Its constituents are iron, chromium and nickel. Stainless steel is very strong and resists corrosion.

(d) Making bodies of aircrafts: Duralumin and magnalium are used for making bodies of aircraft. The constituents of duralumin are aluminium, copper, magnesium and manganese. The constituents of magnalium are aluminium and magnesium. Both duralumin and magnalium are strong as well as light. So, they are used in making bodies of aircrafts.

(e) Making accurate laboratory balances: Magnalium, an alloy of aluminium and magnesium, is widely used for making accurate laboratory balances. As it is light in weight, it is ​suitable for preparing balances.

(f) Making bodies of ships: Steel is used for making bodies of ships. The constituents of steel are iron and carbon. As steel is very strong, it is ideal for making bodies of ships.
