$\bold{ \pink{i).}{ \underline{ \underline \pink{\: brass}}}→}$

➜ Brass is an alloy of Copper and Zinc ( Cu and Zn ), It contains 80% copper and 28% zinc. Brass is more malleable and more strong that pure copper..Its colour is also more golden..Brass is used for making cooking utensils, screws, nuts, bolts, wires, tubes, scientific instruments like microscopes and ornaments..Brass is also used for making vessels like flower vases and flitting like that of fancy lamps.

$\bold{ \pink{ii).}{ \underline{ \underline \pink{\: bronze}}}→}$

➜ Bronze is an alloy of Copper and Tin ( Cu and Sn ). It contains 90% copper and 10% tin. Bronze is very tough and highly resistant to corrosion. It is used for making statues, coins, medals, cooking utensils and ship's propellers.

$\bold{ \pink{iii).}{ \underline{ \underline \pink{\: solder}}}→}$

➜ Solder is an alloy of lead and tin ( Pb and Sn ). It contains 50% lead and 50% tin. The Melting point of an alloy is less than that of pure metals. Solder is an alloy which has a low melting point. so, it is used for soldering or welding electrical wires together.

$\bold{ \pink{iv).}{ \underline{ \underline \pink{\: amalgam}}}→}$

➜ an alloy of Mercury metal with one or more other metal is known as an amalgam. A solution of sodium metal in liquid Mercury metal is called sodium amalgam. An amalgam consisting of Mercury, silver, tin and zinc is used by dentists for fillings in teeth.

for more information :-

The electrical conductivity of an alloy is less than that of pure metals. For example, brass (an alloy of Copper and zinc) and bronze(an alloy of Copper and tin) are not good conductors of electricity but pure copper is an excellent conductor of electricity and used for making electrical circuits.
