Question

uses of copper, iron, aluminum​

Answer 1

Answer:

Uses of Copper ,Iron, and Aluminium

Explanation:

Aluminium

Aluminium foils are used as wrappers for chocolates.

The fine dust of the metal is used in paints and lacquers.

Aluminium, being highly reactive, is also used in the extraction of chromium and manganese from their oxides. Wires of aluminium are used as electricity conductors.

Alloys containing aluminium, being light, are very useful.

Copper

Copper is used for making wires used in electrical industry and for water and steam pipes.

It is also used in several alloys that are rather tougher than the metal itself, e.g., brass (with zinc), bronze (with tin) and coinage alloy (with nickel).

Iron

Cast iron, which is the most important form of iron, is used for casting stoves, railway sleepers, gutter pipes, toys, etc. It is used in the manufacture of wrought iron and steel.

Wrought iron is used in making anchors, wires, bolts, chains and agricultural implements.

Steel finds a number of uses. Alloy steel is obtained when other metals are added to it.

Nickel steel is used for making cables, automobiles and aeroplane parts, pendulum, measuring tapes, chrome steel for cutting tools and crushing machines, and stainless steel for cycles, automobiles, utensils, pens, etc.

Answer 2

Uses of Copper:-

• It is used for making cables, electrical wires for various appliances because its a good conductor of heat.
• It is also used in making utensils, car radiators because it is a good conductor of heat.
• It is also used in alloys that are then used for making coins, pipes etc.

________________________________

Uses of Iron:-

• Alloy of iron is used in making utensils and knives.
• Iron is tough, malleable also with some content of iron, so it is used in making bolts, chains, wire nets etc.
• Pig iron is brittle with a high amount of carbon, so it is used in making cylinders, railings, sinks etc.

Uses of Aluminium:-

• It is used in manufacturing of utensils and electrical cables due to high conductivity of heat and electricity also.
• It is used for making paints to prevent iron rusting.
• It is used used in aircraft to make its body parts.
