Answer 2

Answer:

OBJECTIVES OF MAKING ALLOY

1. To increase chemical reactivity
2. to modify chemical reactivity
3. to increase the hardness
4. to increase tensile strength
5. to produce good casting
6. to lower the melting point

TYPES OF ALLOYS & THIER USES

Brass :-

In making utensils.

Bronze :-

In making coins, bell and utensils.

German Silver :-

In making utensils.

Solder :-

For soldering.

Stainless steel :-

For making utensils and surgical cutlery.

Nickel steel :-

For making electrical wire, automobile parts.

PREPARATION OF ALLOY

The majority of alloys are prepared by mixing metals in the molten state; then the mixture is poured into metal or sand moulds and allowed to solidify. Generally the major ingredient is melted first; then the others are added to it and should completely dissolve.
