Answer 1

$\mathfrak{\huge{\underline{Answer:}}}$

${\huge{ \underline{ \underline{ \sf \: Alloys:}}}}$

$\star$ An Alloy is a homogeneous mixture of two or more metals,or a metal and a non-metal. The properties of given metal can be modified significantly by adding appropriate amount of other metals,or non-metals,to form alloys.

$\textbf{ \underline{ \underline{ \sf \:Few\:Alloys\:and\:their\:uses :}}}$

1) Name = Steel

Made From = Iron + Carbon

Uses : Construction Material,Machine Parts

____________________

2) Name = Brass

Made From = Copper + Zinc

Uses : Cooking utensils,nuts and bolts

____________________

3) Name = Alnico

Made From = Aluminium + Nickel + Cobalt

Uses : Magnets

____________________

4) Name = German Silver

Made From = Copper + Zinc + Nickel

Uses : Tableware

____________________

5) Name = Gun Metal

Made From = Copper + Tin + Zinc

Uses : Gun-barrels

Properties which make them useful over Pure Metals :

$\star$ They are more resistant to corrosion than the pure metal.

$\star$ Impart shine and lustre.

$\star$ They are generally stronger and harder than metals.

Answer 2

Answer:

alloy is a homogeneous mixture contained of two or more metals or non metals.

properties

=it is resistance to prevent corrosion.

it is mixed with substance to make harder.

gold is mixed with copper and bronze.
